Question

我正在通过Java API从BigQuery下载一个大型查询结果集。

大约1小时后，底层套接字关闭，导致SocketException错误，查询失败。

如何延长套接字超时，或者最好禁用套接字超时？以下是我建立连接的方式。

  InputStream credentialsJSON = new FileInputStream("path.json");


  NetHttpTransport transport = new NetHttpTransport();
  JsonFactory jsonFactory = new JacksonFactory();
  GoogleCredential credential = GoogleCredential.fromStream(credentialsJSON, transport, jsonFactory);
  credential.setExpiresInSeconds(null);

  // Inject the BigQuery scope if required.
  if (credential.createScopedRequired()) {
      Collection<String> bigqueryScopes = BigqueryScopes.all();
      credential = credential.createScoped(bigqueryScopes);
  }

  return new Bigquery.Builder(transport, jsonFactory, credential)
          .setApplicationName("ETL")
          .build();

}

好的，我通过覆盖其初始化来扩展HTTP超时来解决这个问题。

  private static HttpRequestInitializer setHttpTimeout(final HttpRequestInitializer requestInitializer) {
    return new HttpRequestInitializer() {
        @Override
        public void initialize(HttpRequest httpRequest) throws IOException {
           requestInitializer.initialize(httpRequest);
           httpRequest.setConnectTimeout(5 * 60000);  // 5 minutes connect timeout
           httpRequest.setReadTimeout(360 * 60000);  // 120 minutes read timeout
        }
        };
   }





    private static Bigquery createAuthorizedClient() throws IOException {

        InputStream credentialsJSON = new FileInputStream("src/main/java/Warehouse/Common/GoogleCredential.json");


        NetHttpTransport transport = new NetHttpTransport();
        JsonFactory jsonFactory = new JacksonFactory();
        GoogleCredential credential = GoogleCredential.fromStream(credentialsJSON, transport, jsonFactory);

        // Inject the BigQuery scope if required.
        if (credential.createScopedRequired()) {
            Collection<String> bigqueryScopes = BigqueryScopes.all();
            credential = credential.createScoped(bigqueryScopes);
        }

        return new Bigquery.Builder(transport, jsonFactory, setHttpTimeout(credential))
                .setApplicationName("ETL")
                .build();
    }
