我是靠谱客的博主冷静小猫咪，最近开发中收集的这篇文章主要介绍Web学习第一天：Servlet+JSP简单Demo，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

工具:MyEclipse2014+Tomcat7

1、建立Web工程

工程名为：RegisterSystem

2、在WebRoot目录下编写login.jsp

3、在src文件夹下创建com.ht.servlet包并编写Account.java

package com.ht.servlet;

public class Account {
//账户用户名与密码
private String username="";
private String password="";

public String getUsername(){
return this.username;
}

public void setUsername(String username){
this.username=username;
}

public void setPassword(String password){
this.password=password;
}
}

4、在com.ht.servlet包下编写CheckAccount.java

package com.ht.servlet;

import java.io.IOException;

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

public class CheckAccount extends HttpServlet{

/**
*
*/
private static final long serialVersionUID = 1L;

protected void doPos(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException{
doGet(request,response);
}

public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException{
HttpSession session = request.getSession();
Account acct = new Account();
String username = request.getParameter("username");
String password = request.getParameter("password");
acct.setUsername(username);
acct.setPassword(password);
if((username != null)&&(username.trim().equals("jsp"))){
if((password != null)&&(password.trim().equals("1"))){
System.out.println("Success");
session.setAttribute("account", acct);
String login_success = "success.jsp";
response.sendRedirect(login_success);
return;
}
}

String fail_login="fail.jsp";
response.sendRedirect(fail_login);
return;
}

}
