今天在创建接口的时候遇到了这么一个错
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eduVideoController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eduVideoServiceimpl': Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.czxy.mapper.EduVideoMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我先在controller找，然后向service层找，最后在mapper层找到了原因：
原来是在自动导包的时候导错位置了，导的是mapstruct的应该是apache.ibatis.annotations
最后成功执行了。
