You can do this per class or globally, I believe.

For per class, try @JsonSerialize above class declaration.

For a mapper, here's one example:

ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
// do various things, perhaps:
String someJsonString = mapper.writeValueAsString(someClassInstance);
SomeClass someClassInstance = mapper.readValue(someJsonString, SomeClass.class)

The StackOverflow link below also has an example for a Spring project.

For REST with Jersey, I don't remember off the top off my head, but I believe it's similar.


Couple of links I dug up: (edited 1st link due to Codehaus shutting down).
