mybatis整合ss的時候，無法autowire使用mapper的自動注入，找不到bean：NoSuchBeanDefinitionException

  
  
  
          

   
   
   
           
org.springframework.beans.factory.BeanCreationException: 
   
   
   
           

   
   
   
           

   
   
   
           
Error creating bean with name 'userDaoImpl': Injection of autowired dependencies failed; 
   
   
   
           

   
   
   
           

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

   
   
   
           

   
   
   
           

   
   
   
           
Could not autowire field: private com.dao.UserMapper com.service.UserDaoImpl.userMapper; 
   
   
   
           

   
   
   
           

   
   
   
           

   
   
   
           
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.dao.UserMapper] 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，在spring的配置文件中掃不到mapper下的dao文件們，可能就是路徑寫錯了。

我的原因是：路徑多了一個classpath：

所以把classpath去掉就好了。
