无法使用 JClouds 将文件从 Microsoft Windows Azure VM 上传到 Azure BLOB

Question

我正在尝试使用 Jclouds 将文件上传到 Azure BLOB。服务器运行的环境是 Microsoft Windows Azure VM，它在专用网络上运行。它通过防火墙打开了端口 80 和 443。以下代码用于上传文件。如果我从我的 PC 执行相同的代码：

@SuppressWarnings("nls")
public boolean upload(final String path) 
{
    final File file = new File(path);

    FileInputStream fis = null;
    BlobStoreContext context =null;
    try
    {
        fis = new FileInputStream(file);

        context = ContextBuilder.newBuilder("azureblob").credentials(this.store, this.key).buildView(BlobStoreContext.class);

        final BlobStore store = context.getBlobStore();

        Payload payload = new InputStreamPayload(fis);
        payload.getContentMetadata().setContentLength(fis.getChannel().size());

        final Blob blob = store.blobBuilder(file.getName()).payload(payload).build();

        context.getBlobStore().putBlob("js-uc-osprey", blob);
        return true;
    }
    catch (Exception e) 
    {
        e.printStackTrace();
    }
    finally
    {
        if(context!=null)
        context.close();            
    }

    return false;
}

我得到以下异常：

com.google.inject.CreationException: Guice creation errors:

1) org.jclouds.rest.RestContext<org.jclouds.azureblob.AzureBlobClient, A> cannot be used as a key; It is not fully specified.

是否需要在 Azure VM 上进行任何配置才能完成这项工作？请帮忙。

Answer 1

您是在运行 jclouds 1.6.x 还是 1.7.0 和 Java 7u51？如果是这样，您可能遇到过 https://issues.apache.org/jira/browse/JCLOUDS-427 。您可以通过降级到 Java 7u45 或升级到 jclouds 1.7.1 来解决此问题。

此外，您应该更喜欢 ByteSource Payload 而不是 FileInputStream，因为前者允许 jclouds 重试逻辑工作。您可以使用Files.asByteSource(File) 创建一个。
