一个简单的用户注册、登录和利用邮箱找回密码的S2SH程序

1、在model（po,vo等）层建立一个用户（User.java）信息

　　a)用户信息

View Code

 1 package com.ibm.forgotpassword.model;
 2 
 3 public class User {
 4 
 5     private int id;
 6     private String email;
 7     private String username;
 8     private String password;
 9 
10     public int getId() {
11         return id;
12     }
13     public void setId(int id) {
14         this.id = id;
15     }
16     public String getEmail() {
17         return email;
18     }
19     public void setEmail(String email) {
20         this.email = email;
21     }
22     public String getUsername() {
23         return username;
24     }
25     public void setUsername(String username) {
26         this.username = username;
27     }
28     public String getPassword() {
29         return password;
30     }
31     public void setPassword(String password) {
32         this.password = password;
33     }
34     
35 }

　　b)建立对应的User.hbm.xml

21 </hibernate-mapping>

2 DAO层（IUserDAO接口和UserDAO实现类）

　　a)IUserDAO接口

View Code

 1 package com.ibm.forgotpassword.dao;
 2 
 3 import com.ibm.forgotpassword.model.User;

 9      * @param user
10      * @return
11      */
12     public boolean save(User user);
13     
14     /**
15      * 根据邮箱查找用户信息
16      * @param email
17      * @return
18      */
19     public User findUserByEmail(String email);
20     
21     /**
22      * 根据邮箱和密码查找用户信息
23      * @param email
24      * @param password
25      * @return
26      */
27     public User findUserByEmailAndPssword(String email,String password);
28 
29 }

　　b)UserDAO实现类

View Code

 1 package com.ibm.forgotpassword.dao.impl;
 2 
 3 import org.hibernate.HibernateException;
 4 import org.hibernate.Query;
 5 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

10 public class UserDAO extends HibernateDaoSupport implements IUserDAO {
11 
12     @Override
13     public User findUserByEmail(String email) {
14         try{
15             String hql = "from User u where u.email = ?";
16             Query query = this.getSession().createQuery(hql);
17             query.setString(0, email);
18             User user = (User) query.uniqueResult();
19             return user;
20         }catch(HibernateException e){
21             e.printStackTrace();

32             e.printStackTrace();
33             return false;
34         }
35     }
