Jackson JSON serialization, recursion avoidance by level defining
jackson, java, json, serialization
Solution
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.
Problem
I use Jackson library for serialization of my pojo objects into `JSON` representation. For example I have class A and class B: ``` class A { private int id; private B b; constructors... getters and setters } class B { private int ind; private A a; constructors... getters and setters } ``` If I want to serialize object from class A there is certain possibility to get recursion while it is serialized. I know i can stop it by using `@JsonIgnore`. Is it possible to limit the serialization by depth-level ? For example, if the level is 2, the serialization will go this way: - serialize a, level = 0 (0 < 2 ok) - > serialize - serialize a.b, level =1 (1 < 2 ok) -> serialize - serialize a.b.a, level = 2 (2 < 2 not true) -> stop Thanks in advance.
