Question

I have a controller with two methods. One to delete a user another to remove a user from a role.

    @Controller
    @RequestMapping(value="/rest/users/**")
    public class UsersCtrlr {

        @RequestMapping(value="/{username:.+}", method=RequestMethod.DELETE)
        public @ResponseBody HttpStatusDoc deleteUser(HttpServletRequest req, @PathVariable String username) {
         ...
        }

        @RequestMapping(value="/{username:.+}/roles/{role:.+}", method=RequestMethod.DELETE)
        public @ResponseBody HttpStatusDoc deleteUserRole(HttpServletRequest req, @PathVariable String username, @PathVariable String role) {
         ...
        }
    }

My front end makes a jquery ajax call with a url as follows:

/rest/users/[e-mail]/roles/some_role

This uri is being mapped to the deleteUser method with a username equal to some_role

I’m trying to get the uri to map to the deleteUserRole and have the username set to [e-mail] and role set to some_role.

Why won’t the uri map to the deleteUserRole?
Does it have something to do with the regular expressions in the RequestMappings?

Answer 1

It is likely because of ** in your class @RequestMapping annotation , your mapping for deleteUser will be /rest/users/**/{username:.+} and for deleteUserRole will be /rest/users/**/{username:.+}/roles/{role:.+} and the first one will match up to /rest/users/[e-mail]/roles/some_role pattern. It should work if ** is removed from the class @RequestMapping annotation
