Jackson JSON serialization, recursion avoidance by level defining

Question

I use Jackson library for serialization of my pojo objects into JSON representation. For example I have class A and class B:

class A {
  privat         


        

Answer 1

I recently encountered a similar problem: Jackson - serialization of entities with birectional relationships (avoiding cycles)

So the solution is to upgrade to Jackson 2.0, and add to classes the following annotation:

@JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, 
                  property = "@id")
public class SomeEntityClass ...

This works perfectly.
