业务接口

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

业务实现层

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

 

控制层

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

简单说**解

  1、DAO层注解@Repository  

 2、Controller层注解@Controller

 3、Service层注解@Service

4   @Component组件注解

 

网上找了很多资料多有

         1、web.xml文档的配置不对,

         2、 bean配置的不正确或漏掉,

         3、@Service注解使用不当的或漏掉

我这个是maven的pom.xml配置的时候少了一些扎包和插件类,造成冲突和依赖不够。
