Use Gson to serialize a POJO

Question

I use GSON serialize POJO -- both the object before and after altered.

The altered one (call it A) which is setup by Struts2 could easily serialized to Json.

Brandon was right. Here is another solution if you don't want to use any annotation or modify your POJO class. This may help for any other guys.

Type typeOfSrc = new TypeToken() {}.getType(); //this helps for generic one.
gson.toJson(obj, typeOfSrc); or gson.toJson(obj, A.class);
