I typically retrieve POST parameters like the following:

@RequestMapping(method = RequestMethod.POST)
public ModelAndView create(
    @RequestParam(value = "first_name", required = false) String firstName,
    HttpServletRequest request
) {

But what if some parameters are in the URL like http://example.com/post/path?last_name=Smith? Is Spring supposed to grab all the parameters from both the URL and the POST data when RequestMapping is POST?

Basically, Facebook sends a signed_request parameter via POST and other parameters like request_ids at the same time via URL parameters. I need to get both.

    Yes, spring will get all parameter values (in form and url) for a POST request. but in your case 

     @RequestParam(value = "first_name", required = false) String firstName,

    will be null. Because in your url, the parameter name is last_name. 😀
