但是当我启动时会报如下错误，具体原因在网上找出，应该是注入的变量必须是接口类型，但是我的已经指定为接口类型，请大家帮看下，谢谢，具体错误如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uAction': Injection of resource fields failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uFacade': Injection of resource fields failed; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'uService' must be of type [com.xxx.xxx.xxx.xxx.IUService], but was actually of type [$Proxy32]
