关于springboot启动报错：Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Description:

Field studentDAO in com.example.springbootstucourse.service.StuServiceImpl required a bean of type 'com.example.springbootstucourse.dao.StudentDAO' that could not be found.

Action:

Consider defining a bean of type 'com.example.springbootstucourse.dao.StudentDAO' in your configuration.

解决办法：在指定的application类上加上这么一行注解，手动指定application类要扫描哪些包下的注解

参考：关于spring boot自动注入出现Consider defining a bean of type 'xxx' in your configuration问题解决方案
