Caused by: org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'authUserServiceImpl': Injection of autowired dependencies failed; 

nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.online.college.core.auth.dao.AuthUserDao com.online.college.core.auth.service.impl.AuthUserServiceImpl.entityDao; 

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.online.college.core.auth.dao.AuthUserDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. 

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

貌似找不到接口AuthUserDao的实现类。

恳请帮忙，非常感谢！
