Docker Eureka未知后异常

我正在尝试使用停靠的springboot应用程序来实现微服务体系结构

对于内部通信，我想使用Eureka+佯装客户端。向Eureka works fine（afaik）注册：

调用该方法时，会出现以下异常：

account_1               | 2017-06-13 09:55:35.654 ERROR 1 --- [nio-6000-exec-6] o.a.c.c.C.[.[.[.[dispatcherServlet]      : Servlet.service() for servlet [dispatcherServlet] in context with path [/accounts] threw exception [Request processing failed; nested exception is com.netflix.hystrix.exception.HystrixRuntimeException: createUser failed and no fallback available.] with root cause
account_1               |
account_1               | java.net.UnknownHostException: auth-service

---

注册的IP是正确的，我只是想知道为什么他不知道“身份验证服务”。所以我猜他可能根本就没试着和尤里卡说话？我怎样才能以这种方式进行调试？

您是否执行了

@enablefignclients

？重新启动应用程序怎么样？您的客户端应用程序上是否有

@EnableDiscoveryClient

？类路径中是否有org.springframework.cloud:springcloudstartereureka？

FeignClient(name = "auth-service")
public interface AuthServiceClient {

  @RequestMapping(method = RequestMethod.POST, value = "/users", consumes = MediaType.APPLICATION_JSON_UTF8_VALUE)
  void createUser(User user);
}
