mypageServlet.java (mypage.do)

로그인이 완료된다면, mypage.do 페이지로 이동할 수 있도록 header.jsp 에서 설정해놨다.

로그인이 완료되어있는 상태인지 확인하기 위해서 session 정보를 이용하여 doGet 메소드에서 확인하자.

public class MypageServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		//session 정보가 있는지 확인하기
		HttpSession session = request.getSession();
		EmployeesVO emp = (EmployeesVO)session.getAttribute("loginUser");
		if(emp!=null) {
			RequestDispatcher dispatcher = request.getRequestDispatcher("mypage.jsp");
			dispatcher.forward(request, response);
		}
	}

	
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		EmployeesDAO eDao = EmployeesDAO.getInstance();
		eDao.updateMember(member);

		//수정완료
		
		HttpSession session = request.getSession();
		
		 //방금 updqte한 member를 session에 담아두기.
		request.setAttribute("member", member);

		EmployeesVO emp = eDao.getMember(member.getId());
		session.setAttribute("loginUser",emp);//session에 저장하기 
		
		int result = eDao.userCheck(member.getId(), member.getPass(), member.getLev());
		session.setAttribute("result", result);
		RequestDispatcher rd = request.getRequestDispatcher("joinsuccess.jsp");
		rd.forward(request, response);
	}

}

joinsuccess.jsp

mypageservlet.java 에 session에서 emp와 result

request 에서 message -> ${message}

request 에서 member -> ${member.id}

lev는 lev속성${member.lev}으로해도 되고 result<c:choose> </c:choose> 로 해도된다.
