Answer 1

Change method to POST and send some data with HTTP POST so the (#RequestBody String body) binding works.
You could use SoapUi or HTTP Requester plugin for browsers to conveniently send HTTP POST.
Otherwise define method as:
#RequestMapping(method = RequestMethod.GET)
#ResponseBody
public String get() {
return "Some string";
}
