解决org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'c

添加注解@Autowired显红，但是代码没有报错，原因可能是没有注入依赖.

运行后的报错信息如下：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.lzy.weixinsell.service.impl.ProductServiceImplTest': Unsatisfied dependency expressed through field 'productService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.lzy.weixinsell.service.impl.ProductServiceImpl' available: expected at least 1 bean which qualifies as autowire candidate.

解决方法

需要在类ProductServiceImpl添加@Service
