How to make POJO attribute optional for JSON response on certain condition ?

[SunilK Chauhan]

Hi,

I want to make POJO attribute optional for JSON response on certain condition.

Like below is my POJO for example.

public class A {

  public int a;
  public int b;

}

Here in response of this POJO class, we get both the attributes whether values are available or not.
But i want that on certain condition, Attribute 'b' should pass and on false condition it should not pass in response.

I think we can set conditional setter for it but don't know how to set it.

Can you please help me on this ?
