使用 Amazon SDK for Java 在 Amazon S3 Glacier 中创建文件库 - Amazon S3 Glacier
Amazon Web Services 文档中描述的 Amazon Web Services 服务或功能可能因区域而异。要查看适用于中国区域的差异,请参阅 中国的 Amazon Web Services 服务入门 (PDF)

此页面仅适用于使用保管库的 S3 Glacier 服务的现有客户以及 2012 年以RESTAPI来的原始客户。

如果您正在寻找档案存储解决方案,我们建议您在亚马逊 S3、S3 Glacier 即时检索、S3 Glacier 灵活检索和 S3 Glacier Deep Archive Dee p Archive 中使用 S3 Glacier 存储类。要了解有关这些存储选项的更多信息,请参阅 Amazon S3 用户指南中的 S3 Glacier 存储类和使用 S3 Glacier 存储类的长期数据存储。这些存储类别使用 Amazon S3API,适用于所有区域,并且可以在 Amazon S3 控制台中进行管理。它们提供存储成本分析、存储镜头、高级可选加密功能等功能。

使用 Amazon SDK for Java 在 Amazon S3 Glacier 中创建文件库

该低级 API 为所有文件库操作提供了方法,包括创建和删除文件库、获取文件库描述,以及获取特定 Amazon Web Services 区域创建的文件库的列表。以下是使用Amazon SDK for Java创建文件库的步骤。

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

    您需要指定要创建文件库的 Amazon Web Services 区域。您使用此客户端执行的所有操作都会应用到该 Amazon Web Services 区域。

  2. 通过创建一个 CreateVaultRequest 类的实例提供请求信息。

    Amazon S3 Glacier (S3 Glacier) 要求您提供文件库名称和您的账户 ID。如果您不提供账户 ID,则系统会使用与您提供来对请求签名的证书相关联的账户 ID。有关更多信息,请参阅将 Amazon SDK for Java 与 Amazon S3 Glacier 结合使用

  3. 以参数形式提供请求对象,运行 createVault 方法。

    S3 Glacier 返回的响应在 CreateVaultResult 对象中提供。

以下 Java 代码段说明了前面的步骤。该代码段在 us-west-2 区域创建了文件库。它打印的 Location 是文件库的相对 URI,该 URI 包括您的账户 ID、Amazon Web Services 区域和文件库名称。

AmazonGlacierClient client = new AmazonGlacierClient(credentials); client.setEndpoint("https://glacier.us-west-2.amazonaws.com"); CreateVaultRequest request = new CreateVaultRequest() .withVaultName("*** provide vault name ***"); CreateVaultResult result = client.createVault(request); System.out.println("Created vault successfully: " + result.getLocation());

示例:使用 Amazon SDK for Java 创建文件库

以下 Java 代码示例在 us-west-2 区域创建了文件库(有关 Amazon Web Services 区域的更多信息,请参阅访问 Amazon S3 Glacier)。此外,该代码示例还检索了文件库信息,列出了同一 Amazon Web Services 区域的所有文件库,然后删除了创建的文件库。

有关如何运行以下示例的分步说明,请参阅“使用 Eclipse 运行 Amazon S3 Glacier 的 Java 示例”。
