package www.csdn.net.hiber2.dao;

import java.util.List;

public interface BaseDao<T,PK> {

	T findById(PK id);
	void deleteById(PK id)throws Exception;
	void delete(T entity)throws Exception;
	
	void deletes(String ids[])throws Exception;
	
	void update(T entity)throws Exception;
	void insert(T entity)throws Exception;
	
	List<T> findAll();
}

package www.csdn.net.hiber2.dao;

import www.csdn.net.hiber2.bean.User;

public interface UserDao extends BaseDao<User, Integer> {

}

六 ： 接口的实现类

package www.csdn.net.hiber2.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.Transaction;

import www.csdn.net.hiber2.bean.User;
import www.csdn.net.hiber2.dao.UserDao;
import www.csdn.net.hiber2.util.HibernateSessionFactory;

public class UserDaoImpl implements UserDao {

	@Override
	public User findById(Integer id) {
		
		return (User) HibernateSessionFactory.getSession().get(User.class, id);
		
	}

	@Override
	public void deleteById(Integer id) throws Exception {
		Session session=HibernateSessionFactory.getSession();
		Transaction ts=session.beginTransaction();
		session.delete(findById(id));
		ts.commit();
		session.close();
		
	}

	@Override
	public void delete(User entity) throws Exception {
		
		Session session=HibernateSessionFactory.getSession();
		Transaction ts=session.beginTransaction();
		session.delete(entity);
		ts.commit();
		session.close();
		
	}

	@Override
	public void deletes(String[] ids) throws Exception {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void update(User entity) throws Exception {

		Session session=HibernateSessionFactory.getSession();
		Transaction ts=session.beginTransaction();
		session.update(entity);
		ts.commit();
		session.close();
	}

	@Override
	public void insert(User entity) throws Exception {
		
		Session session=HibernateSessionFactory.getSession();
		Transaction ts=session.beginTransaction();
		session.save(entity);
		ts.commit();
		session.close();
		
	}

	@Override
	public List<User> findAll() {
		
		return HibernateSessionFactory.getSession().createQuery("from User").list();
	}

}

七：封装的解析xml 文件 获取链接对象等的操作 

package www.csdn.net.hiber2.util;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class HibernateSessionFactory {

	static Configuration cfg;
	static SessionFactory sessionFactory;
	static ServiceRegistry serviceRegistry;
	
	static{
		cfg=new Configuration().configure();// hibernate.cfg.xml
		//  创建服务注册对象 
		serviceRegistry =new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();
		
		// 创建sessionFactory 工厂对象
		sessionFactory=cfg.buildSessionFactory(serviceRegistry);
		
	}
	
	// 获取session 对象
	public static Session getSession(){
		return sessionFactory.openSession();
	}
}

八： 测试类

package www.csdn.net.hiber2.junit;

import java.util.List;

import org.junit.Test;

import www.csdn.net.hiber2.bean.User;
import www.csdn.net.hiber2.dao.UserDao;
import www.csdn.net.hiber2.dao.impl.UserDaoImpl;
import www.csdn.net.hiber2.util.HibernateSessionFactory;

public class UserTest {

	
	private UserDao userDao=new UserDaoImpl();
	
	@Test
	public void test(){
		
		System.out.println(HibernateSessionFactory.getSession());
	}
	@Test
	public void insert() throws Exception{
		
		User  entity=new User(null, "chong", "M", 19);
		
		userDao.insert(entity);
		
	}
	@Test
	public void findAll() throws Exception{
		
		
		List<User> entities=userDao.findAll();
		for (User user : entities) {
			System.out.println(user.toString());
		}
	}
	
}
