Request method 'POST' not supported in Spring MVC

Question

Request method 'POST' not supported in Spring MVC

Please help me solve the problem

Jsp

    <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
        <%@ page contentType="text/html;charset=UTF-8" language="java" %>

    <html>
    <head>
         <title>Title</title>
    </head>

<body>

    <c:if test="${currentRoom.getLight()}">
        <form method="post" action="/room/allroom/">
            <input type="radio" name="status" value="turnOff">
            <button type="submit">Выключить</button>
        </form>
    </c:if>

    <c:if test="${!currentRoom.getLight()}">
        <form method="post" action="/room/allroom/">
            <input type="radio" name="status" value="turnOn">
            <button type="submit">Включить</button>
        </form>
    </c:if>
</body>

Controller

@Controller
@RequestMapping(path = "/room")
public class RoomController {
@GetMapping(path = "allroom/{roomNumber}")
    public ModelAndView getRoomById(@PathVariable("roomNumber") Integer roomNumber, ModelAndView modelAndView, HttpServletRequest httpServletRequest){
        modelAndView.setViewName("currentRoom");
        List<Room> roomList = roomService.allListRooms();
        Room room = roomList.get(roomNumber);
        httpServletRequest.getSession().setAttribute("currentRoom", room);
        return modelAndView;
    }

    @PostMapping(path = "allroom/{roomNumber}")
    public ModelAndView light(@PathVariable("roomNumber") Integer roomNumber, @RequestParam("status") String status, ModelAndView modelAndView, HttpServletRequest httpServletRequest){
        modelAndView.setViewName("currentRoom");
        if(status.equals("turnOn")){
            roomService.lightOn(roomNumber);
            return modelAndView;
        }
        if(status.equals("turnOff")){
            roomService.lightOff(roomNumber);
            return modelAndView;
        }
        return modelAndView;
    }

Mistake: Message Request method 'POST' not supported

Description The method received in the request-line is known by the origin server but not supported by the target resource.

You will submit by following the link action="/room/allroom/", although you have added two "/room/allroom/{roomNumber} "

Add a number to the link. So that the request is sent to"/room/allroom / 1 " say. Or remove {roomNumber} from the controller
