How to return json data selectively in a struts2 action class

Question

I have several properties with getter and setter method in one action class.

Those properties do not perform the same task. Actually, they respond to different busin

Answer 1

Struts2-JSON plugin allows you to exclude null properties

<result type="json">
  <param name="excludeNullProperties">true</param>
</result>

or exclude certain parameters from being serialized

<result type="json">
  <param name="excludeProperties">
    login.password,
    studentList.*\.sin
  </param>
</result>
