spring cloud - How to safely have a @RestController class implementing an interface annotated with @FeignClient -

given following code sample

-- client library code

@feignclient("string-service") public interface stringclient {       @requestmapping(method = requestmethod.get, value = "/microservicestring")       public string home(); }   @service public class stringhystrixclient {      private final springclient springclient; //....  } 

-- service library code

@restcontroller public class stringcontroller implements stringclient {     public string home(){          return "world";     } }   @springbootapplication @enablehystrix @enableeurekaclient @enablefeignclients public class stringapplication { ....} 

if service library references client library, when application gets started, through component scanning state in filling dependencies stringhystrixclient, spring container not know because there 2 beans implementing stringclient.

one solution avoid not implement stringclient in stringcontroller, code duplication interface , rest controller error prone. can point out more elegant solution problem?
