一、该问题的重现步骤是什么？

1. 我尝试着使用Feign的Okhttp进行服务调用，但是项目启动失败！


二、你期待的结果是什么？实际看到的又是什么？

我希望能够调用Feign的时候能够使用Okhttp去建立服务连接。


三、你正在使用的是什么产品，什么版本？在什么操作系统上？

我正在使用BladeX的

2.5.0.RELEASE

系统：win10


四、请提供详细的错误堆栈信息，这很重要。

五、若有更多详细信息，请在下面提供。

1、配置方式：yaml配置

image.png

2、引入配置类FeignConfig

(Feign.)
(FeignAutoConfiguration.)
FeignConfig {
Contract feignContract() {
      feign.Contract.Default();
   }


   ({Client.})
   Client feignClient(okhttp3.OkHttpClient client) {
      feign.okhttp.OkHttpClient(client);
   }

   ({ConnectionPool.})
   ConnectionPool httpClientConnectionPool(FeignHttpClientProperties httpClientProperties, OkHttpClientConnectionPoolFactory connectionPoolFactory) {
      Integer maxTotalConnections = httpClientProperties.getMaxConnections();
      Long timeToLive = httpClientProperties.getTimeToLive();
      TimeUnit ttlUnit = httpClientProperties.getTimeToLiveUnit();
      connectionPoolFactory.create(maxTotalConnections, timeToLive, ttlUnit);
   }

   OkHttpClient client(OkHttpClientFactory httpClientFactory, ConnectionPool connectionPool, FeignHttpClientProperties httpClientProperties) {
      Boolean followRedirects = httpClientProperties.isFollowRedirects();
      Integer connectTimeout = httpClientProperties.getConnectionTimeout();
      Boolean disableSslValidation = httpClientProperties.isDisableSslValidation();
      httpClientFactory.createBuilder(disableSslValidation)
         .connectTimeout(()connectTimeout, TimeUnit.)
         .followRedirects(followRedirects)
         .connectionPool(connectionPool)
         .addInterceptor(OkHttpLogInterceptor()) .build();
   }
}

3、引入日志拦截器

OkHttpLogInterceptor Interceptor {


   Response intercept(Interceptor.Chain chain) IOException {
      Request request = chain.request();

      t1 = System.();.info(String.(,
         request.url(), chain.connection(), request.headers()));

      Response response = chain.proceed(request);

      t2 = System.();ResponseBody responseBody = response.peekBody(* );

      .info(String.(,
         response.request().url(),
         responseBody.string(),
         (t2 - t1) / ,
         response.headers()));

      response;
   }
}
5、引入okhttp依赖
<dependency>
    <groupId>io.github.openfeign</groupId>
    <artifactId>feign-okhttp</artifactId>
    <version>10.2.0</version>
</dependency>
