java - 已经在web.xml中配置过滤器,为何无法提交put请求?

web.xml中配置过滤器

    
        HiddenHttpMethodFilter
        org.springframework.web.filter.HiddenHttpMethodFilter
    
    
        HiddenHttpMethodFilter
        /*
    

jsp中使用put提交ajax请求

        //提交到后台的RESTful
        $.ajax({
           type: "PUT",
           url: "/rest/item",
           data: $("#itemeEditForm").serialize(),
           statusCode:{
               204:function(){
                   $.messager.alert('提示','修改商品成功!','info',function(){
                        $("#itemEditWindow").window('close');
                        $("#itemList").datagrid("reload");
                    });
               },
               500:function(){
                   $.messager.alert('提示','修改商品失败!');
               }
           }
    
        });

后端controller接受请求

@RequestMapping(method = RequestMethod.PUT)
    public ResponseEntity updateItem(Item item, @RequestParam("desc") String desc){
        try {
        
            this.itemService.updateItem(item,desc);
            //200
            return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
        } catch (Exception e) {
            e.printStackTrace();
            logger.error("修改商品出错");
        }
        //500
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }
    

控制台输出错误
