I have objects with fields setup like this:
@XmlElement(nillable = true)
protected Integer id;
that I send out via JAX-RS with @Produces(MediaType.APPLICATION_JSON). The json
payload ends up like this when the fields aren't set:
"id":{"@xsi.nil":"true"}
I can't change the @XmlElement on the field because another part of my system
depends on it. I want to either output:
"id" : null
or ideally not output that field at all in the json payload. I think I need
extend the built in JSONProvder and tweak it (and/or Jettison) a little bit.
How can I do that without Spring? Can someone explain a solution both in terms
of web.xml and JAXRSServerFactoryBean (unit testing)?
Thanks,
Ron
