1 导入所需的jar包
1 导入hibernate必须的jar包
2 导入驱动包
2 创建数据库,准备表,实体
1 创建hibernate数据库
CREATE DATABASE hibernate;
2 创建cst_customer表
CREATE TABLE `cst_customer` (
`cust_id` BIGINT(32) NOT NULL AUTO_INCREMENT COMMENT '客户编号(主键)',
`cust_name` VARCHAR(32) NOT NULL COMMENT '客户名称(公司名称)',
`cust_source` VARCHAR(32) DEFAULT NULL COMMENT '客户信息来源',
`cust_industry` VARCHAR(32) DEFAULT NULL COMMENT '客户所属行业',
`cust_level` VARCHAR(32) DEFAULT NULL COMMENT '客户级别',
`cust_linkman` VARCHAR(64) DEFAULT NULL COMMENT '联系人',
`cust_phone` VARCHAR(64) DEFAULT NULL COMMENT '固定电话',
`cust_mobile` VARCHAR(16) DEFAULT NULL COMMENT '移动电话',
PRIMARY KEY (`cust_id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
3 Customer实体
package www.test.domain;

3 书写orm元数据(对象与表的映射配置文件)

5.书写代码测试
package www.test.a_hello;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;
import www.test.domain.Customer;
// 测试hibernate 框架
public class Demo {
@Test
//保存客户
public void fun1(){
Configuration conf = new Configuration().configure();
SessionFactory sessionFactory = conf.buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
//-----------------
Customer customer = new Customer();
customer.setCust_name("百度公司");
session.save(customer); //执行保存
//--------------------
tx.commit();
session.close();
sessionFactory.close();
}
}
