logout.java

又一个课程设计 简易 JSP 论坛 功能较简单的那种, 界面上模仿了 Discuz JSP 本来就学的不行, 只是尽量实现了 MVC

package cn.ialvin.bbs.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import cn.ialvin.bbs.dao.DAOFactory;
import cn.ialvin.web.Servlet;

public class Logout extends Servlet {
	private static final long serialVersionUID = 1L;
	public Logout() { super(); }
	public void destroy() { super.destroy(); }
	public void doAction(
			HttpServletRequest request,
			HttpServletResponse response,
			PrintWriter out,
			DAOFactory factory)
			throws ServletException, IOException {
		HttpSession s = request.getSession(false);
		if (s != null) {
			s.removeAttribute("isLogin");
			s.removeAttribute("usr");
		}
		this.replace("../Index", out);
	}
