faign不解析名称

Question

我正在尝试使用Spring Cloud的Open Faign调用另一个服务，但我一直得到以下回应：

{
  "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"
}

这是我的密码：

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);
}

我已将Faign配置为使用OkHttp客户端，但我不确定它是否对错误负责：

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();
  }
}

Answer 1

可能是因为您没有为客户端指定基本URL。

@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);
}

如果你用的是芬奇。SR1，你可以检查一下https://stackoverflow.com/a/52727544该云版本中的ContentPath似乎存在问题。
