1. 下载Hibernate框架的开发包
2. 编写数据库和表结构
class="a">Create database hibernate_day01;
Use hibernate_day01;
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_user_id` bigint(32) DEFAULT NULL COMMENT '负责人id',
`cust_create_id` bigint(32) DEFAULT NULL COMMENT '创建人id',
`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=94 DEFAULT CHARSET=utf8;
3. 创建WEB的项目，导入了开发的jar包
* MySQL驱动包、Hibernate开发的必须要有的jar包、日志的jar包
4. 编写JavaBean，以后不使用基本数据类型，使用包装类
5. 编写映射的配置文件（核心），先导入开发的约束，里面正常配置标签
6. 编写hibernate的核心的配置文件，里面的内容是固定的
7. 编写代码，使用的类和方法
需要jar包的，留下邮箱！
