在整合ssm框架，测试service层的时候报错

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [dx.service.ItemService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这里是service依赖注入失败，后来发现在applicationContext.xml要配置

  <context:annotation-config />
    <context:component-scan base-package="dx.service" />

springmvc.xml里面也要配置

      
        <!-- 扫描@Controler  @Service   -->
        <context:component-scan base-package="dx"/>

然后问题就解决了。

ps:初学者记录
