List data pipelines (Java SDK V2)

Prerequisites

• OSS Java SDK V2 is installed. If you use Maven, add the com.aliyun:alibabacloud-oss-v2 dependency to your pom.xml.

• Access credentials are configured by using environment variables. The example in this topic uses EnvironmentVariableCredentialsProvider to read credentials from the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables.

• DataPipeline operations are forwarded by OSS to the underlying workflow service. Make sure that the source standard bucket and the destination vector bucket are located in the same region.

Sample code

import com.aliyun.sdk.service.oss2.credentials.CredentialsProvider;
import com.aliyun.sdk.service.oss2.credentials.EnvironmentVariableCredentialsProvider;
import com.aliyun.sdk.service.oss2.dataprocess.OSSDataProcessClient;
import com.aliyun.sdk.service.oss2.dataprocess.models.*;

public class ListDataPipelineConfigurationsSample {
    public static void main(String[] args) throws Exception {
        CredentialsProvider provider = new EnvironmentVariableCredentialsProvider();
        try (OSSDataProcessClient client = OSSDataProcessClient.newBuilder()
                .region("cn-hangzhou")
                .credentialsProvider(provider)
                .build()) {

            String nextToken = null;
            do {
                ListDataPipelineConfigurationsRequest.Builder reqBuilder =
                        ListDataPipelineConfigurationsRequest.newBuilder().maxResults(100);
                if (nextToken != null) {
                    reqBuilder.nextToken(nextToken);
                }

                ListDataPipelineConfigurationsResult result =
                        client.listDataPipelineConfigurations(reqBuilder.build());

                System.out.printf("Status code:%d, request id:%s%n",
                        result.statusCode(), result.requestId());

                if (result.dataPipelineConfigurations() != null) {
                    for (DataPipelineConfiguration cfg : result.dataPipelineConfigurations()) {
                        System.out.printf("Pipeline: name=%s, status=%s, createTime=%s%n",
                                cfg.dataPipelineName(), cfg.status(), cfg.createTime());
                    }
                }

                nextToken = result.nextToken();
            } while (nextToken != null && !nextToken.isEmpty());

        } catch (Exception e) {
            System.out.printf("error:%n%s", e);
        }
    }
}
