Ajax中Delete请求参数 后台无法获取的解决方法（Restful风格）

方法一：

在ajax中写入data来传参时，直接把参数拼接到url后面

例如：

 $.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}")

方法二：

$.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)
