What is the easiest way to convert / display a JSON string in javabean?

Question

I have a JSON string that I read and would like to parse / map it to a JavaBean so that I can use it in my Java code. What is the easiest way / library for?

Answer 1

XStream is renowned for ease of use and supports JSON:

Answer 2

I wrote a JSON library to do just that.

http://code.google.com/p/svenson/

With svenson you would do something like:

// assume json to be a JSON dataset as String MyBean bean = JSONParser.defaultJSONParser().parse(MyBean.class, json); 

Svenson gives you the freedom to use either maps / lists or your own POJOs to convert data to and from JSON.

Answer 3

How about jackson ? As mentioned above, the mapping is pretty simple:

MyBean bean = new ObjectMapper (). readValue (json, MyBean.class);

handles maps, lists, primitives, beans; with proper generic support and a complete configuration of the mapping process.
