前言
代码生成器模板 mybatis-plus + Freemarker+lombok模板引擎，自定义模板
导入相关依赖
<!-- 若要整合springboot，需要注意版本之间的问题 springboot版本对于mybatis-plus-boot-starter不兼容 ·-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.0.3</version>
</dependency>
<!--MyBatis-Plus逆向功能所需的模板引擎-->
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.30</version>
