Java

试用此示例之前，请按照 BigQuery 快速入门：使用客户端库中的 Java 设置说明进行操作。如需了解详情，请参阅 BigQuery Java API 参考文档。

如需向 BigQuery 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为客户端库设置身份验证。

import com.google.cloud.bigquery.connection.v1.Connection;
import com.google.cloud.bigquery.connection.v1.ConnectionName;
import com.google.cloud.bigquery.connection.v1.GetConnectionRequest;
import com.google.cloud.bigqueryconnection.v1.ConnectionServiceClient;
import java.io.IOException;

// Sample to get connection
public class GetConnection {

  public static void main(String[] args) throws IOException {
    // TODO(developer): Replace these variables before running the sample.
    String projectId = "MY_PROJECT_ID";
    String location = "MY_LOCATION";
    String connectionId = "MY_CONNECTION_ID";
    getConnection(projectId, location, connectionId);
  }

  static void getConnection(String projectId, String location, String connectionId)
      throws IOException {
    try (ConnectionServiceClient client = ConnectionServiceClient.create()) {
      ConnectionName name = ConnectionName.of(projectId, location, connectionId);
      GetConnectionRequest request =
          GetConnectionRequest.newBuilder().setName(name.toString()).build();
      Connection response = client.getConnection(request);
      System.out.println("Connection info retrieved successfully :" + response.getName());
    }
  }
