Error creating bean with name 'itemCatController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.taotao.service.ItemCatService com.taotao.controller.ItemCatController.itemCatService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.taotao.service.ItemCatService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
