SpringBoot - 集成 MyBatis 通用代码生成器 mybatis-generator（IDEA篇）
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

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
