今天测试spring、springmvc、mybatis，分层为dao、service、serviceimpl、controller，在运行的时候提示

1 org.apache.catalina.core.ApplicationContext.log StandardWrapper.Throwable2  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'XXXController':      Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:      No matching bean of type [com.XX.service.IXXService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.      Dependency annotations: {@javax.annotation.Resource(shareable=true, lookup=, name=, description=, authenticationType=CONTAINER, type=class java.lang.Object, mappedName=)}3     at org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.postProcessPropertyValues(CommonAnnotationBeanPostProcessor.java:306)4     at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1106)5     at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:517)6     at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:456)

 

我所有的注解都已经写好的：

dao   @Repository

serviceimpl     @Service

controller    @Controller

 

并且spring配置文件也写好自动扫描，位置也正确。但错误一直都在

 

 

折腾了一晚上才发现，spring监听配置被注释掉了

在web.xml里面还原spring的监听配置

1  
     
      2         
      
       org.springframework.web.context.ContextLoaderListener
      3     
     4     
     
      5         
      
       org.springframework.web.util.IntrospectorCleanupListener
      6     
     

 

然后问题解决了
