Edit Data

[Arian Zand]

Hey,

As some already know I creating Crud app
I already have Read,Delete and create but I get an error while updating data

When I click on a reservation(for a hotel) I get the values from my reservation, in my form i can edit the value and I like to update it to the DB

My controller for my edit

@RequestMapping(value={"/reservationEdit"},method=RequestMethod.GET)
    public String reservationEdit(@RequestParam("reservationId") Integer id, ModelMap model){
		//reservationdao.getById(id);
        model.addAttribute("dereservatieUpdate",reservationdao.getById(id));
        return "/reservationEdit";
    }
	
	@RequestMapping(value={"/reservationEdit"},method=RequestMethod.POST)
    public String reservationEditUpdate(@ModelAttribute("dereservatieUpdate") @RequestParam("reservationId") Integer id, @Valid Reservation reservation,
                                                        BindingResult result, ModelMap model){
		
	  //if (result.hasErrors()) return "/reservationEdit";
      reservationdao.updateReservation(id);
       
      return "/reservations";
    }

In my Dao I only have one parameter the reservation ID (Is this right?)

public Reservation updateReservation(int reservationID);

In my DaoImpl I update my data
, I dont know which function to use to update data , I used refresh... / Also tried Merge

public Reservation updateReservation(int reservationID) {
		Reservation reservation = getById(reservationID);
		
		em.refresh(reservation);
		return reservation;
	}

If i click on update i get this error:
SEVERE: Servlet.service() for servlet appServlet threw exception
java.lang.IllegalStateException: Handler parameter annotations are exclusive choices - do not specify more than one such annotation on the same parameter: public java.lang.String eu.test.test4.controller.ReservationController.reservationEditUpdate(java.lang.Integer,eu.test.test4.model.Reservation,org.springframework.validation.BindingResult,org.springframework.ui.ModelMap)


EDIT

I dont know why but I have "0" as reservationId in my Post Method controller
Is there something wrong with my modelattribute ?

What version of Spring are you using? If you are using 3.1 the fix is a bit more flexible. See below link.
