在使用feign时出现No qualifying bean of type []found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

No qualifying bean of type [] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

启动时出现，是因为接口没有实现类，这个问题怎么解决？还是说feign不是这么用的？谢谢！
