servlet的登陆案例

Users.java

 1 package com.po;
 2 
 3 public class Users {
 4     private String username;
 5     private String password;
 6     
 7     public Users(){};
 8     
 9     public String getUsername() {
10         return username;
11     }
12     public void setUsername(String username) {
13         this.username = username;
14     }
15     public String getPassword() {
16         return password;
17     }
18     public void setPassword(String password) {
19         this.password = password;
20     }
21     
22     
23 }

新建GoLogin.java和LoginServlet.java的servlet类

分别修改他们的doGet和doPost方法

1  <form action="servlet/LoginServlet" method="post">
2         <table>
3             <tr><td>用户名:</td><td><input type="text" name="username" /></td></tr>
4             <tr><td>密码:</td><td><input type="password" name="password" /></td></tr>
5             <tr><td></td><td><input type="submit" value="登陆" /></td></tr>
6         </table>
7     </form>

loginFailed.jsp

1  <h1>登陆失败</h1>
2 <a href="servlet/GoLogin" >返回登陆界面</a>
