Java Google BigQuery套接字超时

我正在通过JavaAPI从BigQuery下载一个大型查询结果集

大约1小时后，基础套接字关闭，导致SocketException错误，查询失败

如何延长套接字超时，或者最好禁用它？ 以下是我建立联系的方式

  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();

InputStream credentialsJSON=新文件InputStream（“path.json”）；
NetHttpTransport=新的NetHttpTransport（）；
JsonFactory JsonFactory=新的JacksonFactory（）；
GoogleCredential credential=GoogleCredential.fromStream（credentialsJSON，transport，jsonFactory）；
credential.setExpiresInSeconds（空）；
//如果需要，插入BigQuery范围。
if（credential.createScopedRequired（））{
集合bigqueryScopes=bigqueryScopes.all（）；
凭证=凭证.createScoped（bigqueryScopes）；
}
返回新的Bigquery.Builder（传输、jsonFactory、凭证）
.setApplicationName（“ETL”）
.build（）；

}

好的，我通过覆盖其初始化器来延长HTTP超时时间，从而解决了这个问题

  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();
    }

私有静态HttpRequestInitializer setHttpTimeout（最终HttpRequestInitializer请求初始值设定项）{
返回新的HttpRequestInitializer（）{
@凌驾
公共无效初始化（HttpRequest HttpRequest）引发IOException{
初始化（httpRequest）；
httpRequest.setConnectTimeout（5*60000）；//5分钟连接超时
httpRequest.setReadTimeout（360*60000）；//120分钟读取超时
}
};
}
私有静态Bigquery createAuthorizedClient（）引发IOException{
InputStream credentialsJSON=新文件InputStream（“src/main/java/Warehouse/Common/googlecredentials.json”）；
NetHttpTransport=新的NetHttpTransport（）；
JsonFactory JsonFactory=新的JacksonFactory（）；

//如果需要，插入BigQuery范围。
if（credential.createScopedRequired（））{
集合bigqueryScopes=bigqueryScopes.all（）；
凭证=凭证.createScoped（bigqueryScopes）；
}
返回新的Bigquery.Builder（传输、jsonFactory、setHttpTimeout（凭证））
