前言

最近项目中用到了Mybatis的通用代码生成器mybatis-generator，记起之前记录过的一篇文章
mybatis 生成代码配置 mybatis-generator:generate 的使用详解，用的是同一套东西，只是对比起之前添了一点东西

1、开发工具Eclipse -> Idea
2、添加Lombok模块
3、模块配置

之前的博客名也改为了SpringBoot - 集成 MyBatis 通用代码生成器 mybatis-generator（Eclipse篇），新旧实现，有需要的可对比看看

环境

Mysql + IDEA
SpringBoot2.5.4 + Mybatis2.1.5

具体实现

代码配置

注：上述代码中的模板变量引用自config.properties

• resources/generator/config.properties

jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/user_center?useSSL=false&serverTimezone=UTC&characterEncoding=UTF-8&nullCatalogMeansCurrent=true
jdbc.user=root
jdbc.password=sunday

# 模块名称
moduleName=user
# 表名
tableName=user

注：nullCatalogMeansCurrent=true是避免Mybatis Generator生成文件的时使用Mysql数据库的同名数据表

运行

• Maven-》项目-》Plugins-》mybatis-generator下双击运行即可

• 控制台日志

• 生成代码如下
