hibernate入门程序

发布时间:2023-09-06 01:06责任编辑:郭大石关键词:暂无标签

快速入门

      1. 下载Hibernate框架的开发包

      2. 编写数据库和表结构

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(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!
