JavaWeb用户信息管理系统-用户退出登录

1 退出页面修改

 <li><cite></cite><a href="logout.do" target="rightFrame">退出登录</a><i></i></li>

跳转至logout.do

2 退出登录的servlet

/**
 * 用户退出登录
 */
@WebServlet("/logout.do")
public class LogoutServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        this.doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        HttpSession session = req.getSession();
        session.invalidate();
        resp.sendRedirect("login.jsp");
    }
}

因为写了监听器，获得session销毁即可，不必要再去remove去session，直接销毁就可以了，然后调用监听器进行删除。
