</id>
<property name="name" >
<column name="name"></column>
</property>
<property name="password" column="password"></property>
</class>
</hibernate-mapping>
4.相关类与接口的代码实现：
（1）控制组件 LoginAction.java
package com.ssh.action;
import com.ssh.entity.User;
import com.ssh.service.InterfaceUserService;
/**
* 登录测试
* @author Administrator
*
*/
public class LoginAction {
//用于封装用户请求的参数
private User user;
//处理业务逻辑的组件
private InterfaceUserService userService;
/*
* user 属性相应的setter、getter方法
*/
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
//依赖注入所需要的setter 方法
public void setUserService(InterfaceUserService userService) {
this.userService = userService;
}
/**
* 判断是否可以成功登录
* @return
*/
public String canLogin(){
String result = "fail";
if(userService.canLogin(user)){
result="success";
}
return result;
}
}
（2）接口 InterfaceUserDAO.java
package com.ssh.action;
import com.ssh.entity.User;
import com.ssh.service.InterfaceUserService;
/**
* 登录测试
* @author Administrator
*
*/
public class LoginAction {
//用于封装用户请求的参数
private User user;
//处理业务逻辑的组件
private InterfaceUserService userService;
/*
* user 属性相应的setter、getter方法
*/
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
//依赖注入所需要的setter 方法
public void setUserService(InterfaceUserService userService) {
this.userService = userService;
}
/**
* 判断是否可以成功登录
* @return
*/
public String canLogin(){
String result = "fail";
if(userService.canLogin(user)){
result="success";
}
return result;
}
}
（3）实现类 UserDaoImpl.java
package com.ssh.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.ssh.dao.InterfaceUserDAO;
import com.ssh.entity.User;
/**
* 必须继承HibernateDaoSupport
* @author Administrator
*
*/
public class UserDaoImpl extends HibernateDaoSupport implements InterfaceUserDAO{
/**
* 根据用户名和密码判断是否登录成功
*/
@Override
public boolean canLogin(User user) {
boolean flag = false;
//通过用户名获取数据库的对应记录，若相同则可登录
if(user==null && user.getName()==null){
return false;
}
// System.out.println(user);
List<User> list = getHibernateTemplate()
.find("from User where name=?", user.getName());
if(list.size()!=1){
return false;
}
User real =list .get(0);
// System.out.println(real);
if(user.equals(real)){
flag=true;
}
return flag;
}
}
（4）实体类User
package com.ssh.entity;
/**
* 与数据库user表对应的尸体类
* @author Administrator
*
*/
public class User {
private int id;
private String name;
private String password;
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((name == null) ? 0 : name.hashCode());
result = prime * result
+ ((password == null) ? 0 : password.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
User other = (User) obj;
if (name == null) {
if (other.name != null)
return false;
} else if (!name.equals(other.name))
return false;
if (password == null) {
if (other.password != null)
return false;
} else if (!password.equals(other.password))
return false;
return true;
}
@Override
public String toString() {
return "User [id=" + id + ", name=" + name + ", password="
+ password + "]";
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
（5）接口InterfaceUserService.java
package com.ssh.service;
import com.ssh.entity.User;
public interface InterfaceUserService {
//判断是否登录成功
public boolean canLogin(User user);
}
（6）实现类 UserServiceBean.java
package com.ssh.service.impl;
import com.ssh.dao.InterfaceUserDAO;
import com.ssh.entity.User;
import com.ssh.service.InterfaceUserService;
public class UserServiceBean implements InterfaceUserService {
//定义成员变量UserDao并创建相应的setter方法用于依赖注入
private InterfaceUserDAO userDao;
public void setUserDao(InterfaceUserDAO userDao) {
this.userDao = userDao;
}
/**
* 判断是否可以成功登录
*/
@Override
public boolean canLogin(User user) {
return userDao.canLogin(user);
}
}
