springboot项目

在springboot项目整合时出现这样的错误：

Description:

A component required a bean of type 'com.briup.apps.app02.dao.CourseMapper' that could not be found.

Action:

Consider defining a bean of type 'com.briup.apps.app02.dao.CourseMapper' in your configuration.

Process finished with exit code 0

解决方案：

可以用@MapperScan在Application中注入com.briup.apps.app02.dao注解@MapperScan(value = {"com.briup.apps.app02.dao"})
