[실행화면]

1. 로그아웃 링크 연결

<td><a href="./DispatcherServlet?command=logout">로그아웃</a></td>

2. controller

1) src - controller.HandlerMapping.java에 logout 추가

else if(command.equals("logout")) c=new LogoutController();

2) src - controller.LogoutController.java

package controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; public class LogoutController implements Controller { @Override public String execute(HttpServletRequest request, HttpServletResponse response) throws Exception { HttpSession session = request.getSession(false); if(session!=null) session.invalidate(); return "redirect:index.jsp"; } }
