bug解决_{@org.springframework.beans.factory.annotation.Autowired(required=true)}

问题:

org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'itemsController': 

Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:

 Could not autowire field: private com.itheima.springmvc.service.ItemsService com.itheima.springmvc.controller.ItemsController.itemsService;

 nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 

No qualifying bean of type [com.itheima.springmvc.service.ItemsService] 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)}

原因:没有加载spring核心配置文件

解决:在web.xml里面添加applicationContext.xml相关配置就解决了
