请求超时

# feign配置
feign:
  httpclient:
    enabled: true # 默认开启
  client:
    config:
      default: # 默认全局服务调用超时配置
        connectTimeout: 2000 # 连接超时
        readTimeout: 2000 # 接口请求超时
      serviceAdmin: # 自定义服务调用超时配置
        connectTimeout: 100000
        readTimeout: 100000

OkHttpClient请求超时

        OkHttpClient client = new OkHttpClient.Builder()
                .connectTimeout(1, TimeUnit.SECONDS)
                .readTimeout(2, TimeUnit.SECONDS)
                .build();

        Request request = new Request.Builder()
                .url("http://127.0.0.1:8888/3PL/testHttp")
                .header("token", "token_9c33f844-ffb7-4765-88ae-258624a5f526")
                .get()
                .build();
        String message = null;
        String result = null;
        try {
            Response response = client.newCall(request).execute();
            if (!response.isSuccessful()) {
                throw new RuntimeException("请求失败");
            }
            message = response.message();
            result = response.body().string();
        } catch (SocketTimeoutException socketTimeoutException) {
            if ("connect timed out".equalsIgnoreCase(socketTimeoutException.getMessage())) {
                log.info("连接超时");
            }
        } catch (InterruptedIOException interruptedException) {
            if ("Read timed out".equalsIgnoreCase(interruptedException.getCause().getMessage())) {
                log.info("响应超时");
            }
