测试类====

package com.Inf;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;

public class HibernateDemo {
@Test
public void demo1() {
System.out.println(“进入程序”);
//1.加载ibernate核心配置
Configuration configuration =new Configuration().configure();
//2。创建一个sessionfactory对象 相当于jdbc连接池
SessionFactory sessionFactory=configuration.buildSessionFactory();
//3.ͨ通过sessionfactory获取jdbc
Session session =sessionFactory.openSession();
//4.手动开启事务
Transaction transaction =session.beginTransaction();
//5.编写代码
Customer customer=new Customer();
customer.setCust_name(“国家”);
session.save(customer);
System.out.println(“保存结束”);
//6.事务提交
transaction.commit();
//7.关闭资源
session.close();
sessionFactory.close();
}
