Subject JSON plugin: filter fields in a Map with Lists
Date Tue, 24 Sep 2019 09:59:50 GMT

In MyAction, I have the following instance variable:

     Map<String, List<MyObject>> result;

And MyObject has the following properties:

     |- interestingProperty
     |- notInterestingProperty

I want to return the action result as a JSON. So, in my struts 
configuration I have:

     <action name="MyAction" method="execute" class="myAction">
         <result name="success" type="json">
             <param name="includeProperties">

This returns all keys/values in result map. But I want to write a JSON 
with only interestingProperty of each MyObject (which are in a list).

I've fiddled with the regular expression for a while, but could not find 
a way to do it.

Is it possible to achieve what I need?
