Injection of autowired dependencies failed解决方式

异常如下:

ERROR [RMI TCP Connection(3)-127.0.0.1] - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'orderItemServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.luckincoffee.commodity.service.ProductService com.luckincoffee.commodity.service.impl.OrderItemServiceImpl.productService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.luckincoffee.commodity.service.ProductService] 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)}

首先检测是否少@Service,如上图位置.

其次,删除abstract,便可解决异常,如果仍旧报错,下一步:

删除Service层的未使用接口.
