[MVC 실습] 로그인하고 게시판 운영하기_3

 

③ 로그아웃은 간단한게 쓰던 세션을 불러와서 무효화 해주면 된다. 

 

● HttpSession session = request.getSession(false); //새 세션 말고 쓰던거 가져와라
● session.invalidate(); //세션 무효화 

package member.controller;

import java.io.IOException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

/**
 * Servlet implementation class logout
 */
@WebServlet("/member/logout")
public class logout extends HttpServlet {
	private static final long serialVersionUID = 1L;

	/**
	 * @see HttpServlet#HttpServlet()
	 */
	public logout() {
		super();
		// TODO Auto-generated constructor stub
	}

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		HttpSession session = request.getSession(false); //새 세션 말고 쓰던거 가져와라
		session.invalidate(); //세션 무효화 
		RequestDispatcher dis = request.getRequestDispatcher("/index.jsp");
		dis.forward(request,response);
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}

 

 

 

④ 로그인 후 내 정보 보러 가기 

<button><a href = "${pageContext.request.contextPath }/member/myinfo?id=${sessionScope.loginId }"> 내 정보 확인 </a></button><br/>

 

위의 버튼을 누르게 되면 하기와 같은 페이지로 이동하게 된다.  

 

아래 주소창에서 보이는 것 처럼 {pageContext.request.contextPath }/member/myinfo?id=${sessionScope.loginId } = webApp3/member/myinfo?id=admin_id 이다 

 

 

▶ Servlet 페이지 구현 

package member.controller;

import java.io.IOException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import member.MemberService;
import member.memberVo;

/**
 * Servlet implementation class MyInfo
 */
@WebServlet("/member/myinfo")
public class MyInfo extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public MyInfo() {
        super();
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		request.setCharacterEncoding("euc-kr");
		response.setCharacterEncoding("euc-kr");
		response.setContentType("text/html; charset = EUC-KR");
		
		String id = request.getParameter("id"); 
		
		MemberService service = new MemberService();
		memberVo m = service.getMember(id);	
		
		request.setAttribute("m", m); 
		
		RequestDispatcher dis = request.getRequestDispatcher("/member/myinfo.jsp");
		dis.forward(request, response);	
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		request.setCharacterEncoding("euc-kr");
		response.setCharacterEncoding("euc-kr");
		response.setContentType("text/html; charset = EUC-KR");
				
		String id = request.getParameter("id"); 
		String pwd = request.getParameter("pwd");
		String name = request.getParameter("name");
		
		MemberService service = new MemberService(); 
		
		service.Editmyinfo(new memberVo(id,pwd,name,null));
		
		response.sendRedirect(request.getContextPath() + "/member/myinfo?id=" +id); 
		
	}
}

 

 

▶ JSP 페이지 구현 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>

<style type="text/css">
 a:link { color: black; text-decoration: none;}
 a:visited { color: black; text-decoration: none;}
 a:hover { color: black; text-decoration: underline;}
</style>

</head>

<body>
<form  action = "${pageContext.request.contextPath }/member/myinfo" method ="post" >
<h3> ${m.id }님의 정보</h3>

<table border = "1">

<tr><th>ID</th><td><input type = "text" name = "id" value = "${m.id }" readonly></td></tr>
<tr><th>PWD</th><td><input type = "password" name = "pwd" value = "${m.pwd }"></td></tr>
<tr><th>NAME</th><td><input type = "text" name = "name" value = "${m.name }"></td></tr>
<tr><th>EMAIL</th><td><input type = "text" name = "email" value = "${m.email }" readonly></td></tr>
<tr><th>수정</th>
<td><input type = "submit" value = "수정"> </td></tr> 
<tr><th>탈퇴</th>
<td><button><a href = "${pageContext.request.contextPath }/member/out?id=${m.id }"> 탈퇴</a></button></td> 
<tr><th>기타</th>
<td><button><a href = "${pageContext.request.contextPath }/member/result.jsp" >메인으로 돌아가기 </a></button></td> </tr>
</table>
</form>



</body>
</html>
