How to serialize using @Jsonview with nested objects

Question

I have a class which holds a collection of another class.

class A{
 @JsonView(VerboseViewA.Minimal.class)
 String field1;
 @JsonView(VerboseViewA.Complete.class)
 String field2;
 @JsonView(VerboseViewA.Complete.class)
 Collection<B> bEntities;
}

class B{
   @JsonView(VerboseViewB.Minimal.class)
    String field2;
   @JsonView(VerboseViewB.Complete.class)
    String field3;
 }

When i serialize Class A using VerboseViewA.Complete, i want the collection bEntities to be serialized using VerboseViewB.Minimal.

Is there a way to achieve it?

Answer 1

you need to change your json view hierachy a little:

public class MinimalView { };
public class AComplete extends MinimalView { };
public class BComplete extends MinimalView { };

then you can annotate your classes like

class A{
    @JsonView(MinimalView.class)
    String field1;
    @JsonView(AComplete.class)
    String field2;
    @JsonView(AComplete.class)
    Collection<B> bEntities;
 }

class B{
    @JsonView(Minimal.class)
    String field2;
    @JsonView(BComplete.class)
    String field3;
}

when you serialize using the view AComplete, the serializer will take the AComplete and MinimalView properties because AComplete extends MinimalView.
