mybatis整合ss的时候，无法autowire使用mapper的自动注入，找不到bean：NoSuchBeanDefinitionException

1. 1. org.springframework.beans.factory.BeanCreationException:
   4. Error creating bean with name ‘userDaoImpl‘: Injection of autowired dependencies failed;
   7. nested exception is org.springframework.beans.factory.BeanCreationException:
   11. Could not autowire field: private com.dao.UserMapper com.service.UserDaoImpl.userMapper;
   15. 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的配置文件中扫不到mapper下的dao文件们，可能就是路径写错了。

我的原因是：路径多了一个classpath：

所以把classpath去掉就好了。
