Jackson 2.0 with Jersey 1.12

Question

Has anybody managed to use jackson 2.0 with Jersey 1.12. It will be very interesting to know. We have to use jackson 1.9.x all over the place, just because jersey has jackson so strongly coupled. From what I see even jersey 2.0M3 is still using jackson 1.9.2. So it seems there is no point to wait for jersey team to do it in near future.

Answer 1

Custom provider works; and "official" Jackson 2.0 JSON provider project does the same, with bit more features (ability to use @JsonView annotation and a few others on resource methods).

This is one of nice things with JAX-RS: everything is modular, and adding new improved providers is very easy.

Answer 2

I've Jackson 2.0 and Jersey 1.12 in my project. I had not any problems with it, but probably reason is that I had custom Provider with some additional ObjectMapper settings. Simplified version:

import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

import com.fasterxml.jackson.databind.ObjectMapper;

@Provider
public class ObjectMapperProvider implements ContextResolver<ObjectMapper> {

    private final ObjectMapper defaultObjectMapper;

    public ObjectMapperProvider() {
        defaultObjectMapper = new ObjectMapper();
    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        return defaultObjectMapper;
    }
}

If you're trying to use JsonView with Jersey, you must use org.codehaus.jackson.map.annotate.JsonView if you use the method 2.2 on here: http://wiki.fasterxml.com/JacksonFAQJaxRs

If you want to use JsonView from com.fasterxml, you must use the general method (1) on that page.
