AJAX響應總是405

Question

我有一個AJAX帖子

$.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);
        }
    });

調節器

@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);
        }
}

每次我試圖處理來自控制器的響應，即使我沒有例外

status: 405
statusText: "error"

該錯誤表明該方法不允許，但來自此端點的服務運行良好。

您應該通過method屬性設置POST：

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