## Introduction
The **Eclipse Deeplearning4J** (DL4J) ecosystem is a set of projects intended to support all the needs of a JVM based deep learning application. This means starting with the raw data, loading and preprocessing it from wherever and whatever format it is in to building and tuning a wide variety of simple and complex deep learning networks.
The DL4J stack comprises of:
- **DL4J**: High level API to build MultiLayerNetworks and ComputationGraphs with a variety of layers, including custom ones. Supports importing Keras models from h5, including tf.keras models (as of 1.0.0-M2) and also supports distributed training on Apache Spark
- **ND4J**: General purpose linear algebra library with over 500 mathematical, linear algebra and deep learning operations. ND4J is based on the highly-optimized C++ codebase LibND4J that provides CPU (AVX2/512) and GPU (CUDA) support and acceleration by libraries such as OpenBLAS, OneDNN (MKL-DNN), cuDNN, cuBLAS, etc
- **SameDiff** : Part of the ND4J library, SameDiff is our automatic differentiation / deep learning framework. SameDiff uses a graph-based (define then run) approach, similar to TensorFlow graph mode. Eager graph (TensorFlow 2.x eager/PyTorch) graph execution is planned. SameDiff supports importing TensorFlow frozen model format .pb (protobuf) models. Import for ONNX, TensorFlow SavedModel and Keras models are planned. Deeplearning4j also has full SameDiff support for easily writing custom layers and loss functions.
- **DataVec**: ETL for machine learning data in a wide variety of formats and files (HDFS, Spark, Images, Video, Audio, CSV, Excel etc)
- **LibND4J** : C++ library that underpins everything. For more information on how the JVM accesses native arrays and operations refer to [JavaCPP](https://github.com/bytedeco/javacpp)
All projects in the DL4J ecosystem support Windows, Linux and macOS. Hardware support includes CUDA GPUs (10.0, 10.1, 10.2 except OSX), x86 CPU (x86_64, avx2, avx512), ARM CPU (arm, arm64, armhf) and PowerPC (ppc64le).
## Prerequisites
This example repo consists of several separate Maven Java projects, each with their own pom files. Maven is a popular build automation tool for Java Projects. The contents of a "pom.xml" file dictate the configurations. Read more about how to configure Maven [here](https://deeplearning4j.konduit.ai/config/maven).
Users can also refer to the [simple sample project provided](./mvn-project-template/pom.xml) to get started with a clean project from scratch.
Build tools are considered standard software engineering best practice. Besides this the complexities posed by the projects in the DL4J ecosystem make dependencies too difficult to manage manually. All the projects in the DL4J ecosystem can be used with other build tools like Gradle, SBT etc. More information on that can be found [here](https://deeplearning4j.konduit.ai/config/buildtools).
## Support
For help with the examples, please go to our [support forum](https://community.konduit.ai/)
Note for users of 1.0.0-beta7 and prior, some examples and modules have been removed to reflect
changes in the framework's direction. Please see and comment on our post [here](https://community.konduit.ai/t/upcoming-removal-of-modules-and-roadmap-changes/1240)
If you would like a workaround for something you may be missing,
please feel free to post on the forums, and we will do what we can to help you.
## Example Content
Projects are based on what functionality the included examples demonstrate to the user and not necessarily which library in the DL4J stack the functionality lives in.
Examples in a project are in general separated into "quickstart" and "advanced".
Each project README also lists all the examples it contains, with a recommended order to explore them in.
- [dl4j-examples](dl4j-examples/README.md)
This project contains a set of examples that demonstrate use of the high level DL4J API to build a variety of neural networks.
Some of these examples are end to end, in the sense they start with raw data, process it and then build and train neural networks on it.
- [tensorflow-keras-import-examples](tensorflow-keras-import-examples/README.md)
This project contains a set of examples that demonstrate how to import Keras h5 models and TensorFlow frozen pb models into the DL4J ecosystem. Once imported into DL4J these models can be treated like any other DL4J model - meaning you can continue to run training on them or modify them with the transfer learning API or simply run inference on them.
- [dl4j-distributed-training-examples](dl4j-distributed-training-examples/README.md)
This project contains a set of examples that demonstrate how to do distributed training, inference and evaluation in DL4J on Apache Spark. DL4J distributed training employs a "hybrid" asynchronous SGD approach - further details can be found in the distributed deep learning documentation [here](https://deeplearning4j.konduit.ai/distributed-deep-learning/intro)
- [cuda-specific-examples](cuda-specific-examples/README.md)
This project contains a set of examples that demonstrate how to leverage multiple GPUs for data-parallel training of neural networks for increased performance.
- [samediff-examples](samediff-examples/README.md)
This project contains a set of examples that demonstrate the SameDiff API. SameDiff (which is part of the ND4J library) can be used to build lower level auto-differentiating computation graphs. An analogue to the SameDiff API vs the DL4J API is the low level TensorFlow API vs the higher level of abstraction Keras API.
- [data-pipeline-examples](data-pipeline-examples/README.md)
This project contains a set of examples that demonstrate how raw data in various formats can be loaded, split and preprocessed to build serializable (and hence reproducible) ETL pipelines.
- [nd4j-ndarray-examples](nd4j-ndarray-examples/README.md)
This project contains a set of examples that demonstrate how to manipulate NDArrays. The functionality of ND4J demonstrated here can be likened to NumPy.
- [rl4j-examples](rl4j-examples/README.md)
This project contains examples of using RL4J, the reinforcement learning library in DL4J.
- [android-examples](android-examples/README.md)
This project contains an Android example project, that shows DL4J being used in an Android application.
## Feedback & Contributions
While these set of examples don't cover all the features available in DL4J the intent is to cover functionality required for most users - beginners and advanced. File an issue [here](https://github.com/eclipse/deeplearning4j-examples/issues) if you have feedback or feature requests that are not covered here. We are also available via our [community forum](https://community.konduit.ai/) for questions.
We welcome contributions from the community. More information can be found [here](CONTRIBUTORS.md)
We **love** hearing from you. Cheers!

confluentinc/kafka-streams-examples | Demo applications and code examples for Apache Kafka's Streams API. | null | # Kafka Streams Examples
This project contains code examples that demonstrate how to implement real-time applications and event-driven
microservices using the Streams API of [Apache Kafka](http://kafka.apache.org/) aka Kafka Streams.
For more information take a look at the
[**latest Confluent documentation on the Kafka Streams API**](http://docs.confluent.io/current/streams/), notably the
[**Developer Guide**](https://docs.confluent.io/platform/current/streams/developer-guide/index.html)

# Available examples
This repository has several branches to help you find the correct code examples for the version of Apache Kafka and/or
Confluent Platform that you are using. See [Version Compatibility Matrix](#version-compatibility) below for details.
There are three kinds of examples:
* **Examples under [src/main/](src/main/)**: These examples are short and concise. Also, you can interactively
test-drive these examples, e.g. against a local Kafka cluster. If you want to actually run these examples, then you
must first install and run Apache Kafka and friends, which we describe in section
[Packaging and running the examples](#packaging-and-running). Each example also states its exact requirements and
instructions at the very top.
* **Examples under [src/test/](src/test/)**: These examples should test applications under [src/main/](src/main/).
Unit Tests with TopologyTestDriver test the stream logic without external system dependencies.
The integration tests use an embedded Kafka
clusters, feed input data to them (using the standard Kafka producer client), process the data using Kafka Streams,
and finally read and verify the output results (using the standard Kafka consumer client).
These examples are also a good starting point to learn how to implement your own end-to-end integration tests.
* **Ready-to-run Docker Examples**: These examples are already built and containerized.

## Examples: Unit Tests
The stream processing of Kafka Streams can be **unit tested** with the `TopologyTestDriver` from the
`org.apache.kafka:kafka-streams-test-utils` artifact. The test driver allows you to write sample input into your
processing topology and validate its output.

## Examples: Integration Tests
We also provide several **integration tests**, which demonstrate end-to-end data pipelines. Here, we spawn embedded Kafka
clusters and the [Confluent Schema Registry](https://github.com/confluentinc/schema-registry), feed input data to them
(using the standard Kafka producer client), process the data using Kafka Streams, and finally read and verify the output
results (using the standard Kafka consumer client).
Additional examples may be found under [src/test/](src/test/java/io/confluent/examples/streams/).
> Tip: Run `mvn test` to launch the tests.

# Docker Example: Kafka Music demo application
This containerized example launches:
* Confluent's Kafka Music demo application for the Kafka Streams API, which makes use of
[Interactive Queries](http://docs.confluent.io/current/streams/developer-guide.html)
* a single-node Apache Kafka cluster with a single-node ZooKeeper ensemble
* a [Confluent Schema Registry](https://github.com/confluentinc/schema-registry) instance
The Kafka Music application demonstrates how to build of a simple music charts application that continuously computes,
in real-time, the latest charts such as latest Top 5 songs per music genre. It exposes its latest processing results
-- the latest charts -- via Kafka’s [Interactive Queries](http://docs.confluent.io/current/streams/developer-guide.html#interactive-queries)
feature via a REST API. The application's input data is in Avro format, hence the use of Confluent Schema Registry,
and comes from two sources: a stream of play events (think: "song X was played") and a stream of song metadata ("song X
was written by artist Y").
You can find detailed documentation at
https://docs.confluent.io/current/streams/kafka-streams-examples/docs/index.html.

## Confluent Platform
The code in this repository requires [Confluent Schema Registry](https://github.com/confluentinc/schema-registry).
See [Version Compatibility Matrix](#version-compatibility) for further details, as different branches of this
repository have different Confluent Platform requirements.
* [Confluent Platform Quickstart](http://docs.confluent.io/current/quickstart.html) (how to download and install)
* [Confluent Platform documentation](http://docs.confluent.io/current/)

Also, each example states its exact requirements at the very top.
<a name="requirements-ide"/>
## Using IntelliJ or Eclipse
If you are using an IDE and import the project you might end up with a "missing import / class not found" error.
Some Avro classes are generated from schema files and IDEs sometimes do not generate these classes automatically.
To resolve this error, manually run:
```shell
$ mvn -Dskip.tests=true compile
```
If you are using Eclipse, you can also right-click on `pom.xml` file and choose _Run As > Maven generate-sources_.
<a name="requirements-java"/>
## Java 8+
Some code examples require Java 8+, primarily because of the usage of
[lambda expressions](https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html).
IntelliJ IDEA users:
* Open _File > Project structure_
* Select "Project" on the left.
* Set "Project SDK" to Java 1.8.
* Set "Project language level" to "8 - Lambdas, type annotations, etc."
<a name="requirements-scala"/>
## Scala
> Scala is required only for the Scala examples in this repository. If you are a Java developer you can safely ignore
> this section.
If you want to experiment with the Scala examples in this repository, you need a version of Scala that supports Java 8
and SAM / Java lambda (e.g. Scala 2.11 with `-Xexperimental` compiler flag, or 2.12).
If you are compiling with Java 9+, you'll need to have Scala version 2.12+ to be compatible with the Java version.
<a name="packaging-and-running"/>
# Packaging and running the Application Examples
The instructions in this section are only needed if you want to interactively test-drive the
[application examples](#examples-apps) under [src/main/](src/main/).
> **Tip:** If you only want to run the integration tests (`mvn test`), then you do not need to package or install
> anything -- just run `mvn test`. These tests launch embedded Kafka clusters.
The first step is to install and run a Kafka cluster, which must consist of at least one Kafka broker as well as
at least one ZooKeeper instance. Some examples may also require a running instance of Confluent schema registry.
The [Confluent Platform Quickstart](http://docs.confluent.io/current/quickstart.html) guide provides the full
details.
In a nutshell:
```shell
# Ensure you have downloaded and installed Confluent Platform as per the Quickstart instructions above.
# Start ZooKeeper
$ ./bin/zookeeper-server-start ./etc/kafka/zookeeper.properties
# In a separate terminal, start Kafka broker
$ ./bin/kafka-server-start ./etc/kafka/server.properties
# In a separate terminal, start Confluent Schema Registry
$ ./bin/schema-registry-start ./etc/schema-registry/schema-registry.properties
# Again, please refer to the Confluent Platform Quickstart for details such as
# how to download Confluent Platform, how to stop the above three services, etc.
```
The next step is to create a standalone jar ("fat jar") of the [application examples](#examples-apps):
```shell
# Create a standalone jar ("fat jar")
$ mvn clean package
# >>> Creates target/kafka-streams-examples-7.8.0-0-standalone.jar
```
> Tip: If needed, you can disable the test suite during packaging, for example to speed up the packaging or to lower
> JVM memory usage:
>
> ```shell
> $ mvn -DskipTests=true clean package
> ```
You can now run the application examples as follows:
```shell
# Run an example application from the standalone jar. Here: `WordCountLambdaExample`
$ java -cp target/kafka-streams-examples-7.8.0-0-standalone.jar \
io.confluent.examples.streams.WordCountLambdaExample
```
The application will try to read from the specified input topic (in the above example it is ``streams-plaintext-input``),
execute the processing logic, and then try to write back to the specified output topic (in the above example it is ``streams-wordcount-output``).
In order to observe the expected output stream, you will need to start a console producer to send messages into the input topic
and start a console consumer to continuously read from the output topic. More details in how to run the examples can be found
in the [java docs](src/main/java/io/confluent/examples/streams/WordCountLambdaExample.java#L31) of each example code.
If you want to turn on log4j while running your example application, you can edit the
[log4j.properties](src/main/resources/log4j.properties) file and then execute as follows:
```shell
# Run an example application from the standalone jar. Here: `WordCountLambdaExample`
$ java -cp target/kafka-streams-examples-7.8.0-0-standalone.jar \
-Dlog4j.configuration=file:src/main/resources/log4j.properties \
io.confluent.examples.streams.WordCountLambdaExample
```
Keep in mind that the machine on which you run the command above must have access to the Kafka/ZooKeeper clusters you
configured in the code examples. By default, the code examples assume the Kafka cluster is accessible via
`localhost:9092` (aka Kafka's ``bootstrap.servers`` parameter) and the ZooKeeper ensemble via `localhost:2181`.
You can override the default ``bootstrap.servers`` parameter through a command line argument.

# Development
This project uses the standard maven lifecycle and commands such as:
```shell
$ mvn compile # This also generates Java classes from the Avro schemas
$ mvn test # Runs unit and integration tests
$ mvn package # Packages the application examples into a standalone jar
```

# Building From the Command Line: Quick Version
Before you can run the examples from this repository, you must install
[JDK8](http://www.oracle.com/technetwork/java/javase/downloads/index.html), the
*Java Development Kit* for version 8 of the language.
If you just want to download and check the code, [Download
Here](https://github.com/BruceEckel/OnJava8-Examples/archive/refs/heads/master.zip)
and [unzip it](#unpacking-a-zip-archive) into your destination directory. Open
a [shell/command window](#appendix-a-command-line-basics) and move into the
root of that directory. You'll know you are in the right directory if you see
the files `gradlew` and `gradlew.bat`.
You'll need an Internet connection the first time you compile the code,
because Gradle needs to first install itself, then all the support libraries.
Once these are installed you can perform additional compiling and running
offline.
On Mac/Linux, enter:
```
./gradlew test
```
(If you get a *Permission denied* error, run `chmod +x ./gradlew`)
On Windows, enter
```
gradlew test
```
If all goes well, the tests will run. Everything should complete without errors.
All the book examples are in the subdirectory `Examples` in subdirectories
corresponding to the atom names.
# Building From the Command Line: Detailed Instructions
If you are not familiar with the command line, first read [Command-Line
Basics](#appendix-a-command-line-basics).
## Install Java
You must first install the *Java Development Kit* (JDK).
### Windows
1. Follow the instructions to [install Chocolatey](https://chocolatey.org/).
2. At a [shell prompt](#appendix-a-command-line-basics), type: `choco install
jdk8` (you may also select a more recent version, like `jdk11`). The
installation process takes some time, but when it's finished Java is installed
and the necessary environment variables are set.
### Macintosh
The Mac comes with a much older version of Java that won't work for the
examples in this book, so you'll need to update it to (at least) Java 8.
1. Follow the instructions at this link to [Install HomeBrew](http://brew.sh/)
2. At a [shell prompt](#appendix-a-command-line-basics), first type
`brew update`. When that completes, enter `brew cask install java`.
**NOTE:** Sometimes the default version of Java that you get with the above
installation will be too recent and not validated by the Mac's security
system. If this happens you'll either need to turn off the security by hand
or install an earlier version of Java. For either choice, you'll need to Google
for answers on how to solve the problem (often the easiest approach is to just
search for the error message produced by the Mac).
### Linux
Use the standard package installer with the following [shell commands](#appendix-a-command-line-basics):
*Ubuntu/Debian*:
1. `sudo apt-get update`
2. `sudo apt-get install default-jdk`
*Fedora/Redhat*:
```
su -c "yum install java-1.8.0-openjdk"
```
## Verify Your Installation
[Open a new shell](#appendix-a-command-line-basics) and type:
```
java -version
```
You should see something like the following (Version numbers and actual text
will vary):
```
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)
OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)
```
If you see a message that the command is not found or not recognized, review
the installation instructions. If you still can't get it to work, check
[StackOverflow](http://stackoverflow.com/search?q=installing+java).
## Installing and Running the Book Examples
Once you have Java installed, the process to install and run the book examples
is the same for all platforms:
1. Download the book examples from the
[GitHub Repository](https://github.com/BruceEckel/OnJava8-Examples/archive/refs/heads/master.zip).
2. [Unzip](#unpacking-a-zip-archive) the downloaded file into the directory of your choice.
3. Use the Windows Explorer, the Mac Finder, or Nautilus or equivalent on Linux
to browse to the directory where you uzipped `OnJava8-Examples`, and
[open a shell](#appendix-a-command-line-basics) there.
4. If you're in the right directory, you should see files named `gradlew` and
`gradlew.bat` in that directory, along with numerous other files and
directories. The directories correspond to the chapters in the book.
5. At the shell prompt, type `gradlew test` (Windows) or `./gradlew test`
(Mac/Linux).
The first time you do this, Gradle will install itself and numerous other
packages, so it will take some time. After everything is installed, subsequent
builds and runs will be much faster.
Note that you must be connected to the Internet the first time you run `gradlew`
so that Gradle can download the necessary packages.
# Appendix A: Command-Line Basics
Because it is possible for a "dedicated beginner" to learn programming from
this book, you may not have previously used your computer's command-line shell.
If you have, you can go directly to the
[installation instructions](#building-from-the-command-line-detailed-instructions).
## Editors
To create and modify Java program files—the code listings shown in this
book—you need a program called an *editor*. You'll also need the editor to
make changes to your system configuration files, which is sometimes required
during installation.
Programming editors vary from heavyweight *Integrated Development Environments*
(IDEs, like Eclipse, NetBeans and IntelliJ IDEA) to more basic text
manipulation applications. If you already have an IDE and are comfortable with
it, feel free to use that for this book.
Numerous explanations in this book are specific to IntelliJ IDEA so if you
don't already have an IDE you might as well start with IDEA. There are many
other editors; these are a subculture unto themselves and people sometimes get
into heated arguments about their merits. If you find one you like better, it's
not too hard to change. The important thing is to choose one and get
comfortable with it.
## The Shell
If you haven't programmed before, you might be unfamiliar with your operating
system *shell* (also called the *command prompt* in Windows). The shell harkens
back to the early days of computing when everything happened by typing commands
and the computer responded by displaying responses—everything was text-based.
Although it can seem primitive in the age of graphical user interfaces, a shell
provides a surprising number of valuable features.
To learn more about your shell than we cover here, see
[Bash Shell](https://en.wikipedia.org/wiki/Bash_(Unix_shell)) for Mac/Linux
or [Windows Shell](https://en.wikipedia.org/wiki/Windows_shell).
### Starting a Shell
**Mac**: Click on the *Spotlight* (the magnifying-glass icon in the upper-right
corner of the screen) and type "terminal." Click on the application that looks
like a little TV screen (you might also be able to hit "Return"). This starts a
shell in your home directory.
**Windows**: First, start the Windows Explorer to navigate through your
directories:
- *Windows 7*: click the "Start" button in the lower left corner of the screen.
In the Start Menu search box area type "explorer" and then press the "Enter"
key.
- *Windows 8*: click Windows+Q, type "explorer" and then press the "Enter" key.
- *Windows 10*: click Windows+E.
Once the Windows Explorer is running, move through the folders on your computer
by double-clicking on them with the mouse. Navigate to the desired folder. Now
click the file tab at the top left of the Explorer window and select "Open
Windows Powershell." This opens a shell in the destination directory.
**Linux**: To open a shell in your home directory:
- *Debian*: Press Alt+F2. In the dialog that pops up, type 'gnome-terminal'
- *Ubuntu*: Either right-click on the desktop and select 'Open Terminal', or
press Ctrl+Alt+T
- *Redhat*: Right-click on the desktop and select 'Open Terminal'
- *Fedora*: Press Alt+F2. In the dialog that pops up, type 'gnome-terminal'
### Directories
*Directories* are one of the fundamental elements of a shell. Directories hold
files, as well as other directories. Think of a directory as a tree with
branches. If `books` is a directory on your system and it has two other
directories as branches, for example `math` and `art`, we say that you have a
directory `books` with two *subdirectories* `math` and `art`. We refer to them
as `books/math` and `books/art` since `books` is their *parent* directory.
Note that Windows uses backslashes rather than forward slashes to separate the
parts of a directory.
### Basic Shell Operations
The shell operations shown here are approximately identical across operating
systems. For the purposes of this book, here are the essential operations in a
shell:
- **Change directory**: Use `cd` followed by the name of the
directory where you want to move, or `cd ..` if you want to move
up a directory. If you want to move to a different directory while
remembering where you came from, use `pushd` followed by the different
directory name. Then, to return to the previous directory, just say
`popd`.
- **Directory listing**: `ls` (`dir` in Windows) displays all the files and
subdirectory names in the current directory. Use the wildcard `*` (asterisk) to
narrow your search. For example, if you want to list all the files ending in
".kt," you say `ls *.kt` (Windows: `dir *.kt`). If you want to list the
files starting with "F" and ending in ".kt," you say `ls F*.kt` (Windows:
`dir F*.kt`).
- **Create a directory**: use the `mkdir` ("make directory") command
(Windows: `md`), followed by the name of the directory you want to create.
For example, `mkdir books` (Windows: `md books`).
- **Remove a file**: Use `rm` ("remove") followed by the name of the file
you wish to remove (Windows: `del`). For example, `rm somefile.kt` (Windows:
`del somefile.kt`).
- **Remove a directory**: use the `rm -r` command to remove the files in
the directory and the directory itself (Windows: `deltree`). For example,
`rm -r books` (Windows: `deltree books`).
- **Repeat a command**: The "up arrow" on all three operating
systems moves through previous commands so you can edit and
repeat them. On Mac/Linux, `!!` repeats the last command and
`!n` repeats the nth command.
- **Command history**: Use `history` in Mac/Linux or press the F7 key in Windows.
This gives you a list of all the commands you've entered. Mac/Linux provides
numbers to refer to when you want to repeat a command.
### Unpacking a Zip Archive
A file name ending with `.zip` is an archive containing other files in a
compressed format. Both Linux and Mac have command-line `unzip` utilities, and
it's possible to install a command-line `unzip` for Windows via the Internet.
However, in all three systems the graphical file browser (Windows Explorer, the
Mac Finder, or Nautilus or equivalent on Linux) will browse to the directory
containing your zip file. Then right-mouse-click on the file and select "Open"
on the Mac, "Extract Here" on Linux, or "Extract all ..." on Windows.
# Appendix B: Testing
The test system is built in so that we (the authors) can verify the correctness
of what goes into the book.
You don't need to run the tests, but if you want to, you can just run `gradlew
test` (on Windows) or `./gradlew test` (Mac/Linux).
To compile and run everything, the command is:
`gradlew run`
If you are on a Unix/Linux based system, you must select the local directory for all commands, for example:
`./gradlew run`
To only compile everything, the command is:
`gradlew compileJava`
To compile only a single chapter (including dependencies), use for example:
`gradlew :strings:compileJava`
To run only a single chapter, say:
`gradlew :strings:run`
Gradle can also be used to run a single program. Here, we run the **ReplacingStringTokenizer.java**
program in the **strings** chapter subdirectory:
`gradlew :strings:ReplacingStringTokenizer`
However, if the file name is unique throughout the book (the majority are), you
can just give the program name, like this:
`gradlew ReplacingStringTokenizer`
Note that all commands are run from the base directory where the example code is
installed, and where you find the `gradlew` script.
You can learn about other options by just typing `gradlew` with no arguments.
# Appendix C: Troubleshooting
If any terminology or processes described here remain unclear to you, you can
usually find explanations or answers through [Google](https://www.google.com/).
For more specific issues or problems, try
[StackOverflow](http://stackoverflow.com/). Sometimes you can find installation
instructions on [YouTube](https://www.youtube.com/).
Sometimes a Gradle build will be unable to connect to the internet and download
the necessary components, producing an error message containing:
```
javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
```
Normally this means you have multiple Java installations on your machine
(applications built with Java ordinarily install their own version of Java), and
somehow the `cacerts` security file is interfering with the `cacerts` file for
the Java you have installed. It can be difficult to know which `cacerts` file is
interfering with yours. The brute-force approach is to search for all the
`cacerts` files on your machine and begin uninstalling the associated
applications---or in some cases, simply removing the directory containing the
`cacerts` file---until the Gradle build begins to work. You might also need to
adjust some environment variables and/or your path. Once you get the Gradle
build working successfully, you should be able to reinstall any applications you
removed in the process.

mapstruct/mapstruct-examples | Examples for using MapStruct | null | # MapStruct Examples
This repository contains examples showing how to use [MapStruct](http://mapstruct.org/), a Java annotation processor for the generation of type-safe bean mapping classes.
Currently, the following examples exist:
* [_mapstruct-on-ant_](mapstruct-on-ant): Shows how to use MapStruct in Ant-based projects; to build this example, run `ant build` on the command line
* [_mapstruct-on-gradle_](mapstruct-on-gradle): Shows how to use MapStruct in Gradle-based projects; to build the example project, run `./gradlew clean build` on the command line
* [_mapstruct-on-bazel_](mapstruct-on-bazel): Shows how to use MapStruct in Bazel-based projects; to build the example project, run `bazel build //...` on the command line, to test the project, run `bazel test //...`.
* [_mapstruct-lombok_](mapstruct-lombok): Shows how to use MapStruct together with Lombok (with both a Maven `pom.xml` and a Gradle `build.gradle`); to build the example project, run either `mvn clean install` or `./gradlew clean build` on the command line
* [_mapstruct-iterable-non-iterable_](mapstruct-iterable-to-non-iterable): Shows how by means of a mapper util class conversions can be made from an iterable- to its non-iterable element

### Just a gif
### RxJava 1.x 到 RxJava 2.x 变化一览
RxJava 1.x -> RxJava 2.x
* `onCompleted` -> `onComplete` - without the trailing d
* `Func1` -> `Function`
* `Func2` -> `BiFunction`
* `CompositeSubscription` -> `CompositeDisposable`
* `limit` operator has been removed - Use `take` in RxJava2
* and much more.
### 一些操作符的解释
* `Map` -> transform the items emitted by an Observable by applying a function to each item
* `Zip` -> combine the emissions of multiple Observables together via a specified function and emit single items for each combination based on the results of this function
* `Filter` -> emit only those items from an Observable that pass a predicate test
* `FlatMap` -> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable
* `Take` -> emit only the first n items emitted by an Observable
* `Reduce` -> apply a function to each item emitted by an Observable, sequentially, and emit the final value
* `Skip` -> suppress the first n items emitted by an Observable
* `Buffer` -> periodically gather items emitted by an Observable into bundles and emit these bundles rather than emitting the items one at a time
* `Concat` -> emit the emissions from two or more Observables without interleaving them
* `Replay` -> ensure that all observers see the same sequence of emitted items, even if they subscribe after the Observable has begun emitting items
* `Merge` -> combine multiple Observables into one by merging their emissions
### 尽情地下载运行，开始感受RxJava 2.x 的强大魅力吧~

This Maven multi-module project contains all the Struts 2 example applications that are part of the Getting Started Struts 2 tutorials at http://struts.apache.org.
To build all the example applications run the Maven command:
```
mvn -e clean package
```
In the project's root folder, Maven will build each module and create a `.war` file in the target sub-folder of each module.
You can then copy the `.war` files to your Servlet container (e.g. Tomcat, Jetty, GlassFish, etc).
There is a README file in each module with instructions and the URL to view that application.

oktadev/java-microservices-examples | Java Microservices: Spring Boot, Spring Cloud, JHipster, Spring Cloud Config, and Spring Cloud Gateway | java jhipster jhipster-microservices kubernetes microservices microservices-architecture netflix-zuul oauth2 reactive-microservices spring-boot spring-cloud spring-cloud-config spring-cloud-gateway | # Java Microservices with Spring Boot & Spring Cloud 🍃☁️
This repository contains examples of how to build a Java microservices architecture with Spring Boot, Spring Cloud, and Netflix Eureka.
This repository has five examples in it:
1. A bare-bones microservices architecture with Spring Boot, Spring Cloud, Eureka Server, and Zuul.
2. A microservices architecture that's generated with JHipster and configured centrally with Spring Cloud Config.
3. A microservices architecture that uses Spring Cloud Gateway and Spring WebFlux to show reactive microservices.
4. A JHipster-generated reactive microservices architecture with Spring Cloud Gateway and Spring WebFlux.
5. A JHipster 7 + Kubernetes example that deploys to Google Cloud with sealed secrets.
We think you'll enjoy them all!
1. See [Java Microservices with Spring Boot and Spring Cloud][blog-spring-boot-spring-cloud] for an overview of the first example.
2. Read [Java Microservices with Spring Cloud Config and JHipster][blog-spring-cloud-config] to learn about microservices with JHipster.
3. Refer to [Secure Reactive Microservices with Spring Cloud Gateway][blog-spring-cloud-gateway] to learn about Spring Cloud Gateway and reactive microservices.
4. Refer to [Reactive Java Microservices with Spring Boot and JHipster][blog-reactive-jhipster] to see how JHipster makes reactive microservices a breeze.
5. Peruse [Kubernetes to the Cloud with Spring Boot and JHipster][blog-k8s] to see how JHipster simplifies Kubernetes deployments.
**Prerequisites:** [Java 11](https://sdkman.io/sdks#java) and an internet connection.

## Spring Boot + Spring Cloud Example
To install this example, run the following commands:
```bash
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/spring-boot+cloud
```
The `api-gateway` and `car-service` projects are already pre-configured to be locked down with OAuth 2.0 and Okta. That means if you try to run them, you won't be able to login until you create an account, and an application in it.
### Create a Web Application in Okta
Log in to your Okta Developer account (or [sign up](https://developer.okta.com/signup/) if you don't have an account).
1. From the **Applications** page, choose **Add Application**.
2. On the Create New Application page, select **Web**.
3. Give your app a memorable name, add `http://localhost:8080/login/oauth2/code/okta` as a Login redirect URI, select **Refresh Token** (in addition to **Authorization Code**), and click **Done**.
Copy the issuer (found under **API** > **Authorization Servers**), client ID, and client secret into the `application.properties` of the `api-gateway` and `car-service` projects.
```properties
okta.oauth2.issuer=https://{yourOktaDomain}/oauth2/default
okta.oauth2.client-id=$clientId
okta.oauth2.client-secret=$clientSecret
```
Then, run all the projects with `./mvnw` in separate terminal windows. You should be able to navigate to `http://localhost:8761` and see the apps have been registered with Eureka.
Then, navigate to `http://localhost:8080/cool-cars` in your browser, log in with Okta, and see the resulting JSON.
## JHipster + Spring Cloud Config Example
To install this example, run the following commands:
```bash
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/jhipster
```
Create Docker containers for all gateway and microservice applications:
```bash
mvn -Pprod verify com.google.cloud.tools:jib-maven-plugin:dockerBuild
```
### Create a Web Application in Okta
Log in to your Okta Developer account (or [sign up](https://developer.okta.com/signup/) if you don't have an account).
1. From the **Applications** page, choose **Add Application**.
2. On the Create New Application page, select **Web**.
3. Give your app a memorable name, add `http://localhost:8080/login/oauth2/code/okta` as a Login redirect URI, select **Refresh Token** (in addition to **Authorization Code**), and click **Done**.
4. To configure Logout to work in JHipster, **Edit** your app, add `http://localhost:8080` as a Logout redirect URI, then click **Save**.
Rather than modifying each of your apps for Okta, you can use Spring Cloud Config in JHipster Registry to do it. Open `docker-compose/central-server-config/application.yml` and add your Okta settings.
The client ID and secret are available on your app settings page. You can find the issuer under **API** > **Authorization Servers**.
```yaml
spring:
security:
oauth2:
client:
provider:
oidc:
issuer-uri: https://{yourOktaDomain}/oauth2/default
registration:
oidc:
client-id: {yourClientId}
client-secret: {yourClientSecret}
```
The registry, gateway, blog, and store applications are all configured to read this configuration on startup.
Start all your containers from the `docker-compose` directory:
```bash
docker-compose up -d
```
Before you can log in to the registry, you'll need to add redirect URIs for JHipster Registry, ensure your user is in a `ROLE_ADMIN` group and that groups are included in the ID token.
Log in to your Okta dashboard, edit your OIDC app, and add the following Login redirect URI:
* `http://localhost:8761/login/oauth2/code/oidc`
You'll also need to add a Logout redirect URI:
* `http://localhost:8761`
Then, click **Save**.
### Create Groups and Add Them as Claims to the ID Token
JHipster is configured by default to work with two types of users: administrators and users. Keycloak is configured with users and groups automatically, but you need to do some one-time configuration for your Okta organization.
Create a `ROLE_ADMIN` group (**Users** > **Groups** > **Add Group**) and add your user to it. Navigate to **API** > **Authorization Servers**, and click on the the `default` server. Click the **Claims** tab and **Add Claim**. Name it `groups`, and include it in the ID Token. Set the value type to `Groups` and set the filter to be a Regex of `.*`. Click **Create**.
Now when you hit `http://localhost:8761` or `http://localhost:8080`, you should be able to log in with Okta!
## Spring Cloud Gateway Example
To install this example, run the following commands:
```bash
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/spring-cloud-gateway
```
The `api-gateway` and `car-service` projects are already pre-configured to be locked down with OAuth 2.0 and Okta. That means if you try to run them, you won't be able to login until you create an account, and an application in it.
If you already have an Okta account, see the **Create a Web Application in Okta** section below. Otherwise, we created a Maven plugin that configures a free Okta developer account + an OIDC app (in under a minute!).
To use it, run `./mvnw com.okta:okta-maven-plugin:setup` to create an account and configure the gateway to work with Okta.
Copy the `okta.*` properties from the gateway's `src/main/resources/application.properties` to the same file in the `car-service` project.
Then, run all the projects with `./mvnw` in separate terminal windows. You should be able to navigate to `http://localhost:8761` and see the apps have been registered with Eureka.
Then, navigate to `http://localhost:8080/cars` in your browser, log in with Okta, and see the resulting JSON.
### Create a Web Application in Okta
Log in to your Okta Developer account (or [sign up](https://developer.okta.com/signup/) if you don't have an account).
1. From the **Applications** page, choose **Add Application**.
2. On the Create New Application page, select **Web**.
3. Give your app a memorable name, add `http://localhost:8080/login/oauth2/code/okta` as a Login redirect URI and click **Done**.
Copy the issuer (found under **API** > **Authorization Servers**), client ID, and client secret into the `application.properties` of the `api-gateway` and `car-service` projects.
```properties
okta.oauth2.issuer=https://{yourOktaDomain}/oauth2/default
okta.oauth2.client-id=$clientId
okta.oauth2.client-secret=$clientSecret
```
## Reactive Microservices with JHipster Example
To install this example, run the following commands:
```bash
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/reactive-jhipster
```
The JHipster Registry and Spring Cloud Config are pre-configured to use Okta. That means if you try to run them, you won't be able to login until you create an account, and an application in it.
Install the Okta CLI using the instructions on [cli.okta.com](https://cli.okta.com) and come back here when you're done. If you don't have an Okta developer account, run `okta register`.
**NOTE**: You can also use your browser and Okta's developer console to register an app. See [JHipster's security documentation](https://www.jhipster.tech/security/#okta) for those instructions.
From the gateway project's directory, run `okta apps create jhipster`. Accept the default redirect URIs.
This process does several things:
1. Registers an OIDC app in Okta with JHipster's configured redirect URIs.
2. Creates `ROLE_ADMIN` and `ROLE_USER` groups and adds your user to both.
3. Creates a `groups` claim and adds it to ID tokens.
4. Creates a `.okta.env` file with the values you'll need to talk to Okta.
Spring Cloud Config allows you to distribute Spring's configuration between apps. Update `gateway/src/main/docker/central-server-config/localhost-config/application.yml` to use your Okta app settings. You can find the values for each property in the `.okta.env` file.
```yaml
spring:
security:
oauth2:
client:
provider:
oidc:
issuer-uri: https://<your-okta-domain>/oauth2/default
registration:
oidc:
client-id: <client-id>
client-secret: <client-secret>
```
Save your changes. These values will be distributed to the JHipster Registry, gateway, blog, and store apps. Start all the services and apps using the following commands:
```shell
cd gateway
docker-compose -f src/main/docker/keycloak.yml up -d #jhkeycloakup
docker-compose -f src/main/docker/postgresql.yml up -d #jhpostgresqlup
docker-compose -f src/main/docker/jhipster-registery up -d #jhregistryup
./gradlew
```
Open a new terminal window, start the blog app's Neo4j database, and then the app itself.
```shell
cd ../blog
docker-compose -f src/main/docker/neo4j.yml up -d #jhneo4jup
./gradlew
```
Then, open another terminal window, start the store app's MongoDB database, and the microservice.
```shell
cd ../store
docker-compose -f src/main/docker/mongodb.yml up -d #jhmongoup
./gradlew
```
Now, open a new incognito browser window, go to `http://localhost:8080`, and sign in. Rejoice that using Okta for authentication works!
**TIP**: You can also run everything using Docker Compose. See the [blog post](https://developer.okta.com/blog/2021/01/20/reactive-java-microservices#run-your-microservices-stack-with-docker-compose) for how to do that.
## Kubernetes + Reactive Java with JHipster Example
To install this example, run the following commands:
```bash
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/jhipster-k8s/k8s
```
If you don't have JHipster installed, install it.
```shell
npm i -g generator-jhipster@7
```
Run JHipster's [Kubernetes sub-generator](https://www.jhipster.tech/kubernetes/).
```shell
jhipster k8s
```
You will be prompted with several questions. The answers will be pre-populated from choices I made when creating this app. Answer as follows, changing the Docker repository name to yours, or leaving it blank if you don't have one.
- Type of application: **Microservice application**
- Root directory: **../**
- Which applications? `<select all>`
- Set up monitoring? **No**
- Which applications with clustered databases? select **store**
- Admin password for JHipster Registry: `<generate one>`
- Kubernetes namespace: **demo**
- Docker repository name: `<your docker hub username>`
- Command to push Docker image: `docker push`
- Enable Istio? **No**
- Kubernetes service type? **LoadBalancer**
- Use dynamic storage provisioning? **Yes**
- Use a specific storage class? `<leave empty>`
### Install Minikube to Run Kubernetes Locally
If you have Docker installed, you can run Kubernetes locally with Minikube. Run `minikube start` to begin.
```shell
minikube --memory 8g --cpus 8 start
```
Build Docker images for each app. In the {`gateway`, `blog`, `store` } directories, run the following Gradle command (where `<image-name>` is `gateway`, `store`, or `blog`).
```shell
./gradlew bootJar -Pprod jib -Djib.to.image=<docker-repo-name>/<image-name>
```
> You can also build your images locally and publish them to your Docker daemon. This is the default if you didn't specify a base Docker repository name.
>
> ```shell
> # this command exposes Docker images to minikube
> eval $(minikube docker-env)
> ./gradlew -Pprod bootJar jibDockerBuild
> ```
>
> Because this publishes your images locally to Docker, you'll need to make modifications to your Kubernetes deployment files to use `imagePullPolicy: IfNotPresent`.
>
> ```yaml
> - name: gateway-app
> image: gateway
> imagePullPolicy: IfNotPresent
> ```
>
> Make sure to add this `imagePullPolicy` to the following files:
>
> - `k8s/gateway-k8s/gateway-deployment.yml`
> - `k8s/blog-k8s/blog-deployment.yml`
> - `k8s/store-k8s/store-deployment.yml`
### Register an OIDC App for Auth
Install the Okta CLI using the instructions on [cli.okta.com](https://cli.okta.com) and come back here when you're done. If you don't have an Okta developer account, run `okta register`.
**NOTE**: You can also use your browser and Okta's developer console to register an app. See [JHipster's security documentation](https://www.jhipster.tech/security/#okta) for those instructions.
From the gateway project's directory, run `okta apps create jhipster`. Accept the default redirect URIs.
This process does several things:
1. Registers an OIDC app in Okta with JHipster's configured redirect URIs.
2. Creates `ROLE_ADMIN` and `ROLE_USER` groups and adds your user to both.
3. Creates a `groups` claim and adds it to ID tokens.
4. Creates a `.okta.env` file with the values you'll need to talk to Okta.
Update `k8s/registry-k8s/application-configmap.yml` to contain your OIDC settings from the `.okta.env` file the Okta CLI just created. The Spring Cloud Config server reads from this file and shares the values with the gateway and microservices.
```yaml
data:
application.yml: |-
...
spring:
security:
oauth2:
client:
provider:
oidc:
issuer-uri: https://<your-okta-domain>/oauth2/default
registration:
oidc:
client-id: <client-id>
client-secret: <client-secret>
```
To configure the JHipster Registry to use OIDC for authentication, modify `k8s/registry-k8s/jhipster-registry.yml` to enable the `oauth2` profile.
```yaml
- name: SPRING_PROFILES_ACTIVE
value: prod,k8s,oauth2
```
Then, in the `k8s` directory, start your engines!
```shell
./kubectl-apply.sh -f
```
You can see if everything starts up using the following command.
```shell
kubectl get pods -n default
```
You can use the name of a pod with `kubectl logs` to tail its logs.
```shell
kubectl logs <pod-name> --tail=-1 -n default
```
You can use port-forwarding to see the JHipster Registry.
```shell
kubectl port-forward svc/jhipster-registry -n default 8761
```
Open a browser and navigate to `http://localhost:8761`. You'll need to sign in with your Okta credentials.
Once all is green, use port-forwarding to see the gateway app.
```shell
kubectl port-forward svc/gateway -n default 8080
```
Then, go to `http://localhost:8080`, and you should be able to add blogs, posts, tags, and products.

assertj/assertj-examples | Examples illustrating AssertJ assertions | assertj assertj-assertions java | ## AssertJ examples
AssertJ examples is divided in two : assertions-examples (core, guava and joda assertions) and AssertJ swing modules.
The **main** branch contains examples with the latest released version of AssertJ modules (for Java 8).
There are several branches that contain examples for the ongoing development versions of AssertJ modules. That means you have to build the according AssertJ modules by your own before new features compile. The following table contains these special branches that are merged into the main each time the module is released.
| Branch | Modules |
| ----------------------------- | ------------------------------------------ |
| with-latest-snapshot-versions | Core 3.x for Java 8 |
| with-latest-swing-snapshot | Swing |
### AssertJ assertions examples
**assertj-examples/assertions-examples** contains executable AssertJ assertions examples that you can run as JUnit tests.
Please have a look at **[assertions examples sources](assertions-examples/src/test/java/org/assertj/examples)**.
The **main** branch contains examples with the latest released version of AssertJ modules for Java 8, similarly the **java-7** branch contains examples of AssertJ modules for Java 7.
You should be able to build those two branches with `mvn clean install` command.
In your IDE, add `src/test/generated-assertions` to the project java test sources otherwise you will have errors/missing classes.
This is the folder where custom assertions classes are generated by default by the maven assertions generator plugin.
Note that Intellij Idea wrongly adds `src/test/generated-assertions` to the production sources when it should be added the **test sources**, you will have to fix that in your module/project settings.
Building **with-latest-snapshot-versions** is a little more complicated :
- you need to build the needed SNAPSHOT dependencies before - most probably assertj-core and maybe other modules.
- run `mvn clean install` in `assertj-examples/assertions-examples`.
- In your IDE, add `src/test/generated-assertions` to the project java sources if you IDE shows errors/missing classes.
### AssertJ-Swing examples
The **main** branch contains examples with the latest released version of AssertJ modules => you should be able to build it with mvn clean install command.
**assertj-swing-aut** contains the AUT (application under test) that is tested by the examples.
**assertj-swing-junit-examples** contains executable AssertJ-Swing examples that you can inspect and run as JUnit tests.
Please have a look at **[swing-junit-examples sources](assertj-swing-junit-examples/src/test/java/org/assertj/swing/junit/examples)**.
**assertj-swing-testng-examples** contains executable AssertJ-Swing examples that you can inspect and run as TestNG tests.
Please have a look at **[swing-testng-examples sources](assertj-swing-testng-examples/src/test/java/org/assertj/swing/testng/examples)**.
## Contributing
Contributing is easy, only two rules to follow :
* Checkout the snapshot branch corresponding to your examples, it should be `with-latest-snapshot-versions` most of the time (not main!)
* Use **[AssertJ code Eclipse formatting preferences](https://github.com/joel-costigliola/assertj-core/blob/main/src/ide-support/assertj-eclipse-formatter.xml)** (for Idea users, it is possible to import it)
* Add FUN examples ! ;-)
Thanks !

Examples for Learning Spark
===============
Examples for the Learning Spark book. These examples require a number of libraries and as such have long build files. We have also added a stand alone example with minimal dependencies and a small build file
in the mini-complete-example directory.
These examples have been updated to run against Spark 1.3 so they may
be slightly different than the versions in your copy of "Learning Spark".
Requirements
==
* JDK 1.7 or higher
* Scala 2.10.3
- scala-lang.org
* Spark 1.3
* Protobuf compiler
- On debian you can install with sudo apt-get install protobuf-compiler
* R & the CRAN package Imap are required for the ChapterSixExample
* The Python examples require urllib3
Python examples
===
From spark just run ./bin/pyspark ./src/python/[example]
Spark Submit
===
You can also create an assembly jar with all of the dependencies for running either the java or scala
versions of the code and run the job with the spark-submit script
`./sbt/sbt assembly` OR `mvn package`
`cd $SPARK_HOME; ./bin/spark-submit --class com.oreilly.learningsparkexamples.[lang].[example] ../learning-spark-examples/target/scala-2.10/learning-spark-examples-assembly-0.0.1.jar`

amehlhase316/ser321examples | null | null | # ser321examples
All examples in this repository are for you to play with and to learn about the different concepts in this class. This repo is still a "living" thing. As we progress we might add more examples or make changes.
You can use these samples to develop your solutions but you need to reference things if you copy parts of the repo into your solution and it is NOT ok to use any of the examples here and submit them as your own. Each assignment that you submit has to have a significant own contribution to show you understand the concepts and can develop a solution on your own.
## Advise
It is advised that you fork this repository so that you have your own version and can also make changes to your own repo to test different scenarios. Then clone that repo to your main machine and your second machine.
If we make changes to the repository we will notify you in the Slack #example_repo channel. See here about forking and keeping your version up to date <https://docs.github.com/en/free-pro-team@latest/github/getting-started-with-github/fork-a-repo?>
## Development
All examples are developed by the teaching team:
Many examples are used and adapted from Dr. Lindquist and Dr. Gary.
Others were developed by Dr. Mehlhase, David Clements and Aman Kaushik.
## Running the examples
The examples should all have Gradle files. The separate folders have a Gradle project but the "inner" folders also have separate Gradle files. Please check the comments and files so you know how to run the examples.
## Suggestions
If you find any issues or have suggestions on how to improve the repo, the Gradle files etc. feel free to let us know. We are happy to accept Pull Requests if you think you come up with something good.
## Have fun
Feel free to play with these examples, the better you understand these small examples the easier your coding assignments will be.
Best

This module contains a number of examples that you can take a look at and try out yourself. Please take a look at the readme of each individual example for more details on how the example works and how to run it yourself (either locally or on Kubernetes).
Since Kogito aims at supporting both Quarkus and Spring Boot each example usually provides both type of projects.
- Default branch is `stable`, pointing to the latest released version.
- **[You can also check all versions by looking at releases.](https://github.com/kiegroup/kogito-examples/releases/latest)**
## Use alternative Quarkus platforms
The Quarkus quickstarts by default currently use the Quarkus core BOM.
If you want to use an alternative BOM when building the Quarkus quickstarts you can override the `quarkus.platform.*` properties. The following example shows how to set `quarkus.platform.artifact-id` to use the quarkus-universe-bom.
```
mvn -Dquarkus.platform.artifact-id=quarkus-universe-bom clean install
```
Because the Kogito project is part of the Quarkus Platform, the same applies also to Kogito BOM being used.
By default `org.kie.kogito:kogito-bom` is used, but, when needed, this can be overridden using Maven properties:
* `kogito.bom.*` for Kogito BOM overrides
The properties defined in each of the modules and can be overridden as follows:
* Kogito BOM
```
mvn -Dkogito.bom.group-id=io.quarkus.platform -Dkogito.bom.artifact-id=quarkus-kogito-bom -Dkogito.bom.version=2.2.3.Final
```
> Note: It's important to keep BOM versions aligned when overriding. In case of Quarkus Platform this means using a single
> version value for all two (`quarkus.platform.version`, `kogito.bom.version`) properties.

## 说明
目前该项目实现了 zuul(路由模块), config-server(配置管理), eureka server（服务注册和发现）, zipkin（服务调用追踪）,hystrix, turbine stream (熔断分析)
simple-service,simple-serviceB两个待发现的服务
simple-ui (一个用angular写的前端页面)
路由功能实现在 cloud-api-gateway 模块，注册到eureka server上面，所有的请求访问 http://localhost:5555, 然后根据路由规则
```
zuul.routes.api-a.path: /cloud-simple-service/**
zuul.routes.api-a.serviceId: cloud-simple-service
zuul.routes.api-b.path: /cloud-simple-serviceB/**
zuul.routes.api-b.serviceId: cloud-simple-serviceB
zuul.routes.api-ui.path: /cloud-simple-ui/**
zuul.routes.api-ui.serviceId: cloud-simple-ui
```
分别请求到 注册到eureka server的cloud-simple-service 和 cloud-simple-serviceB服务。
服务的架构图:

## 使用指南
* 先决条件
本机安装rabbitmq,并启动
```
rabbitmq-server
```
本机安装mysql,并启动且创建dev和test数据库,并分别创建表
```
mysql.server start
mysql -uroot
CREATE TABLE `user` (
`id` int(11) NOT NULL,
`username` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8
dev数据库的user表中插入数据
INSERT INTO `user` VALUES (1,'dev1'),(2,'dev2'),(3,'dev3');
test数据库的user表中插入数据
INSERT INTO `user` VALUES (1,'test1'),(2,'test2'),(3,'test3');
```
* 运行各模块
```
cd cloud-api-gateway
mvn spring-boot:run #端口5555
cd cloud-config-server
mvn spring-boot:run #端口8888
cd cloud-eureka-server
mvn spring-boot:run #端口8761
cd cloud-simple-service
mvn spring-boot:run #端口8081
cd cloud-simple-service
mvn spring-boot:run --server.port=8082 # cloud-simple-service 以8082端口再次启动服务
cd cloud-simple-ui
mvn spring-boot:run #端口8090
cd cloud-zipkin
mvn spring-boot:run #端口9966
```
* 打开浏览器输入网址并浏览效果
```
查看Eureka Server
http://localhost:8761 #查看eureka
```

```
请求simple service, simple service2, simple serviceB
http://localhost:8081/user #simple service
结果:
[
{
id: 1,
username: "dev1"
},
{
id: 2,
username: "dev2"
},
{
id: 3,
username: "dev3"
}
]
http://localhost:8082/user #simple service2
结果:
[
{
id: 1,
username: "dev1"
},
{
id: 2,
username: "dev1"
},
{
id: 3,
username: "dev1"
}
]
http://localhost:8091/user #simple serviceB
结果:
Result from simpleserviceB
```
本项目实现了通过spring-cloud-bus, 传播config-server中config的变化.下面动手验证之.
1. 下载配置git repository
```
git clone git@github.com:zpng/spring-cloud-config-demo.git
```
根目录下有个cloud-config-repo目录,该目录下有两个文件:
cloud-simple-service-dev.properties
cloud-simple-service-test.properties
分别是cloud-simple-service在 dev和test环境下的配置信息
cloud-simple-service-dev.properties内容:
```
mysqldb.datasource.url=jdbc\:mysql\://localhost\:3306/dev?useUnicode\=true&characterEncoding\=utf-8
mysqldb.datasource.username=root
mysqldb.datasource.password=
logging.level.org.springframework.web:DEBUG
```
cloud-simple-service-test.properties内容:
```
mysqldb.datasource.url=jdbc\:mysql\://localhost\:3306/test?useUnicode\=true&characterEncoding\=utf-8
mysqldb.datasource.username=root
mysqldb.datasource.password=
logging.level.org.springframework.web:DEBUG
```
1. 修改 cloud-simple-service-dev.properties 内容,
```
mysql url中使用的dev数据库变为test数据库
mysqldb.datasource.url=jdbc\:mysql\://localhost\:3306/dev?useUnicode\=true&characterEncoding\=utf-8
->
mysqldb.datasource.url=jdbc\:mysql\://localhost\:3306/test?useUnicode\=true&characterEncoding\=utf-8
git add -A
git commit -m "MOD: update config"
git push origin master #将修改push到git repositoy
```
1. 此时并需要重启config-server或者simple-service,只需要发送一个POST请求到config-server,并通过bus传播到使用该配置文件的服务中.
```
curl -X POST http://localhost:8888/bus/refresh #(config-server启动在8888端口)
```
此时刷新前端页面
```
http://localhost:8081/user #simple service
http://localhost:8082/user #simple service2
```
发现数据都已变成:
```
[
{
id: 1,
username: "test1"
},
{
id: 2,
username: "test2"
},
{
id: 3,
username: "test3"
}
]
```
---
1. 验证路由逻辑
cloud-api-gateway服务使用了zuul进行请求转发,转发规则如下:
```
# routes to serviceId
zuul.routes.api-a.path: /cloud-simple-service/**
zuul.routes.api-a.serviceId: cloud-simple-service
zuul.routes.api-b.path: /cloud-simple-serviceB/**
zuul.routes.api-b.serviceId: cloud-simple-serviceB
zuul.routes.api-ui.path: /cloud-simple-ui/**
zuul.routes.api-ui.serviceId: cloud-simple-ui
```
并且zuul服务中进行了token验证,需要请求参数中包含accessToken,accessToken可以为任意值,如果不包含该参数则请求不能
转发过去.
```
http://localhost:5555/cloud-simple-ui/users?accessToken=test
结果:
[
{
id: 1,
username: "test1"
},
{
id: 2,
username: "test2"
},
{
id: 3,
username: "test3"
}
]
http://localhost:5555/cloud-simple-serviceB/user?accessToken=tbbsxxxxd
结果: Result from simpleserviceB
http://localhost:5555/cloud-simple-service/user?accessToken=xxxdaew
结果:
[
{
id: 1,
username: "test1"
},
{
id: 2,
username: "test2"
},
{
id: 3,
username: "test3"
}
]
```
可见zuul已经完全发挥了它的路由作用.
1. Hystrix
Hystrix是熔断器, Hystrx Dashboard实现了监控单个Hystrix stream的功能.
```
http://localhost:8022/hystrix/
```
打开后页面如下:
在其中输入
```
http://localhost:8090/hystrix.stream
```
(cloud-simple-ui服务),即可监控该服务的stream,如下图
注意需要请求几次cloud-simple-ui服务,该图上才会有结果.
1. Turbine
本示例使用了turbine-amqp, 然后各个需要统计hystrix stream的微服务,包含依赖
```
<!--for turbine stream-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-hystrix-stream</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>
```
即可将stream 发送到rabbitmq队列,然后turbine stream项目获取这些stream, 然后显示在图示上,这样跟之前的区别是可以监控所有
的微服务,而不是单个主机的stream.
同样打开
```
http://localhost:8022/hystrix/
```
在其中输入
```
http://localhost:8989/turbine.stream
```
则可以看到如下图所示
如图所示可以看到 cloud-simple-service, cloud-simple-serviceB, cloud-simple-ui 共3个服务的Hystrix Stream.
1. Zipkin
zipkin可以跟踪微服务的调用以及,各个路径上面的时间,进而分析瓶颈.
打开
```
http://localhost:9966
```
trace如下图:
dependencies如下图:

RefactoringGuru/design-patterns-java | Design Pattern Examples in Java | design-patterns java | # Design Patterns in Java
This repository is part of the [Refactoring.Guru](https://refactoring.guru/design-patterns) project.
It contains Java examples for all classic GoF design patterns.
## Requirements
The examples were written in Java 8, but also tested in Java 9.
For the best experience, we recommend working with examples in IntelliJ IDEA. The Community Edition of IDE is available for free (https://www.jetbrains.com/idea/download/).
After downloading or cloning this repository to your computer, import its root directory into a New project:
- Either through start dialog: Select "Import Project" option and skip through the rest of the steps.
- Or via the main menu: File > New > Project from Existing Sources...
After importing the project, you will be able to run examples by right-clicking "Demo" files inside every example and selecting the "Run" command from the context menu.
## Roadmap
- [ ] Add detailed comments all classes.
- [ ] Add structure-only examples.
## Contributor's Guide
We appreciate any help, whether it's a simple fix of a typo or a whole new example. Just [make a fork](https://help.github.com/articles/fork-a-repo/), do your change and submit a [pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/).
Here's a style guide which might help you to keep your changes consistent with our code:
1. All code should meet the [Google Java Style Guide](https://google.github.io/styleguide/javaguide.html)
2. Try to hard wrap the code at 80th's character. It helps to list the code on the website without scrollbars.
3. Examples should match following package convention: refactoring_guru.{pattern}.{example_name}. Example:
```java
package refactoring_guru.factory_method.ui_example.buttons;
class Button {
...
```
4. Places classes into separate files.
5. Group classes into sub-packages. It helps people to understand dependencies of a class by glancing over its imports. Example:
```java
package refactoring_guru.factory_method.example.buttons;
class Button {
...
```
```java
package refactoring_guru.factory_method.example.factories;
import Button;
class Factory {
...
```
6. Comments may or may not have language tags in them, such as this:
```java
/**
* EN: All products families have the same varieties (MacOS/Windows).
*
* This is a MacOS variant of a button.
*
* RU: Все семейства продуктов имеют одни и те же вариации (MacOS/Windows).
*
* Это вариант кнопки под MacOS.
*/
```
Don't be scared and ignore the non-English part of such comments. If you want to change something in a comment like this, then do it. Even if you do it wrong, we'll tell you how to fix it during the Pull Request.

CamelCookbook/camel-cookbook-examples | Example source code for Apache Camel Developer's Cookbook | apache-camel examples integration packtpub | Apache Camel Developer's Cookbook, 2nd Edition Samples
======================================================
[](https://travis-ci.org/CamelCookbook/camel-cookbook-examples)
[](https://waffle.io/CamelCookbook/camel-cookbook-examples?utm_source=badge)
This project contains the sample code for the [_Apache Camel Developer's Cookbook, 2nd Edition_](http://www.packtpub.com/apache-camel-developers-cookbook/book)
(Packt Publishing, TBD 2017) by [Scott Cranton](https://github.com/scranton), [Jakub Korab](https://github.com/jkorab), and [Christian Posta](https://github.com/christian-posta).
The latest version of this code is available on [GitHub](http://github.com/CamelCookbook/camel-cookbook-examples).
*This project is up to date with [Apache Camel 2.20.0](http://camel.apache.org/camel-2200-release.html).*
All of the examples are driven through JUnit tests, and are collectively structured as a set
of Apache Maven projects. To execute them, you will need a copy of the [Java 8 JDK](http://openjdk.java.net/install/)
and an [Apache Maven 3](http://maven.apache.org/) installation.
Maven will download all of the appropriate project dependencies.
In order to execute all the tests, all you need to do is run:
$ mvn clean install

Examples for Learning Spark
===============
Examples for the Learning Spark book. These examples require a number of libraries and as such have long build files. We have also added a stand alone example with minimal dependencies and a small build file
in the mini-complete-example directory.
These examples have been updated to run against Spark 1.3 so they may
be slightly different than the versions in your copy of "Learning Spark".
Requirements
==
* JDK 1.7 or higher
* Scala 2.10.3
- scala-lang.org
* Spark 1.3
* Protobuf compiler
- On debian you can install with sudo apt-get install protobuf-compiler
* R & the CRAN package Imap are required for the ChapterSixExample
* The Python examples require urllib3
Python examples
===
From spark just run ./bin/pyspark ./src/python/[example]
Spark Submit
===
You can also create an assembly jar with all of the dependencies for running either the java or scala
versions of the code and run the job with the spark-submit script
./sbt/sbt assembly OR mvn package
cd $SPARK_HOME; ./bin/spark-submit --class com.oreilly.learningsparkexamples.[lang].[example] ../learning-spark-examples/target/scala-2.10/learning-spark-examples-assembly-0.0.1.jar

==========================
[](https://ge.spring.io/scans?search.rootProjectNames=spring-integration-samples)
Welcome to the **Spring Integration Samples** repository which provides **50+ samples** to help you learn [Spring Integration][]. To simplify your experience, the *Spring Integration* samples are split into 4 distinct categories:
* Basic
* Intermediate
* Advanced
* Applications
* DSL
Inside of each category you'll find a **README.md** file, which will contain a more detailed description of that category. Each sample also comes with its own **README.md** file explaining further details, e.g. how to run the respective sample.
| For additional samples, please also checkout the [Spring Integration Extensions][] project as it also provides numerous samples.
*Happy Integration!*
# Note
This (main) branch requires Spring Integration 6.0 or above.
For samples running against earlier versions of Spring Integration, use the __5.5.x__ and other branches.
The project requires now Java 17 or above.
To open the project in the IDE, use its `import` option against a `build.gradle` file from the root project directory.
## Related GitHub projects

* [Spring Integration Extensions][]
## Community Sample Projects
* [Xavier Padró][]
# Categories
Below is a short description of each category.
## DSL
This directory holds demos/samples for Spring Integration 4.0 Java Configuration as well as the Java DSL Extension.
## Basic
This is a good place to get started. The samples here are technically motivated and demonstrate the bare minimum with regard to configuration and code to help you to get introduced to the basic concepts, API and configuration of Spring Integration. For example, if you are looking for an answer on how to wire a **Service Activator** to a **Channel** or how to apply a **Gateway** to your message exchange or how to get started with using the **MAIL** or **XML** module, this would be the right place to find a relevant sample. The bottom line is that this is a good starting point.
* **amqp** - Demonstrates the functionality of the various **AMQP Adapters**
* **barrier** - Shows how to suspend a thread until some asynchronous event occurs
* **control-bus** - Demonstrates the functionality of the **Control Bus**
* **enricher** - This sample demonstrates how the Enricher components can be used
* **feed** - Demonstrates the functionality of the **Feed Adapter** (RSS/ATOM)
* **file** - Demonstrates aspects of the various File Adapters (e.g. **File Inbound/Outbound Channel Adapters**, file **polling**)

* **tcp-broadcast** - Demonstrates broadcasting a message to multiple connected TCP clients.
* **tcp-client-server** - Demonstrates socket communication using **TcpOutboundGateway**, **TcpInboundGateway** and also uses a **Gateway** and a **Service Activator**
* **tcp-with-headers** - Demonstrates sending headers along with the payload over TCP using JSON.
* **testing-examples** - A series of test cases that show techniques to **test** Spring Integration applications.
* **twitter** - Illustrates Twitter support using the **Twitter Inbound Channel Adapter**, **Twitter Inbound Search Channel Adapter**, **Twitter Outbound Channel Adapter**
* **ws-inbound-gateway** - Example showing basic functionality of the **Web Service Gateway**

* **xml** - Example demonstrates various aspects of the **Xml** support using an **XPath Splitter**, **XPath Router**, **XSLT Transformer** as well as **XPath Expression** support
* **xmpp** - Show the support for [**XMPP**](https://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol) (formerly known as Jabber) using e.g. GoogleTalk
## Intermediate
This category targets developers who are already more familiar with the Spring Integration framework (past getting started), but need some more guidance while resolving more advanced technical problems that you have to deal with when switching to a Messaging architecture. For example, if you are looking for an answer on how to handle errors in various scenarios, or how to properly configure an **Aggregator** for the situations where some messages might not ever arrive for aggregation, or any other issue that goes beyond a basic understanding and configuration of a particular component to address "what else you can do?" types of problems, this would be the right place to find relevant examples.
* **async-gateway** - Usage example of an asynchronous **Gateway**
* **dynamic-poller** - Example shows usage of a **Poller** with a custom **Trigger** to change polling periods at runtime
* **async-gateway** - Example shows usage of an **Asynchronous Gateway**
* **errorhandling** - Demonstrates basic **Error Handling** capabilities of Spring Integration
* **file-processing** - Sample demonstrates how to wire a message flow to process files either sequentially (maintain the order) or concurrently (no order).
* **mail-attachments** - Demonstrates the processing of email attachments
* **monitoring** The project used in the *[Spring Integration Management and Monitoring Webinar](https://www.springsource.org/node/3598)* Also available on the *[SpringSourceDev YouTube Channel](https://www.youtube.com/SpringSourceDev)*
* **multipart-http** - Demonstrates the sending of HTTP multipart requests using Spring's **RestTemplate** and a Spring Integration **Http Outbound Gateway**
* **rest-http** - This sample demonstrates how to send an HTTP request to a Spring Integration's HTTP service while utilizing Spring Integration's new HTTP Path usage. This sample also uses Spring Security for HTTP Basic authentication. With HTTP Path facility, the client program can send requests with URL Variables.
* **retry-and-more** Provides samples showing the application of MessageHandler Advice Chains to endpoints - retry, circuit breaker, expression evaluating
* **splitter-aggregator-reaper** A demonstration of implementing the Splitter and Aggregator *Enterprise Integration Patterns* (EIP) together. This sample also provides a concrete example of a [message store reaper][] in action.
* **stored-procedures-derby** Provides an example of the stored procedure Outbound Gateway using *[Apache Derby](https://db.apache.org/derby/)*
* **stored-procedures-ms** Provides an example of the stored procedure Outbound Gateway using *Microsoft SQL Server*
* **stored-procedures-oracle** Provides an example of the stored procedure Outbound Gateway using *ORACLE XE*
* **stored-procedures-postgresql** Provides an example of the stored procedure Outbound Gateway using *[PostgreSQL](https://www.postgresql.org/)*
* **tcp-async-bi-directional** - Demonstrates the use of *Collaborating Channel Adapters* for arbitrary async messaging (not request/reply) between peers.
* **tcp-client-server-multiplex** - Demonstrates the use of *Collaborating Channel Adapters* with multiple in-flight requests/responses over a single connection.
* **travel** - More sophisticated example showing the retrieval of weather (SOAP Web Service) and traffic (HTTP Service) reports using real services
* **tx-synch** Provides a sample demonstrating the use of transaction synchronization, renaming an input file to a different filename, depending on whether the transaction commits, or rolls back.
## Advanced
This category targets advanced developers who are quite familiar with Spring Integration but are looking to address a specific custom need by extending the Spring Integration public API. For example, if you are looking for samples showing how to implement a custom **Channel** or **Consumer** (event-based or polling-based), or you are trying to figure out what is the most appropriate way to implement a custom **BeanParser** on top of the Spring Integration BeanParser hierarchy when implementing a custom namespace, this would be the right place to look. Here you can also find samples that will help you with adapter development. Spring Integration comes with an extensive library of adapters that allow you to connect remote systems with the Spring Integration messaging framework. However you might have a need to integrate with a system for which the core framework does not provide an adapter, so you have to implement your own. This category would include samples showing you how to implement various adapters.
* **advanced-testing-examples** - Example test cases that show advanced techniques to test Spring Integration applications
* **dynamic-ftp** - Demonstrates one technique for sending files to dynamic destinations.
* **dynamic-tcp-client** - Demonstrates a technique for dynamically creating TCP clients.
## Applications
This category targets developers and architects who have a good understanding of Message-Driven architecture and Enterprise Integration Patterns, and have an above average understanding of Spring and Spring integration and who are looking for samples that address a particular business problem. In other words, the emphasis of samples in this category is '**business use cases**' and how they can be solved via a Messaging architecture and Spring Integration in particular. For example, if you are interested to see how a Loan Broker process or Travel Agent process could be implemented and automated via Spring Integration, this would be the right place to find these types of samples.
* **cafe** - Emulates a simple operation of a coffee shop combining various Spring Integration adapters (Including **Router** and **Splitter**) see [Appendix A of the reference documentation](https://docs.spring.io/spring-integration/docs/current/reference/html/#samples) for more details. Implementations are provided for:
- AMQP
- JMS
- In memory channels
* **cafe-scripted** - Scripted implementation of the classic **cafe** sample application. Supports **JavaScript**, **Groovy**, **Ruby**, and **Python**.
* **loan-broker** - Simulates a simple banking application (Uses **Gateway**, **Chain**, **Header Enricher**, **Recipient List Router**, **Aggregator**) see [Appendix A of the reference documentation](https://docs.spring.io/spring-integration/docs/current/reference/html/#samples) for more details
* **loanshark** This extension to the loan broker sample shows how to exchange messages between Spring Integration applications (and other technologies) using **UDP**.
**file-split-ftp** - Reads a file; splits into 3 based on contents; sends files over ftp; sends email with results.

- Using gradle - passing main class to run on the command line
- Using Maven - configuring the main class inside the pom.xml
Some of these are covered in more detail below.
### Run the Examples in IntelliJ Idea(needs pre-downloaded javafx modules)
To run the examples from within IntelliJ IDEA you must first create a new project in IntelliJ, and set the root
directory to the directory into which you have cloned this Git repository.
Second, you must download JavaFX and unzip the distribution to some directory.
Third, you must add all the JAR files found in the "lib" directory to your project's classpath.
Fourth, you must create a run configuration for the example class you want to run. Add the following
JVM args to that run configuration:
--module-path C:\data\downloads\javafx\javafx-sdk-14\lib --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web
Make sure that the --module-path points to the directory you unzipped your downloaded JavaFX distribution to (meaning the "lib" dir within that JavaFX distribution dir - as shown above).
### Run in IDE - alternative
Instead of creating run configuration for each example class you can create a run configuration for the ExampleRunner class(based on maven or gradle nature. Both are supported using wrappers so you don't need to have any of them on you system and you can choose to use the one you prefer), and then from inside the
ExampleRunner class, call the example class you want to run - by changing the main() method inside the ExampleRunner class. For instance,
add the following line to the ExampleRunner class main() method and then run ExampleRunner main
ButtonExample.main(args);
### Run via Maven - Passing Main Class as Argument to Maven
You can use maven and pass the example class you want to add. for example to run WebViewExample you can run
./mvnw compile exec:java -Dexec.args="com.jenkov.javafx.webview.WebViewExample"
### Run via Gradle - Passing Main Class as Argument to Gradle
You can use gradle and pass the example class you want to add. for example to run WebViewExample you can run
./gradlew run --args="com.jenkov.javafx.webview.WebViewExample"
### Run via Maven
You can use Maven and edit the pom.xml file and change "mainClass" of openjfx plugin configuration and select the example you want then run
./mvnw clean javafx:run

in28minutes/MavenIn28Minutes | Maven Tutorial for Beginners with Examples | null | # Maven Tutorial for Beginners - with Examples In28Minutes
[](https://www.udemy.com/course/learn-maven-java-dependency-management-in-20-steps/)
## Installing Eclipse and Java
https://github.com/in28minutes/SpringIn28Minutes/blob/master/InstallationGuide-JavaEclipseAndMaven_v2.pdf
## Course Overview
- We will use Handson Real World Examples to understand what Maven can do.
- We will understand how Maven makes the life of an application developer easy.
- We will learn how Maven helps us to automate things like compilation, running unit tests, creating a war, creating an ear, running a web application in tomcat.
- We will learn how to use Maven effectively in combination of an IDE like Eclipse.
- We will use
- Maven for dependency management, building and running the application in tomcat.
- Eclipse IDE.
### Step List
Lets now look at the steps in this tutorial.
- Step 1 to 4 we will learn about the basics of Maven : Project Object Model and Build LifeCycle
- Steps 5 and 6 we will learn about dependency management and transitive dependencies
- Step 7 we will learn about a maven project with multiple layers. Typical projects have a web layer, data layer, external interface layer. We will learn how to create such projects using maven. Multi Module Maven Project.
- Step 8 : We will learn how to create a war, deploy to tomcat.
### Running Examples
- If you are downloading the zip file, unzip the file
- Open Command Prompt and Change directory to folder containing pom.xml
- Run command "mvn tomcat7:run"
- For help : user our installation guide - https://github.com/in28minutes/SpringIn28Minutes/blob/master/InstallationGuide-JavaEclipseAndMaven_v2.pdf
### Youtube Video

# 0. What is Maven?
Defining what Maven does is very difficult.
## Every Day Developer
Manages Dependencies - Web Layer (Spring MVC), Data Layer (JPA - Hibernate) etc..
Build a jar or a war or an ear
Run the application locally - Tomcat or Jetty
Deploy to a T environment
Add new dependencies to a project
Run Unit Tests
## Maven helps us do all these and more...
Generate Projects
Create Eclipse Workspace
# 1. Beginner Maven Project
## What is the power of Maven?
#### First Project : My aim is to create a Spring.jar. Think as if you are developing Spring. Some other developers want to use the framework you are developing. Steps in creating a JAr
- App.Java -> App.class
- AppTest.Java -> AppTest.class
- Run Unit Tests
- Package in a particular format
- Earlier this was done using long tedious ant scripts
#### Convention over Configuration
- Pre defined folder structure
- pom.xml
- mvn --version
- mvn compile (compiles source files)
- mvn test-compile (compiles test files) - one thing to observe is this also compiles source files
- mvn clean - deletes target directory
- mvn test - run unit tests
## You are ready for theory on Build Life Cycle
Pre-defined sequence of steps that are done when we run a maven command. Plugins can be attached to lifecycle stages. Default plugins are already defined in the super pom.
mvn install
- package - creates the jar
- install - copies the created jar to local maven repository - a temp folder on my machine where maven stores the files.
### Build LifeCycle
Validate
Compile
Test
Package
Integration Test
Verify
Install
Deploy
## Lets understand pom.xml
### Project Object Model (POM)
Name (if another project want to refer to our project, how do they do it?)
Version (Major Version, Minor Version, Incremental Version)
Packaging
Dependencies
Plugins
### Maven repository stores all the versions of all dependencies. JUnit 4.2,4.3,4.4
### Local Repository - all the dependencies that are downloaded for 1st time are stored.
# 2. Intermediate Maven Project
- Transtive Dependencies (add Hibernate dependency)
- Exclusions - Add an exclude
- Dependency Hierarchy - See how each dependency is coming in
- Versions [4.1,] [,4.1] [,4.1)
- Scope - Dependencies are needed only for tests. They are not part of the war or jar. we can use scope for that.
- Maven Compiler Plugin - Change source from 1.5 to 1.8.
- Effective Pom - Super Pom (Similar to Java Inheritance) - Check the build part of super pom (Convention over configuration - defaults are defined). We can change it - for example source directory. Recommended not to override defaults. Easy to move from one project to another project. Definitions of various plugins. mvn help:effective-pom

## Build Status @ Travis CI ##
[](https://travis-ci.org/ttrelle/spring-data-examples)
## Usage
The projects are using a Maven based build. To run the tests on the command line use
mvn clean test
If you want to use an IDE like Eclipse run
mvn eclipse:eclipse
and set the Eclipse variable M2_REPO pointing to your local Maven repository. Or just import the project as an existing Maven project if you are using the m2 plugin.

swagger-api/swagger-core | Examples and server integrations for generating the Swagger API Specification, which enables easy access to your REST API | java open-source openapi openapi-specification openapi3 rest rest-api swagger swagger-api swagger-oss | # Swagger Core <img src="https://raw.githubusercontent.com/swagger-api/swagger.io/wordpress/images/assets/SW-logo-clr.png" height="50" align="right">
**NOTE:** If you're looking for Swagger Core 1.5.X and OpenAPI 2.0, please refer to [1.5 branch](https://github.com/swagger-api/swagger-core/tree/1.5).
**NOTE:** Since version 2.1.7, Swagger Core also supports the Jakarta namespace. There are a parallel set of artifacts with the `-jakarta` suffix, providing the same functionality as the unsuffixed (i.e.: `javax`) artifacts.
Please see the [Wiki](https://github.com/swagger-api/swagger-core/wiki/Swagger-2.X---Getting-started) for more details.
**NOTE:** Since version 2.2.0 Swagger Core supports OpenAPI 3.1; see [this page](https://github.com/swagger-api/swagger-core/wiki/Swagger-2.X---OpenAPI-3.1) for details
[](https://maven-badges.herokuapp.com/maven-central/io.swagger.core.v3/swagger-project)
Swagger Core is a Java implementation of the OpenAPI Specification. Current version supports *JAX-RS2* (`javax` and `jakarta` namespaces).
## Get started with Swagger Core!
See the guide on [getting started with Swagger Core](https://github.com/swagger-api/swagger-core/wiki/Swagger-2.X---Getting-started) to get started with adding Swagger to your API.
## See the Wiki!
The [github wiki](https://github.com/swagger-api/swagger-core/wiki) contains documentation, samples, contributions, etc. Start there.
## Compatibility
The OpenAPI Specification has undergone several revisions since initial creation in 2010. The Swagger Core project has the following compatibilities with the OpenAPI Specification:

write2munish/Akka-Essentials | Java/Scala Examples from the book - Akka Essentials | actors akka java remote-actors scala supervisor testkit | Akka Essentials
(refer http://akka-essentials.blogspot.com/ for more details)
[](https://api.travis-ci.org/write2munish/Akka-Essentials)
You will find examples of Akka in Java & Scala, talking of one concept along with a problem solved
ClientServerExample : This example demonstrates how the remote actors works in a client / server mode. The client sends the message to the server and server replies back to the client. The example also demonstrates various methods of creating remote actor references on the client side.
LoadGeneratorExample : This example generates 10 million messages and calculates the time it takes to process them. The program demonstrated the Routing concept where a roundrobinrouter is used to distribute the load on to a set of workers
WordCountMapReduce : This examples implements the Word Count Map Reduce model. The client system reads a text file and sends each line of text as a message to the Server. The server reads the line, maps the words, reduces the words and finally does an inmemory aggregation of the result. The example also implemented a prioritymailbox, which is used to segregate the message requests between the mapreduce requests and getting the list of results from the aggregate actor
GridPatternExample : Grid Computing pattern is where a control node distributes the work to other nodes. Idea is to make use of the nodes on the network for their computing power. It is analogous to Master Slave Pattern with certain differences. The idea behind the Master Slave pattern is to partition the work into identical sub tasks which are then delegated to Slaves. The example demonstrates how an WorkerActor system sends a request for registration. The RegisterRemoteWorker recieves the request and forwards the same to JobController where the RoundRobinRouter is updated for the new worker information. The WorkScheduler sends a periodic request to JobController, who then sends packets to all the registered worker actors.
AkkaSerializableExample : Akka by default supports 2 serializer options - java and protobuf. In addition, Akka provides an API to write you owns serializable. In this example, i have used google gson library to convert your value object into json string representation which is then converted to bytes and transported across the wire
AkkaSupervisorExample : Akka provides two supervisor strategies - One-For-One or All-For-One that are used to monitor the actors and build the fault tolerance in the actor model. There are 3 examples that demonstrate the strategies and their usage. In addition, the java section has unit testing code also for testing your supervisor code
AkkaWithZeroMQ - Akka provides native support for ZeroMQ libraries and provide different connectors (Pub-Sub, Req-Rep,Router-Dealer and Pull-Push). There are four examples that demonstrated their usage
AkkaUnitTest : Unit testing toolkit is provided via TestKit in Akka. The scala side of unit testing is well covered. For java, TestKit provides limited constructs. The various examples implemented by Ray Roestenburg have ported to Java world, with couple of more scenario's added. This can be good starting point for Java programmers to start unit testing their actors
AkkaPersistentExample : Akka provides persistent model for stateful actors. The example uses a simple example of Integer (which carries the ) and operations (ADD, SUBTRACT, MULTIPLY, DIVIDE) along with operand acts on the state object

hamvocke/spring-testing | A Spring Boot application with lots of test examples | microservices spring spring-boot spring-test tdd test-automation test-microservices test-pyramid testing | # The Practical Test Pyramid: Spring Boot Edition
[](https://circleci.com/gh/hamvocke/spring-testing/tree/master)
This repository contains a *Spring Boot* application with lots of test examples on different levels of the [Test Pyramid](https://martinfowler.com/bliki/TestPyramid.html). It shows an opinionated way to thoroughly test your spring application by demonstrating different types and levels of testing. You will find that some of the tests are duplicated along the test pyramid -- concepts that have already been tested in lower-level tests will be tested in more high-level tests. This contradicts the premise of the test pyramid. In this case it helps demonstrating different kinds of tests which is the main goal of this repository.
## Read the Blog Post
This repository is part of a [blog posts](https://martinfowler.com/articles/practical-test-pyramid.html) I wrote about test automation and the test pyramid. I highly recommend you read it to get a better feeling for the purpose of the different kinds of tests in this repository and how you can implement a reliable test suite for a Spring Boot application.
## Get started
### 1. Set an API Key as Environment Variable
In order to run the service, you need to set the `WEATHER_API_KEY` environment variable to a valid API key retrieved from ~~darksky.net~~ [openweathermap.org](https://openweathermap.org/).
_Note: in a previous version this example used darksky.net as the weather API. Since they've shut down their API for public access, we've since switched over to openweathermap.org_
A simple way is to rename the `env.sample` file to `.env`, fill in your API key from _openweathermap.org_ and source it before running your application:
```bash
source .env
```
### 2. Start a PostgreSQL database
The easiest way is to use the provided `startDatabase.sh` script. This script starts a Docker container which contains a database with the following configuration:
* port: `15432`
* username: `testuser`
* password: `password`
* database name: `postgres`
If you don't want to use the script make sure to have a database with the same configuration or modify your `application.properties`.
### 3. Run the Application
Once you've provided the API key and started a PostgreSQL database you can run the application using
```bash
./gradlew bootRun
```
The application will start on port `8080` so you can send a sample request to `http://localhost:8080/hello` to see if you're up and running.
## Application Architecture
```
╭┄┄┄┄┄┄┄╮ ┌──────────┐ ┌──────────┐
┆ ☁ ┆ ←→ │ ☕ │ ←→ │ 💾 │
┆ Web ┆ HTTP │ Spring │ │ Database │
╰┄┄┄┄┄┄┄╯ │ Service │ └──────────┘
└──────────┘
↑ JSON/HTTP
↓
┌──────────┐
│ ☁ │
│ Weather │
│ API │
└──────────┘
```
The sample application is almost as easy as it gets. It stores `Person`s in an in-memory database (using _Spring Data_) and provides a _REST_ interface with three endpoints:
* `GET /hello`: Returns _"Hello World!"_. Always.
* `GET /hello/{lastname}`: Looks up the person with `lastname` as its last name and returns _"Hello {Firstname} {Lastname}"_ if that person is found.
* `GET /weather`: Calls a downstream [weather API](https://openweathermap.org/current#name) via HTTP and returns a summary for the current weather conditions in Hamburg, Germany
### Internal Architecture
The **Spring Service** itself has a pretty common internal architecture:
* `Controller` classes provide _REST_ endpoints and deal with _HTTP_ requests and responses
* `Repository` classes interface with the _database_ and take care of writing and reading data to/from persistent storage
* `Client` classes talk to other APIs, in our case it fetches _JSON_ via _HTTP_ from the openweathermap.org weather API
```
Request ┌────────── Spring Service ───────────┐
─────────→ ┌─────────────┐ ┌─────────────┐ │ ┌─────────────┐
←───────── │ Controller │ ←→ │ Repository │←──→ │ Database │
Response │ └─────────────┘ └─────────────┘ │ └─────────────┘
│ ↓ │
│ ┌──────────┐ │
│ │ Client │ │
│ └──────────┘ │
└─────────│───────────────────────────┘
│
↓
┌──────────┐
│ ☁ │
│ Weather │
│ API │
└──────────┘
```
## Test Layers
The example applicationn shows different test layers according to the [Test Pyramid](https://martinfowler.com/bliki/TestPyramid.html).
```
╱╲
End-to-End
╱────╲
╱ Inte-╲
╱ gration╲
╱──────────╲
╱ Unit ╲
──────────────
```
The base of the pyramid is made up of unit tests. They should make the biggest part of your automated test suite.
The next layer, integration tests, test all places where your application serializes or deserializes data. Your service's REST API, Repositories or calling third-party services are good examples. This codebase contains example for all of these tests.
```
╭┄┄┄┄┄┄┄╮ ┌──────────┐ ┌──────────┐
┆ ☁ ┆ ←→ │ ☕ │ ←→ │ 💾 │
┆ Web ┆ │ Spring │ │ Database │
╰┄┄┄┄┄┄┄╯ │ Service │ └──────────┘
└──────────┘
│ Controller │ Repository │
└─── Integration ───┴──── Integration ─────┘
│ │
└────────────── Acceptance ────────────────┘
```
```
┌─────────┐ ─┐
│ ☁ │ │
│ Weather │ │
│ API │ │
│ Stub │ │
└─────────┘ │ Client
↑ │ Integration
↓ │ Test
┌──────────┐ │
│ ☕ │ │
│ Spring │ │
│ Service │ │
└──────────┘ ─┘
```
## Tools
You can find lots of different tools, frameworks and libraries being used in the different examples:
* **Spring Boot**: application framework
* **JUnit**: test runner
* **Hamcrest Matchers**: assertions
* **Mockito**: test doubles (mocks, stubs)
* **MockMVC**: testing Spring MVC controllers
* **RestAssured**: testing the service end to end via HTTP
* **Wiremock**: provide HTTP stubs for downstream services

rathboma/hadoop-framework-examples | An implementation of a real-world map-reduce workflow in each major framework. | null | # Realistic Hadoop Data Processing Examples
This code is to accompany [my blog post on map reduce frameworks][1]
The point of the code in this repository is to provide an implementation for a business question (listed below) in each of the major Map Reduce frameworks.
Each implementation will get it's own subdirectory with it's own build and running instructions. Each framework will also get an accompanying test, and an in-depth walkthrough about implementation details.
The following implementations are complete:
* Java map reduce - [walkthrough](http://blog.matthewrathbone.com/2013/02/09/real-world-hadoop-implementing-a-left-outer-join-in-hadoop-map-reduce.html)
* Scoobi - [walkthrough](http://blog.matthewrathbone.com/2013/11/03/real-world-hadoop---implementing-a-left-outer-join-with-scoobi.html)
* Scalding - [walkthrough](http://blog.matthewrathbone.com/2015/10/20/2015-10-20-scalding-tutorial.html)
* Cascading - [walkthrough](http://blog.matthewrathbone.com/2015/06/25/real-world-hadoop---implementing-a-left-outer-join-in-java-with-cascading.html)
* Hive - [walkthrough](http://blog.matthewrathbone.com/2013/02/20/real-world-hadoop---implementing-a-left-outer-join-in-hive.html)
* Pig - [walkthrough](http://blog.matthewrathbone.com/2013/04/07/real-world-hadoop---implementing-a-left-outer-join-in-pig.html)
## The problem
### The Data
We have two datasets: customers, and transactions.
Customer Fields:
* id (1)
* email (matthew@example.com)
* language (EN)
* location (US)
Transaction Fields:
* transaction-id (1)
* product-id (1)
* user-id (1)
* purchase-amount (19.99)
* product-description (a rubber chicken)
These two datasets are stored in tab-delimited files somewhere on HDFS.
### The Question
For each product, we want to know the number of locations in which that product was purchased.
That's it!
In the real world, we might have other questions, like the number of purchases per location for each product.

devunwired/recyclerview-playground | Examples of RecyclerView use and custom LayoutManager implementations | null | Android RecyclerView Examples
-----------------------------
This repository contains examples for using the RecyclerView widget found in the Android Support Library.
Disclaimer
----------
This repository contains sample code intended to demonstrate the capabilities of the RecyclerView layout manager APIs. It is not intended to be used as-is in applications as a library dependency, and will not be maintained as such. Bug fix contributions are welcome, but issues and feature requests will not be addressed.
Example Contents
----------------
The following bits can be found in the main sample application:
- Implementation of `LinearLayoutManager` and `GridLayoutManager` for vertical and horizontal scrolling.
- Custom ItemDecorations
- `InsetDecoration` - Create an inset margin on all child views.
- `DividerDecoration` - Create an inset margin and draw dividers below vertical child views.
- `GridDividerDecoration` - Create an inset margin an draw dividers along grid lines
- Custom LayoutManager
- `FixedGridLayoutManager` - Similar to `StaticGridLayoutManager`, but with a controllable column count.
The following examples are incubating on the `experimental` branch (these mostly work, if you feel like living dangerously):
- Custom LayoutManagers
- `StaticGridLayoutManager` - 2D scrolling grid with variable column count based on data set. Window of visible (non-recycled) views is determined statically.
- `DynamicGridLayoutManager` - 2D scrolling grid where window of visible views is determined dynamically. Results in fewer views in memory, but scrolling performance is questionable.

TNG/ArchUnit-Examples | Examples for ArchUnit (A Java architecture test library, to specify and assert architecture rules in plain Java) | null | # ArchUnit Examples
This module presents some examples on how to use the latest release of
[ArchUnit](http://archunit.org).
The different subprojects demonstrate the type of test support:
* `example-junit4` shows how to use the JUnit 4 test support including the `ArchUnitRunner`
* `example-junit5` shows how to use the JUnit 5 test support where test classes are simply being picked up by being annotated with `@AnalyzeClasses`
* `example-plain` shows how to use ArchUnit independently of any specific test framework, even though as a runtime environment these tests use JUnit 4 as well
All example rules you find within `src/test` refer to classes from `src/main`.
These tests are all designed to fail, to demonstrate how production code could violate
typical architectural constraints (like layer dependencies).
You can run them with Gradle
```
./gradlew build
```
Otherwise the tests can be run directly from any IDE.
## Regarding issues
If you have found any issues with the examples or have any question, please direct them to the [main repository](https://github.com/TNG/ArchUnit/issues) instead. This repository is an autogenerated version of the latest released version of https://github.com/TNG/ArchUnit/tree/main/archunit-example (with some simplified project setup for illustration)

[](https://github.com/gothinkster/spring-boot-realworld-example-app/actions)
> ### Spring boot + MyBatis codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the [RealWorld](https://github.com/gothinkster/realworld-example-apps) spec and API.
This codebase was created to demonstrate a fully fledged full-stack application built with Spring boot + Mybatis including CRUD operations, authentication, routing, pagination, and more.
For more information on how to this works with other frontends/backends, head over to the [RealWorld](https://github.com/gothinkster/realworld) repo.
# *NEW* GraphQL Support
Following some DDD principles. REST or GraphQL is just a kind of adapter. And the domain layer will be consistent all the time. So this repository implement GraphQL and REST at the same time.
The GraphQL schema is https://github.com/gothinkster/spring-boot-realworld-example-app/blob/master/src/main/resources/schema/schema.graphqls and the visualization looks like below.
And this implementation is using [dgs-framework](https://github.com/Netflix/dgs-framework) which is a quite new java graphql server framework.
# How it works
The application uses Spring Boot (Web, Mybatis).
* Use the idea of Domain Driven Design to separate the business term and infrastructure term.
* Use MyBatis to implement the [Data Mapper](https://martinfowler.com/eaaCatalog/dataMapper.html) pattern for persistence.
* Use [CQRS](https://martinfowler.com/bliki/CQRS.html) pattern to separate the read model and write model.
And the code is organized as this:
1. `api` is the web layer implemented by Spring MVC
2. `core` is the business model including entities and services
3. `application` is the high-level services for querying the data transfer objects
4. `infrastructure` contains all the implementation classes as the technique details
# Security
Integration with Spring Security and add other filter for jwt token process.
The secret key is stored in `application.properties`.
# Database
It uses a ~~H2 in-memory database~~ sqlite database (for easy local test without losing test data after every restart), can be changed easily in the `application.properties` for any other database.
# Getting started
You'll need Java 11 installed.
./gradlew bootRun
To test that it works, open a browser tab at http://localhost:8080/tags .
Alternatively, you can run
curl http://localhost:8080/tags
# Try it out with [Docker](https://www.docker.com/)
You'll need Docker installed.
./gradlew bootBuildImage --imageName spring-boot-realworld-example-app
docker run -p 8081:8080 spring-boot-realworld-example-app
# Try it out with a RealWorld frontend
The entry point address of the backend API is at http://localhost:8080, **not** http://localhost:8080/api as some of the frontend documentation suggests.
# Run test
The repository contains a lot of test cases to cover both api test and repository test.
./gradlew test
# Code format
Use spotless for code format.
./gradlew spotlessJavaApply
# Help
Please fork and PR to improve the project.

# Event Sourcing and CQRS Examples
This project aims to provide examples of how to use Event Sourcing and CQRS applied to a minimalistic bank context.
We assume the reader has basic knowledge of Event Sourcing and CQRS concepts.
If you want to brush up on the subject we suggest reading:
- [https://martinfowler.com/eaaDev/EventSourcing.html](https://martinfowler.com/eaaDev/EventSourcing.html)
- [https://martinfowler.com/bliki/CQRS.html](https://martinfowler.com/bliki/CQRS.html)
## Domain overview
In this minimalistic bank, a _client_ can _open_ one or more _accounts_.
On each _account_, the _client_ can _deposit_ or _withdraw_ money.
The history of an _account's transactions_ is available to the _client_ as well as a summary of the _client's accounts_.
## Design choices
### Architecture overview

+-------------------------+
#### Ports and Adapters
For the Domain Model, we chose the Ports and Adapters structure because we wanted to protect the domain logic from
all the technical concerns.
For more information about it read [here](http://www.dossier-andreas.net/software_architecture/ports_and_adapters.html).
#### Package by Feature
For the Read Models, we chose the Package by Feature structure because we would not benefit from isolating the layers
and instead we put all feature related parts close together.
For more information about it read [here](http://www.javapractices.com/topic/TopicAction.do?Id=205).
### DDD and REST
There has been a myth of DDD and REST being incompatible due to DDD being all about behaviour
whereas REST is all about state.
In this project we followed both techniques quite strictly and hope that the result shows that they can be well combined.
Note: We did not include REST hypermedia controls as we believe it is a big subject in itself and didn't want to shift focus from Event Sourcing and CQRS.
### Event Sourcing and CQRS (finally!)
We have taken a pragmatic approach when combining Event Sourcing and CQRS.
By the book, CQRS proposes a complete separation between the read/query and write/command sides,
but that's not what we have here.
The approach we've taken instead:
- The writes/commands are all on the domain model side and processed by aggregates;
- The reads/queries are both in the domain model side and in the read model side.
- The queries in the domain model side are only allowed when the data we need is a single aggregate itself.
The reason being that we can only query the event store by aggregate id
and we can actually fulfill those queries by replaying that single aggregate events.
- For any other kind of query, we don't want to compromise the domain model.
Therefore, we create read models to fulfill those queries.
They are basically projections, potentially built from different events and aggregates
that can be queried by more appropriate fields.
#### Events
Events are a thing from the past. It communicates a significant change that _happened_.
##### Idempotency when replaying events
When replaying events, we don't want to execute any business logic because we can't change history. We only want to do assignments.
A simple example is with a deposit event: instead of adding the deposited amount to the balance when replaying (business logic), we want
the updated balance already available so that we can just assign it. This makes it possible to replay the event multiple times with the same outcome.
##### Ordering of events
In a distributed world, event timestamps are unreliable for ordering - machines have their own clocks.
Instead we can make the ordering explicit with an event version.
In this project we use event versioning in two ways:
- In the write/command side, we use it for protecting ourselves from race conditions via optimistic locking;
- In the read/query side, we use it for commutative reasons, meaning events can come out of order and we can still handle them properly.
If you are interested in this topic, we also recommend reading about [Lamport timestamps](https://en.wikipedia.org/wiki/Lamport_timestamps) and [Vector clocks](https://en.wikipedia.org/wiki/Vector_clock) as alternatives.
## Trying it out
### Requirements
- Java 14
- Maven
### Building the application
` mvn clean verify `
### Starting the application
` java -jar target/bank-service-1.0-SNAPSHOT.jar server src/environments/development.yml `
### Examples of use
#### Create a client
` curl -v -X POST -H "Content-Type: application/json" -d '{"name":"Jane Doe", "email":"jane.doe@example.com"}' http://localhost:8080/clients `
Check the created client in the response's 'Location' header.
#### Create an account for the client
` curl -v -X POST -H "Content-Type: application/json" -d '{"clientId":"{CLIENT_ID}"}' http://localhost:8080/accounts `
Check the created account in the response's 'Location' header.
#### Make a deposit to the account
` curl -v -X POST -H "Content-Type: application/json" -d '{"amount":1000000}' http://localhost:8080/accounts/{ACCOUNT_ID}/deposits `
#### Check that you created a millionaire!
` curl -v http://localhost:8080/accounts/{ACCOUNT_ID} `
#### More operations
Go ahead and check the code! :)

centic9/jgit-cookbook | Provides examples and code snippets for the JGit Java Git implementation | git java-git jgit jgit-cookbook | jgit-cookbook
=============
[](https://github.com/centic9/jgit-cookbook/actions)
[](https://gradleupdate.appspot.com/centic9/jgit-cookbook/status)
[](https://github.com/centic9/jgit-cookbook/tags)
Provides examples and code snippets for the [JGit](https://eclipse.org/jgit/) Java Git implementation.
The JGit framework is rich and diverse, it has two layers, a low-level _api_ and a higher-level set of _porcelain_ commands. This can be a bit intimidating at first as there are lots of classes, some of which are not relevant for most tasks.
This project tries to provide a collection of ready-to-run snippets which provide a quick start for building functionality using JGit.
Please make sure to take a look at the nicely written [introduction](http://www.codeaffine.com/2015/12/15/getting-started-with-jgit/) and also use the existing [JavaDoc](http://download.eclipse.org/jgit/site/6.8.0.202311291450-r/apidocs/) and the [User Guide](http://wiki.eclipse.org/JGit/User_Guide) as well, as they are well done and provide detailed information and a general overview of JGit respectively.
*Note: Please use sites such as http://stackoverflow.com for general questions about JGit usage, not issues in this project. Issues should be used for problems with snippets and suggestions of missing snippets. Snippets from good answers on stackoverflow can then be included here, naturally.*
#### Getting started
##### Grab it
git clone https://github.com/centic9/jgit-cookbook.git
##### Build it and create Eclipse project files
###### When using Maven
mvn dependency:sources eclipse:eclipse package
###### When using Gradle
./gradlew eclipse check
#### Run it
Each snippet is a small standalone Java application, so you can simply
import the project into your favourite IDE and execute the snippets there.
#### Currently the following snippets are available

##### GitServlet
* There is a standalone sub-project in directory [httpserver](https://github.com/centic9/jgit-cookbook/blob/master/httpserver) which
starts up a simple HTTP Git server based on the JGit GitServlet.
Just import the project in your IDE and start up the `Main` application, see the Comments in the code for more details.
Another simple way to start the sample-server is to run `./gradlew run` in the httpserver-directory.
