在学习Spring-boot-mybatis时，报错A component required a bean of type 'com.sirifeng.testmybatis.mapper.BookMapper' that could not be found.
后来发现是在启动器上没有添加注解
@MapperScan("com.sirifeng.testmybatis.mapper")
如有这个错误的可以看一下是不是因为这个原因。
Java报错: A component required a bean of type 'com.sirifeng.testmybatis.mapper.BookMapper' that could not be found.
