登时入门

      一. 下载Hibernate框架的开垦包

      2. 编辑数据库和表结构

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(3贰) NOT NULL COMMENT ‘客户名称(集团名称)’,*

*  `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(3二) DEFAULT NULL COMMENT ‘客户音讯来源’,*

*  `cust_industry` varchar(3贰) DEFAULT NULL COMMENT ‘客户所属行当’,*

*  `cust_level` varchar(3贰) DEFAULT NULL COMMENT ‘客户等第’,*

*  `cust_linkman` varchar(64) DEFAULT NULL COMMENT ‘联系人’,*

*  `cust_phone` varchar(6四) DEFAULT NULL COMMENT ‘固定电话’,*

*  `cust_mobile` varchar(1陆) DEFAULT NULL COMMENT ‘移动电话’,*

*  PRIMARY KEY (`cust_id`)*

) ENGINE=InnoDB AUTO_INCREMENT=94 DEFAULT CHARSET=utf8;

 

      ③. 创办WEB的品类,导入了花费的jar包

           *
MySQL驱动包、Hibernate开采的必要求有个别jar包、日志的jar包

      四. 编辑JavaBean,以往不应用基本数据类型,使用包装类 

      伍.
编纂映射的配备文件(主旨),起先入开荒的自律,里面平常配备标签

      六. 编辑hibernate的大旨的配置文件,里面包车型地铁剧情是一向的

      7. 编写代码,使用的类和办法   

内需jar包的,留下邮箱!

高效入门

      1. 下载Hibernate框架的开辟包

      二. 编纂数据库和表结构

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(3二) NOT NULL COMMENT ‘客户名称(集团名称)’,*

*  `cust_user_id` bigint(32) DEFAULT NULL COMMENT ‘负责人id’,*

*  `cust_create_id` bigint(32) DEFAULT NULL COMMENT ‘创建人id’,皇冠现金app,*

*  `cust_source` varchar(3二) DEFAULT NULL COMMENT ‘客户消息来源’,*

*  `cust_industry` varchar(3贰) DEFAULT NULL COMMENT ‘客户所属行当’,*

*  `cust_level` varchar(32) DEFAULT NULL COMMENT ‘客户品级’,*

*  `cust_linkman` varchar(64) DEFAULT NULL COMMENT ‘联系人’,*

*  `cust_phone` varchar(6肆) DEFAULT NULL COMMENT ‘固定电话’,*

*  `cust_mobile` varchar(1陆) DEFAULT NULL COMMENT ‘移动电话’,*

*  PRIMARY KEY (`cust_id`)*

) ENGINE=InnoDB AUTO_INCREMENT=94 DEFAULT CHARSET=utf8;

 

      3. 创办WEB的品种,导入了支付的jar包

           *
MySQL驱动包、Hibernate开荒的总得要有的jar包、日志的jar包

      四. 编写制定JavaBean,以往不使用基本数据类型,使用包装类 

      5.
编辑映射的配备文件(核心),初步入开荒的自律,里面平常布署标签

      6. 编写制定hibernate的主干的布署文件,里面的内容是牢固的

      柒. 编写代码,使用的类和方法
