Try this code:

@RequestMapping(method = RequestMethod.GET)
public @ResponseBody MyObj getJSON() {
    MyObj obj = new MyObj();

    return obj;

}

Put jackson in your classpath and @ResponseBody annotation in controller method handler.

Also enable mvc:annotation-driven in your servlet config.

In this case MyObj will be serialized in JSON format.
