Question

I’ve worked with struts for quite sometime now, but never figured the awesome “json” response type.

I have a large list of objects that I want to return to client. I use only a subset of these fields (typically ‘displayName’s) on the UI.

Is there a way to restrict the fields that are serialized as JSON back to the client?

One obvious approach I could think of is to create a view object which has subset of the fields. Please suggest the best practice here.

Answer 1

You can use exclude property of json plugin to exclude properties which you don’t want to serialize.

<interceptor-ref name="json">
  <param name="enableSMD">true</param>
  <param name="excludeProperties">
    login.password,
    studentList.*\.sin
  </param>
</interceptor-ref>
