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

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

import org.hibernate.cfg.Configuration;

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();
