- 配置数据连接
- 填写一个连接名，随便填什么都行
- 不用选择，默认就行
- 填写数据库连接的 IP地址，比如本地数据库可以填写：localhost或者127.0.0.1
- 填写数据库开放的端口号，一般没设置的话默认都是3306
- 填写你需要连接的数据库名
- 填写数据库的用户名
- 填写数据库密码
- 这里会有一个驱动需要点击下载，图中是已经下载好了
- 填写自己的数据库连接url，然后可以点击9所在按钮进行测试连接，本地连接失败检查是否开启了mysql服务
2.配置Generate POJOs.groovy配置
如果只是创建简单的, 只有属性, getter, setter的实体类, 而不需要JPA/Hibernate的实体类注解
1. 单击打开刚刚创建的数据连接
2. 打开schemas, 找到自己需要创建实体类的表(可以使用ctrl或shift多选)
3. 右键: Scripted Extensions - Generate POJOs.groovy
4. 选择生成路径就OK了
+ **需注意**
+ 生成的包名可能有问题, 默认是`package com.sample`, 需要自己手动修改
选择表然后自定义配置脚本操作

新建一个文件将上面的脚本复制到其中保存 MyPOJOs.groovy是我zi'ji自己建的
