我在执行 CRUD 时遇到错误。在名为“dispatcher”的 DispatcherServlet 中未找到带有 URI [/Hotels] 的 HTTP 请求的映射 警告:不支持请求方法“POST”
This is the Room controller
@ Controller @RequestMapping(value = "/admin/room")
public class Roomcontroller {
@Autowired
private RoomService roomService;
@RequestMapping(method = RequestMethod.GET)
public String index(ModelMap map) throws SQLException {
map.addAttribute("Room", roomService.getAll());
return "admin/room/index";
}
@RequestMapping(value = "/addroom", method = RequestMethod.GET)
public String addRoom() throws SQLException {
return "admin/room/addroom";
}
@RequestMapping( value = "/editroom/{ro_id}", method = RequestMethod.GET)
public @ResponseBody ModelAndView edit(@PathVariable("ro_id") int ro_id) throws SQLException {
ModelAndView mv = new ModelAndView("admin/room/editroom");
mv.addObject("Room", roomService.getById(ro_id));
return mv;
}
@RequestMapping(value = "/deleteroom/{ro_id}", method = RequestMethod.GET)
public String delete(@PathVariable("ro_id") int ro_id) throws SQLException {
roomService.delete(ro_id);
return "redirect:/admin/room";
}
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@RequestParam("roomType") String roomType,
@RequestParam("roomDescription") String roomDescription, @RequestParam("roomNumber") int roomNumber
,@RequestParam("file") MultipartFile multipartFile,HttpServletRequest req) throws SQLException, IOException {
Room room = new Room();
room.setRoom_type(roomType);
room.setRoom_description(roomDescription);
room.setRoom_number(roomNumber);
// TO DO : Save room, fetch the id of saved room and set it through
// setter in above object.
if(room.getRo_id()==0){
File roomImageDirectory = new File("D:\\Hotels\\uploadedImages");
if (!roomImageDirectory.exists()) {
roomImageDirectory.mkdirs();
}
String[] fileNameToken = multipartFile.getOriginalFilename().split("\\.");
// You can change file name to be saved.
String newFileName = "room-" + room.getRoom_number() + "." + fileNameToken[fileNameToken.length - 1];
File roomImage = new File(roomImageDirectory, "/" + newFileName);
roomImage.createNewFile();
multipartFile.transferTo(roomImage);
room.setImage(newFileName);
roomService.insert(room);
}
else
{
roomService.update(room);
}
return "redirect:/admin/room";
}
}
最佳答案
您输入的JSP的form action不正确，您需要更改如下:
<form action="/admin/room/save" method="post" enctype="multipart/form-data">
