How do I configure the date formatter through Genson/Jersey?

Question

I\'m using Jersey for my RESTful services and Genson to perform my JSON/POJO conversion. There\'s no setup for Genson, I just drop it into the classpath and it just works,

Answer 1

To configure Genson instances you can use Genson.Builder class (it is similar to Gson on this point). Then you have to inject it with Jersey.

@Component
@Provider
public class GensonProvider implements ContextResolver {
   private final Genson genson = new Genson.Builder().setDateFormat(yourDateFormat).create();

    @Override
   public Genson getContext(Class type) {
     return genson;
   }
}
