实体bean

package com.ljh.bean;

public class User implements java.io.Serializable{
private static final long serialVersionUID = -6904888263734117634L;
private Integer id;
private String username;
private String password;

public User() {}

public User(String username, String password) {
this.username = username;
this.password = password;
}

public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}

}

hibernate 映射 (user.hbm.xml 放在com.ljh.hbm包下)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
<class name="com.ljh.bean.User">
<id name="id">
<generator class="native"></generator>
</id>
<property name="username" length="15"/>
<property name="password" length="15"/>
</class>
</hibernate-mapping>

dao接口

package com.ljh.dao;

import com.ljh.bean.User;

public interface UserDao {
public void save(User user);
public User findUser(String username);
}

dao实现类

package com.ljh.dao.impl;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.ljh.bean.User;
import com.ljh.dao.UserDao;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao{
private static final String QUERY_BY_NAME = "select new User(username,password) from User where username=?";
@Override
public void save(User user) {
this.getHibernateTemplate().save(user);
}

@SuppressWarnings("unchecked")
@Override
public User findUser(String username) {
List list = this.getHibernateTemplate().find(QUERY_BY_NAME, username);
if(list==null||list.isEmpty()){
return null;
}
return (User)list.get(0) ;
}
}

serviceDao 接口
package com.ljh.service.dao;

import com.ljh.bean.User;

public interface UserServiceDao {
public void save(User user);
public boolean isExist(String username);
}

serviceDao 接口实现类

package com.ljh.service.dao.impl;

import com.ljh.bean.User;
import com.ljh.dao.UserDao;

public class UserServiceDaoImpl implements com.ljh.service.dao.UserServiceDao{
private UserDao userDao;
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}

@Override
public void save(User user) {
userDao.save(user);
}
@Override
public boolean isExist(String username) {
User user = userDao.findUser(username);
if(user==null){
return false;
}
return true;
}
}
