一个jsp的oa系统,里面有很多亮点学习!

package com.oa.lp.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;

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

import com.oa.lp.dao.EmployeeDAO;
import com.oa.lp.database.DataBase;
import com.oa.lp.model.Employee;

public class LogoutServlet  extends TopServlet {

	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		//安全退出
		HttpSession session = request.getSession();
		session.removeAttribute("emp");
		session.removeAttribute("powers");
		session.removeAttribute("menus");
		session.invalidate();
		this.sendRedirect(request, response,"/login.jsp");
		
	}
