我正在尝试使用Jclouds将文件上传到Azure BLOB。运行服务器的环境是Microsoft Windows Azure VM，该环境在专用网络上运行。它具有通过防火墙打开的端口80和443。以下代码用于上传文件。如果我从PC执行相同的代码，则该代码可以正常工作：
@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.

为了使这项工作能够在Azure VM上进行任何配置吗？请帮忙。
最佳答案
您是否正在使用Java 7u51运行jclouds 1.6.x或1.7.0？如果是这样，您可能遇到了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。
另外，您应该更喜欢ByteSource Payload而不是FileInputStream，因为前者允许jclouds重试逻辑起作用。您可以使用Files.asByteSource(File)创建一个。
