在 Amazon S3 Glacier 中使用AWS SDK for Java配置文件库通知

以下是使用AWS SDK for Java低级 API 在文件库中配置通知的步骤。

  1. 创建 AmazonGlacierClient 类(客户端)的实例。

    您需要指定文件库所在的 AWS 区域。您使用此客户端执行的所有操作都会应用到该区域。

  2. 通过创建一个 SetVaultNotificationsRequest 类的实例提供通知配置信息。

    您需要提供文件库名称、通知配置信息和账户 ID。在指定通知配置时,您可以提供一个现有的 Amazon SNS 主题的Amazon 资源名称 (ARN),以及您希望获得其通知的一个或多个事件。有关受支持的事件的列表,请参阅“设置文件库通知配置(设置通知配置)”。

  3. 以参数形式提供请求数据元,以执行 setVaultNotifications 方法。

以下 Java 代码段说明了前面的步骤。该代码段在文件库中设置了通知配置。当 ArchiveRetrievalCompleted 事件或 InventoryRetrievalCompleted 事件发生时,该配置会请求 Amazon S3 Glacier (Glacier) 向指定的 Amazon SNS 主题发送通知。

SetVaultNotificationsRequest request = new SetVaultNotificationsRequest() .withAccountId("-") .withVaultName("*** provide vault name ***") .withVaultNotificationConfig( new VaultNotificationConfig() .withSNSTopic("*** provide SNS topic ARN ***") .withEvents("ArchiveRetrievalCompleted", "InventoryRetrievalCompleted") ); client.setVaultNotifications(request);

示例:使用AWS SDK for Java在文件库中设置通知配置

以下 Java 代码示例设置了文件库的通知配置并删除了配置,然后恢复了配置。有关如何运行以下示例的分步说明,请参阅“将AWS SDK for Java与 Amazon S3 Glacier 结合使用”。
