Hibernate测试程序---Hibernate操作数据库

此文主要强调的是Hibernate操作数据库的前期准备工作，也就是下面init()方法中的固定写法

package com.hibernate;

import static org.junit.Assert.*;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
/*
 * After代表在test()方法之后执行
 * Before代表在test()方法之前执行
 */
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

public class HibernateTest {
	private SessionFactory sessionFactory;
	private Session session;
	private Transaction transaction;
	
	@Before
	public void init() {
		/*
		 * 使用Hibernate框架的前期工作
		 * Hibernate4的固定写法
		 */
		Configuration configuration= new Configuration().configure();
		ServiceRegistry serviceRegistry=new ServiceRegistryBuilder().applySettings(configuration.getProperties())
	                                                                .buildServiceRegistry();
		sessionFactory=configuration.buildSessionFactory(serviceRegistry);
		session=sessionFactory.openSession();
		transaction=session.beginTransaction();
		
	}
	
	@After
	public void destroy() {
		transaction.commit();
		session.close();
		sessionFactory.close();
	}
	@Test
	public void test() {
		//此处为具体操作程序
	}

}

}
