Since Camel 3.10

Jackson Avro is a Data Format which uses the Jackson library with the Avro extension to unmarshal an Avro payload into Java objects or to marshal Java objects into an Avro payload.

If you are familiar with Jackson, this Avro data format behaves in the same way as its JSON counterpart, and thus can be used with classes annotated for JSON serialization/deserialization.

from("kafka:topic").
  unmarshal().avro(JsonNode.class).
  to("log:info");

Avro Jackson Options

Usage

Configuring the SchemaResolver

Since Avro serialization is schema-based, this data format requires that you provide a SchemaResolver object that is able to look up the schema for each exchange that is going to be marshalled/unmarshalled.

You can add a single SchemaResolver to the registry, and it will be looked up automatically. Or you can explicitly specify the reference to a custom SchemaResolver.

Using custom AvroMapper

You can configure JacksonAvroDataFormat to use a custom AvroMapper in case you need more control of the mapping configuration.

If you set up a single AvroMapper in the registry, then Camel will automatic lookup and use this AvroMapper.

Dependencies

To use Avro Jackson in your Camel routes, you need to add the dependency on camel-jackson-avro, which implements this data format.

If you use Maven, you could add the following to your pom.xml, substituting the version number for the latest & greatest release.

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-jackson-avro</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
