私は春のクラウドサービスを構築し、eureka、user-service（spring-data-rest user api）、およびfeign-clientサービスを含みます。

偽のクライアントで:

@FeignClient("useraccount")
public interface UserFeign {
    @RequestMapping(method=RequestMethod.POST,value="/users",consumes = "application/json")
    void createUser(@RequestBody User user);
    @RequestMapping(method=RequestMethod.DELETE,value="/users/{id}")
    void delById (@PathVariable("id") String id);

user-service api を呼び出して、feign-client でユーザーの削除と保存を実装したいと考えています。だから、私は残りのコントローラを作成します（jsはそれらにデータを転送します）：

@Autowired
    private UserFeign userFeign;

//save controller 

@RequestMapping(method = RequestMethod.POST, value = "/property/register")
    public  ResponseEntity<?>  createUser(@RequestBody User user) {
            userSaveFeign.createUser(user);
            return   ResponseEntity.ok();
    }


// and delete controller 

@RequestMapping(method = RequestMethod.DELETE, value = "/property/{id}")
    public String hello(@PathVariable("id") String id){
            userSaveFeign.delById(id);
        }
        return "hello";
    }

しかし、常にエラーが発生しました:

上記のストアと削除の方法には問題があるかもしれませんが、誰が私に正しいか、それ以上のことを教えてくれますか?

これは実際の例外ではありません。タイムアウトの理由を見つける必要があります。ロギングを有効にすると、失敗する理由を確認できます。

import org.springframework.context.annotation.Bean;

import feign.Logger;

public class FeignConfiguration {

    @Bean
    Logger.Level feignLoggerLevel() {
        return Logger.Level.FULL;
    }
}

また、サーバーがまったく解決されているかどうかも確認してください。ログは次のようになります。
