Feign不解析名称

Question

我正在尝试使用Spring Cloud的Open Feign调用另一个服务，但以下是我不断得到的响应：

{
  "timestamp": 1579015052962,
  "status": 500,
  "error": "Internal Server Error",
  "message": "auth-service: Name or service not known executing GET http://auth-service/api/v1/auth",
  "path": "/api/v1/event"
}

下面是我的代码：

package com.eventmanager.events.client;

import com.eventmanager.events.client.mappings.Auth;
import com.eventmanager.events.config.CustomFeignClientConfig;
import com.eventmanager.events.responses.Response;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestHeader;

@FeignClient(name = "auth-service", configuration = CustomFeignClientConfig.class)
public interface AuthClient {
  @GetMapping("/api/v1/auth")
  public Response<Auth> getLoggedUser(@RequestHeader(value = "Authorization") String authorization);
}

我将Feign配置为使用OkHttp客户端，但我不确定是不是它导致了这个错误：

package com.eventmanager.events.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import feign.okhttp.OkHttpClient;

@Configuration
public class CustomFeignClientConfig {
  @Bean
  public OkHttpClient client() {
    return new OkHttpClient();
  }
}

如果你正在使用Finchey.SR1，你可以检查这个https://stackoverflow.com/a/52727544在那个云版本中的ContentPath似乎有一个问题。

Answer 2

可能是因为您尚未指定基URL。对于客户端&它将基本URL作为auth-service。

@FeignClient(name = "auth-service", configuration = CustomFeignClientConfig.class, url = "http://lcoalhost:8080")
public interface AuthClient {
  @GetMapping("/api/v1/auth")
  public Response<Auth> getLoggedUser(@RequestHeader(value = "Authorization") String authorization);
}
