href="login" 이니까 HomeController의 login을 찾는다!

3.loginform.jsp 작성

대충 테이블 만들어서

    <form action="login" method="post">
    <input type="submit">

이렇게 해서 만들어주고 다시 2번의 Controller로 가서 로그인 완성하기

위의 Controller의 로그인 부분만 따서 보면

top.jsp에서 로그인 화면으로 이동
	@RequestMapping(value = "/logingo")
	public String logina() {
		return "loginform";
	}

로그인 폼에서 입력받은 데이터를 HomeController의 login으로 전송
if 문에서 로그인 정보가 있는지 없는지 member429(dto)에서 확인

	@RequestMapping(method = RequestMethod.POST, value = "/login")
	public String login(HttpServletRequest request, Model mo, RedirectAttributes ra) {
		String id = request.getParameter("id");
		String pw = request.getParameter("pw");
		Service dao = sqlSession.getMapper(Service.class);
		Member429VO dto = dao.login(id, pw);
		HttpSession hs = request.getSession();
		if (dto != null) {
			hs.setAttribute("member", dto);
			hs.setAttribute("loginstate", true);
			return "redirect:index";
		} else {
			ra.addAttribute("loginresult", "loginfail");
			return "redirect:memberinputa";
		}
	}

로그아웃

	@RequestMapping(value = "/logout")
	public String logout(HttpServletRequest request) {
		HttpSession hs = request.getSession();
		hs.removeAttribute("member");
		hs.removeAttribute("loginstate");
		hs.setAttribute("loginstate", "loginfail");
		return "redirect:index";
	}

4.로그인을 만들었으니까 로그인 상태에 따른 접근 관리 해주기

3번에서 설정한 loginstate를 여기저기 써먹으면 됨
loginstate=false 면 로그인이 안됐다는 뜻으로 main으로 돌아감

@RequestMapping(value = "/")
	public String home(HttpServletRequest request) {
		HttpSession hs = request.getSession();
		hs.setAttribute("loginstate", false);
		return "main";
	}

loginstate true=로그인 O
loginstate false=로그인 X
참일때 전달받은 정보를 list로 저장하여 memberout으로 보냄
거짓일때는 다시 main으로

@RequestMapping(value = "/memberout")
	public String memberout(HttpServletRequest requestm, Model mo, RedirectAttributes ra) {
		HttpSession hs = requestm.getSession();
		if ((boolean) hs.getAttribute("loginstate")) {
			Service dao = sqlSession.getMapper(Service.class);
			ArrayList<Member429VO> list = dao.memberout();
			mo.addAttribute("list", list);
			return "memberout";
		} else {
			ra.addAttribute("result", "loginfail");
			return "redirect:index";
		}
	}

loginstate의 true/false값에 따라 ...

@RequestMapping(value = "/infoout")
	public String inout(HttpServletRequest request, Model mo, RedirectAttributes ra) {
		Service dao = sqlSession.getMapper(Service.class);
		ArrayList<Info429VO> list = dao.infoout();
		HttpSession hs = request.getSession();
		if ((boolean) hs.getAttribute("loginstate")) {
			mo.addAttribute("list", list);
			return "infoout";
		} else {
			ra.addAttribute("result", "loginfail");
			return "redirect:index";
		}
	}

loginstate의 true/false값에 따라 ...2

@RequestMapping(value = "/scoreouta")
	public ModelAndView scoouta(HttpServletRequest request, RedirectAttributes ra) {
		Service dao = sqlSession.getMapper(Service.class);
		ArrayList<Score429VO> list = dao.scoreout();
		ModelAndView mav = new ModelAndView();
		HttpSession hs = request.getSession();
		if ((boolean) hs.getAttribute("loginstate")) {
			mav.addObject("list", list);
			mav.setViewName("scoreout");
			return mav;
		} else {
			ra.addAttribute("result", "loginfail");
			mav.setViewName("redirect:index");
			return mav;
		}
	}

암튼 이러케 해서 login을 만들어줌

처음에는 top.jsp에 loginstate를 만들었는데 이 방법이 하나하나 처리할때는 좋은거 같기도 하고 아닌거 같기도하고 뭐 그렇다
⭐내가 만든 코드의 각 이름들을 잘 구분하는게 중요한 듯 헤매지 않도록 정신차리삼⭐
