我为表单开发了两个方法，另一个用于修改预留。将显示一条消息和一条错误消息：＆＃34;必需的整数参数＆＃39; id＆＃39;不在场。请问你能帮帮我吗 我的控制器是：
@Controller
@RequestMapping("/reservations")
public class ReservationController {
@Autowired
ReservationService reservationService;
@Autowired
private UserService userService;
@Autowired
ClassroomService classroomService;
@RequestMapping(value = "/updatereservationForm", method = RequestMethod.GET)
public ModelAndView UdateReservationSalle(@RequestParam(value="id",
required = true) Integer id, ModelMap model) {
Reservation reservation = reservationService.findById(id) ;
model.addAttribute("reservation", reservation);
List <Classroom> classrooms = classroomService.getAll();
model.addAttribute("classrooms", classrooms);
List <User> users = userService.getAll();
model.addAttribute("users", users);
return new ModelAndView("reservation/updateResR", model);
}
@RequestMapping("/updateReservation")
public ModelAndView updateResR(@RequestParam("id") Integer id,ModelMap
model) {
Reservation reservation=reservationService.findById(id);
model.addAttribute("reservation",reservation);
return new ModelAndView("updateResR",model);
}
@RequestMapping("/updateReservationRInput")
public ModelAndView updateReservationRInput
(@RequestParam("id") Integer id,
@RequestParam(name="roomid",defaultValue="-1") Integer roomid,
@RequestParam("datebegin") @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
Date datebegin,@RequestParam("dateend")
@DateTimeFormat(pattern =
"yyyy-MM-dd HH:mm") Date dateend,
Integer userid,RedirectAttributes redirectAttributes, ModelMap model)
Reservation reservation = reservationService.findById(id);
Classroom classroom = classroomService.findById(roomid);
User user = userService.findById(userid);
reservation.setClassroom(classroom);
reservation.setUser(user);
reservation.setDateBegin(datebegin);
reservation.setDateEnd(dateend);
return testReservation(roomid, datebegin, dateend,
redirectAttributes,reservation);
}
