使用 Java 和 Amazon S3 管理大型亞馬遜SQS消息

您可以使用適用於 Java 的 Amazon SQS 擴展客戶端庫和 Amazon 簡單存儲服務(Amazon S3)來管理大型 Amazon 簡單隊列服務(亞馬遜SQS)消息。這對於消耗 256 KB 和最大 2 GB 的大型訊息承載特別有用。程式庫會將訊息承載儲存至 Amazon S3 儲存貯體,並將包含已存 Amazon S3 物件參考的訊息傳送至 Amazon SQS 佇列。

您可以使用適用於 Java 的 Amazon SQS 擴展客戶端庫來執行以下操作:

  • 指定訊息是否一律儲存在 Amazon S3,或僅儲存大小超過 256 KB 的訊息。

  • 傳送會參考儲存在 S3 儲存貯體內的單一訊息物件的訊息。

  • 從 Amazon S3 存儲桶中檢索消息對象

  • 從 Amazon S3 存儲桶中刪除消息對象

必要條件

下列範例使用 AWS 爪哇SDK。若要安裝和設定SDK,請參閱設定 AWS SDK對於 Java 中的 AWS SDK for Java 開發人員指南

在執行範例程式碼之前,請先設定您的 AWS 認證。如需詳細資訊,請參閱設定 AWS 認證和發展區域 AWS SDK for Java 開發人員指南

Java 和 Amazon SQS 擴展用戶端程式庫需要 J2SE 開發套件 8.0 或更新版本。SDK

注意

您可以使用 Amazon SQS 擴展用戶端程式庫使用 Amazon S3 來管理亞馬遜SQS訊息,有在 AWS SDK for Java。 你不能這樣做 AWS CLI,Amazon SQS 控制台 SQS HTTPAPI,Amazon 或任何其他 AWS SDKs.

AWS SDK對於 Java 1.x 示例:使用 Amazon S3 管理大型 Amazon SQS 消息

如下所示 AWS SDKJava 1.x 範例會使用隨機名稱建立 Amazon S3 儲存貯體,並新增生命週期規則以在 14 天後永久刪除物件。它也會建立名為的佇列,MyQueue並將存放在 Amazon S3 儲存貯體且超過 256 KB 的隨機訊息傳送至佇列。最後,程式碼會擷取該訊息,傳回訊息的相關資訊,接著刪除訊息、佇列和儲存貯體。

您可以使用 Apache Maven 為您的 Java 項目配置和構建 Amazon SQS 擴展客戶端,或者構建SDK自己。指定您在應用程SDK式中使用的個別模組。
