解决Ajax发送DELETE请求时后台无法接收到参数的问题（Restful风格）

$.ajax({
  url: '/cyberspace/vrv/event/delete/1002?startTime="2018-03-07 11:39:27"&userId=123456',
   type: "delete",
   contentType: "application/json",
   dataType: "json",
   success: function (msg) {
       console.log(msg);
   }
});

@DeleteMapping("/vrv/event/delete/{eventId}")

$.ajax({
            url: '/cyberspace/vrv/event/delete/1002',
            type: 'POST',
            data: {
                startTime: "2018-03-07 11:39:27",
                userId: 123456,
                _method: 'DELETE'
            },
            success: function (msg) {
                console.log(msg);
            }
        });

@RequestMapping(value = "/vrv/event/delete/{eventId}", method = RequestMethod.DELETE)

  @ApiOperation("删除管理员信息")
    @DeleteMapping("/delManagerUserById/{managerIdStr}")
    @ResponseBody
    public String delManagerUserById(@PathVariable("managerIdStr") String managerIdStr){

        System.out.println("要删除的ID："+managerIdStr);
        if (managerIdStr==null || managerIdStr=="")
            return ResultUtils.ResultFail("参数不能为空");

        int s = managerUserService.delManagerUserById(managerIdStr);

        if(s<0)
            return ResultUtils.ResultFail("删除失败了");


        return new ResultUtils().ResultSuccess(null).toString();
    }
