title: @RequestBody optional (e.g. required=false)
body: <p>Is there a way to make the @RequestBody annotation options (e.g. required=false) like RequestParam supports?</p>
  
  <p>My main path through the code is with a POST.  However, I'd like to also support a basic GET request via a browser basic http request for debugging purposes.  However when I try to do that I get a 415 unsupported media error.</p>
