• 问题原因：

依赖冲突

项目主pom文件中引入了mybatis-plus-boot-start依赖，版本为3.5.3

    com.baomidou    mybatis-plus-boot-starter    3.5.3

业务包中引入mybatis-plus代码生成器依赖版本为3.4.1

     com.baomidou     mybatis-plus-generator     3.4.1

导致mybatis-plus-core核心包存在两个版本，导致冲突

•  解决办法

修改业务包中mybatis-plus代码生成器依赖版本为3.5.3，刷新Maven即可解决。
