@RequestMapping(value="/save",method=RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE,produces=MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public int save(@RequestBody Reservation reservation) {
        System.out.println(reservation.getTime());
        return reservationRepo.save(reservation);   
    }

我有一个angular post请求，它发送JSON数据和一个处理该请求的spring控制器。当我尝试这个我得到了错误客户端发送的请求在语法上是不正确的。前端的数据来自一个表单。我使用引导日期选择器进行日期选择。谁能指出我的错误

无需对数据对象进行字符串化。

            $http({
                  method: 'POST',
                  url: '/Eatery/save',
                  contentType:'application/json',
                  dataType:'json',
                  data:resvnCtrl.user
            });
