ssh框架整合实例子-持久层

1.DAO接口 UserDAO

package com.yanek.demo.ssh.dao;

import java.util.List;

import com.yanek.demo.ssh.vo.User;

public interface UserDAO {

public void save(User user);
public List<User> findAll();

}

2.DAO接口实现 UserDAOImpl

package com.yanek.demo.ssh.dao;

import java.util.List;

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

import com.yanek.demo.ssh.vo.User;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {

public void save(User user) {

this.getHibernateTemplate().save(user);

}

public List<User> findAll()
{

try {
String queryString = "from User";
Query queryObject = getHibernateTemplate().getSessionFactory()
.openSession().createQuery(queryString);
return queryObject.list();
} catch (RuntimeException re) {
throw re;
}
}

}

3. vo: User

package com.yanek.demo.ssh.vo;

public class User implements java.io.Serializable {

private int id;

private String username;

private String password;

private String email;

public User() {

}
public User(int id, String username, String password, String email) {
super();
this.id = id;
this.username = username;
this.password = password;
this.email = email;
}
public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email;
}

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getPassword() {
return password;
}

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

public String getUsername() {
return username;
}

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

}

4. 配置文件： User.hbm.xm
