Parse using Jackson JSON

eg:

{
"foo" : ["1","2","3","4"],
"bar" : "xxxx",
"baz" : "yyyy"
}

Could be mapped to this class:

public class Fizzle{
    private List<String> foo;
    private boolean bar;
    private int baz;
    // getters and setters omitted
}

Now if you have a Controller method like this:

@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
    return new Fozzle(input);
}

You can use com.google.gson for it:

@RequestMapping(value = "/request", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody ResponseClass addDeparturePoint(@RequestBody String request) {
    Gson gson = new Gson();
    RequestClass request = gson.fromJson(request, RequestClass.class);
    ResponseClass response = buildResponce(request);
    return response;

}
