4.EA生成带注释的DDL语句，导入MySQL数据库
1.新建项目
2.新建数据库模型
3.添加元素（添加数据表）
4.设计字段
4.1注意：如果想让主键自增，实现在代码中id自增的效果，记得修改主键字段配置
5.导出DDL
6.导入数据库
6.1关于创建时间和修改时间自动填充更新的问题
要实现Java程序在插入数据时自动填充创建时间，在修改数据时自动填充修改时间，需要改一下相关字段的默认值
6.1.1 在新建表时配置
自动获取创建时间：timestamp not null default CURRENT_TIMESTAMP
自动获取更新时间：timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP
create table test(
id integer not null auto_increment primary key,
name varchar(20) not null ,
create_time timestamp not null default CURRENT_TIMESTAMP COMMENT '创建时间',
update_time timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP COMMENT '更新时间');

6.1.2 在修改现有表时配置
1用sql语句改
ALTER TABLE test MODIFY create_time timestamp not null default CURRENT_TIMESTAMP COMMENT '创建时间';
ALTER TABLE test MODIFY update_time timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP COMMENT '更新时间';

2用客户端改
创建时间默认值设为CURRENT_TIMESTAMP
修改时间默认值设为CURRENT_TIMESTAMP，同时勾选“根据当前时间戳更新”
5.将MySQL数据库导入到EA
1.下载安装mysql-connector-odbc
下载地址：https://download.csdn.net/download/weixin_44330367/89154248
根据使用的mysql版本选择对应的驱动进行安装（尽量选择32位的），傻瓜式安装过程省略
2.在管理工具中新增ODBC数据源
3.在EA中新建项目
4.链接MYSQL数据源
4.1 安装64位的ODBC驱动可能出现”在连接ODBC 时发生错误，请相关检查设置“的提示，卸载后重新安装32位ODBC驱动后可以正常执行
6.导入MYSQL的数据库
