import java.util.Date;

//import javax.transaction.Transaction;

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;


import org.junit.After;

import org.junit.Before;

import org.junit.Test;




//测试类


public class StudentsTest {


private SessionFactory sessionFactory;

private Session session;

private Transaction transaction;

@Before

public void init(){

//创建配置对象

Configuration config = new Configuration().configure();

  //创建服务注册对象

//serviceRegistry serviceRegistry =new ServiceRegistryBuilder().applySettings(config.getProperty());

//这里有错误，转换不了，用了强制转换

ServiceRegistry serviceRegistry =new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();

  //创建会话工厂对象

sessionFactory =config.buildSessionFactory(serviceRegistry);

//会话对象

session = sessionFactory.openSession();

//开启事务

      transaction = session.beginTransaction();

}

@After

public void destory(){

transaction.commit();//提交事务

session.close();     //关闭会话

sessionFactory.close();//关闭会话工厂

}

@Test

public void testSaveStudents(){

   //生成学生对象

Students s = new Students(1,"张三丰","男",new Date(),"武当山");

session.save(s);//保存对象进入数据库

}

}
