使用 Java 和 Amazon S3 管理大型亚马逊SQS消息
您可以使用适用于 Java 的亚马逊SQS扩展客户端库
您可以使用适用于 Java 的 Amazon SQS 扩展客户端库来执行以下操作:
-
指定消息是始终存储在 Amazon S3 中还是仅在其大小超过 256 KB 时存储在 Amazon S3 中。
-
发送引用存储在 S3 存储桶中的单个消息对象的消息
-
从 Amazon S3 存储桶中检索消息对象
-
从 Amazon S3 存储桶中删除消息对象
先决条件
以下示例使用 AWS Java SDK。要安装和设置SDK,请参阅设置 AWS SDK适用于 Java 中的 AWS SDK for Java 开发者指南。
在运行示例代码之前,请配置您的 AWS 证书。有关更多信息,请参阅设置 AWS 该领域的资质和发展区域 AWS SDK for Java 开发者指南。
SDK适用于 Java
注意
您只能使用适用于 Java 的 Amazon SQS 扩展客户端库通过 Amazon S3 管理亚马逊SQS消息 AWS SDK for Java。 你不能用 AWS CLI、Amazon SQS 控制台SQSHTTPAPI、Amazon 或任何其他 AWS SDKs.
AWS SDK适用于 Java 1.x 示例:使用亚马逊 S3 管理大型亚马逊消息 SQS
以下 AWS SDK适用于 Java 1.x 的示例使用随机名称创建一个 Amazon S3 存储桶,并添加一条生命周期规则,以便在 14 天后永久删除对象。它还会创建一个名为的队列MyQueue
并向该队列发送一条存储在 Amazon S3 存储桶中且超过 256 KB 的随机消息。最后,代码会检索该消息,返回该消息的相关信息,并删除该消息、队列和存储桶。

您可以使用 Apache Maven 为您的 Java 项目配置和构建 Amazon SQS 扩展客户端,也可以自行构建。SDK从中指定您在应用程序中使用的各个模块。SDK
