Getting 405 error from PostMan. Help!

[tangara goh]

Hi experts,

After battling for more than 5 hours and getting no way, I don't know who to ask so I am back here with more question.

@RequestMapping(value = "user", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
        public ResponseEntity<User> createUser(@RequestBody User user) {// can only be done by log in user
                System.out.println("POST ENDPOINT for creating User" + user);
                if (user == null) {
                        throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Invalid input");// 400
                }
                users.add(user); // users is from a List
                return new ResponseEntity<User>(user, HttpStatus.OK);
        }

So, I then test out this end point, just like other end points in Postman using Post.

As the postman image is really quite unreadable, so I am reproducing it in text as follows:

{ "Id" : 13,
   "username" : "orchid",
   "password" : "ismyname" 

and the error code is:

{ "timestamp" : timeanddate
  "status" : 405,
 "error" : "Method Not Allowed",
 "message" : "",
"path" "/user"
}

I hope someone can tell me what went wrong ? I have re-checked the path and re-read every line and comparing to the other controller end point that has the same create method but just can't find what is wrong....

I suspect it has to do with Spring internal wiring I don't know that for User it is particular sensitive.

Really, hope someone can point out what mistake cos I don't know how I will be viewed by my boss who already condemned me...this is supposedly a simple end point but it turns out exceedingly difficult for me...

Tks.
