Order Management Application - Spring Boot Version

This is a Spring Boot conversion of the Jakarta EE Order Management application, maintaining the original JSF frontend while using Spring Boot for the backend services.

Features

• Order Management: Create, view, and delete customer orders
• Line Item Management: Add parts to orders as line items
• Part Management: Manage parts with bill of materials (BOM) relationships
• Vendor Management: Search and manage vendor information
• Vendor Part Management: Associate parts with vendors and pricing

Technology Stack

• Spring Boot 3.2.0 - Main framework
• Spring Data JPA - Data access layer
• JSF 4.0 - Web framework (maintaining original frontend)
• H2 Database - In-memory database for development
• Maven - Build tool

2. Persistence: Replaced JTA with Spring's @Transactional annotations
3. Managed Beans: Converted JSF managed beans to Spring @Component beans
4. Configuration: Replaced persistence.xml with Spring Boot's application.properties
5. Database: Added H2 database for development (replaces Payara's default datasource)

Database Schema

The application uses the same database schema as the original Jakarta EE version:

• PERSISTENCE_ORDER_PART - Parts table
• PERSISTENCE_ORDER_CUSTOMERORDER - Orders table
• PERSISTENCE_ORDER_LINEITEM - Line items table
• PERSISTENCE_ORDER_VENDOR - Vendors table
• PERSISTENCE_ORDER_VENDOR_PART - Vendor parts table

Configuration

The application is configured through application.properties:

• Database connection settings
• JPA/Hibernate configuration
• JSF configuration
• Logging levels

Development Notes

• The application automatically creates sample data on startup
• All original JSF pages and functionality are preserved
• The UI remains exactly the same as the Jakarta EE version
• Spring Boot provides embedded server, so no external application server is needed
