在學習Spring-boot-mybatis時，報錯A component required a bean of type 'com.sirifeng.testmybatis.mapper.BookMapper' that could not be found.
后來發現是在啟動器上沒有添加注解
@MapperScan("com.sirifeng.testmybatis.mapper")
如有這個錯誤的可以看一下是不是因為這個原因。
Java報錯: A component required a bean of type 'com.sirifeng.testmybatis.mapper.BookMapper' that could not be found.
