Restful) Spring form tag를 이용하여 PUT,DELETE 사용하기

SPRING MVC 

 

class UserController

 

	@RequestMapping("{uid}/form")
	public String updateForm(@PathVariable("uid") String userId, Model model, HttpSession session){
				
		if(userId ==null){
			throw new IllegalArgumentException("사용자 아이디가 필요합니다.");
		}
		
		User temp =(User)session.getAttribute("user");
		if(temp==null){
			throw new NullPointerException();
		}
		
		User user1=new User();
		user1.setUserId(userId);
		if(!user1.matchUserId(temp.getUserId())){
			throw new NullPointerException();
		}
		
		User user =userDao.findById(userId);
		model.addAttribute("user", user);
		return "users/form";
	}
	
	
	@RequestMapping(value="", method=RequestMethod.PUT)
	public String update(@Valid User user, Model model, BindingResult bindingResult , HttpSession session){
		logger.debug("User : {} " , user);
		if(bindingResult.hasErrors()){
			logger.debug("Binding Result has error!");
			List<ObjectError> errors=bindingResult.getAllErrors();
			for(ObjectError error : errors){
				logger.debug("error : {}, {}", error.getCode(), error.getDefaultMessage());
			}
			model.addAttribute("user", user);
			return "users/form";
		}
		
		User temp =(User)session.getAttribute("user");
		if(temp==null){
			throw new NullPointerException();
		}
		
		if(!user.matchUserId(temp.getUserId())){
			throw new NullPointerException();
		}
		
		
		userDao.update(user);
		logger.debug("Database : {} " , userDao.findById(user.getUserId()));
