本文主要是介绍No qualifying bean of type tk.mybatis.mapper.common.Mapper，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
前言
springboot集成了tkMapper。现在在添加BaseService。
报错信息

错误：
启动项目报错：No qualifying bean of type ‘com.baomidou.mybatisplus.mapper.BaseMapper<?>’ available: expected single matching bean but found 4
解决：
将ServiceBaseImpl 更改为抽象类
ok
