How to efficiently map a org.json.JSONObject to a POJO?

Question

This question must have been asked before, but I couldn\'t find it.

I\'m using a 3rd party library to retrieve data in JSON format. The library offers the data to me

If you're not tied with Jackson, you can use the handy google-gson library as an alternative. It requires only one jar and is very simple to use:

Converting a java object into a JSON string:

  String json_string = new Gson().toJson(an_object);

Creating a java object from a JSON string:

  MyObject obj = new Gson().fromJson(a_json_string, MyObject.class);

I dont't know about performance compared to Jackson, but it's hard to be simpler than this... Gson is a stable and widely used library.
