Dependencies

To use JSON-B in your camel routes you need to add the dependency on camel-jsonb which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

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

You have to add a dependency on the implementation of a jsonb specification.

If you want to add the Johnzon implementation and you are using maven, just add following to your pom.xml

<dependency>
  <groupId>org.apache.johnzon</groupId>
  <artifactId>johnzon-jsonb</artifactId>
  <version>x.x.x</version>
</dependency>

Spring Boot Auto-Configuration

When using json-jsonb with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

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