Object Storage Service：列舉資料管道（Java SDK V2）

前提條件

• 已安裝 OSS Java SDK V2。使用 Maven 時，請在 pom.xml 中添加依賴 com.aliyun:alibabacloud-oss-v2。

• 已通過環境變數配置訪問憑證。本文樣本使用 EnvironmentVariableCredentialsProvider 從環境變數 OSS_ACCESS_KEY_ID 和 OSS_ACCESS_KEY_SECRET 讀取憑證。

• 資料管道（DataPipeline）相關介面由 OSS 透傳至底層工作流程服務，請確保源通用 Bucket、目標向量 Bucket 位於同一地區。
