AJAX响应总是405

Question

I have an AJAX post

$.ajax({
        type: "POST",
        contentType: "application/json",
        url: "/rating/save",
        data: JSON.stringify(rating),
        dataType: "json",
        mimeType: "application/json",
        success: function (responseData) {
            console.log(responseData);
            window.location.href = "/welcome"
        },
        error: function (responseData) {
            console.log(responseData);
        }
    });

Controller

@Controller
public class RatingController {
........
    @RequestMapping(value = "/rating/save",method = RequestMethod.POST)
        public ResponseEntity<Object> saveRating(@RequestBody List<RatingDTO> ratingDTO) {
            return new ResponseEntity<>(ratingService.save(ratingDTO),HttpStatus.OK);
        }
}

Each time that I'm trying to process the response from the controller even if there is no exception I got

status: 405
statusText: "error"

The error says that the method is not allowed, but service from this endpoint works great.

You should set POST via method attribute:

$.ajax({
  method: "POST",
  ...
