Here I find the solution of my question.

The only thing I need to do is to register the Jackson provider and ContextResolver to ObjectMapper..

@Provider

public class UserObjectProvider implements ContextResolver {

final ObjectMapper defaultObjectMapper;
final ObjectMapper combinedObjectMapper;

public UserObjectProvider () {
    defaultObjectMapper = createDefaultMapper();
    combinedObjectMapper = createCombinedObjectMapper();
}

@Override
public ObjectMapper getContext(Class<?> type) {
    if (type == CombinedAnnotationBean.class) {
        return combinedObjectMapper;
    } else {
        return defaultObjectMapper;
    }
}

private static ObjectMapper createDefaultMapper() {
    final ObjectMapper result = new ObjectMapper();
    result.configure(Feature.INDENT_OUTPUT, true);

    return result;
}

// ...

}

Now register your Jackson provider.

final Application application = new ResourceConfig().register(UserObjectProvider.class)
.register(JacksonFeature.class);

Thanks
