我是Azure的新手，我正在将azure-storage-blob v11.0.0用于Java，并按照此处的示例https://github.com/Azure-Samples/storage-blob-java-getting-started
尝试上传文件这是按预期方式上传的，但是我的应用程序仍然处于活动状态，似乎存在远程套接字超时，这将导致生成和异常：

我仍然可以使用该应用程序并执行其他上载操作，但是我不确定是否必须清除任何未使用的连接。或者，如果我可以忽略这些错误。
编辑：添加了使用的代码示例
public class AzureCopy
{
private final ContainerURL containerURL;
public AzureCopy() throws InvalidKeyException, MalformedURLException
{
final String accountName = ConfHelper.getString("AZURE_ACCOUNT");
final String accountKey = ConfHelper.getString("AZURE_KEY");
final SharedKeyCredentials creds = new SharedKeyCredentials(accountName, accountKey);
final ServiceURL serviceURL = new ServiceURL(new URL("https://" + accountName + ".blob.core.windows.net"), StorageURL.createPipeline(creds, new PipelineOptions()));
containerURL = serviceURL.createContainerURL(ConfHelper.getString("AZURE_CONTAINER"));
}
public void upload(final File toUpload)
{
if(toUpload != null)
{
final BlockBlobURL blobURL = containerURL.createBlockBlobURL(toUpload.getName());
try
{
uploadFile(blobURL, toUpload);
}
catch(final IOException e)
{
e.printStackTrace();
}
}
}
private static void uploadFile(final BlockBlobURL blob, final File sourceFile) throws IOException
{
final AsynchronousFileChannel fileChannel = AsynchronousFileChannel.open(sourceFile.toPath());
TransferManager.uploadFileToBlockBlob(fileChannel, blob, 8 * 1024 * 1024, null, null).subscribe(response -> System.out.println("Completed upload request. : " + response.response().statusCode()));
}
}
如您所见，这主要是示例代码，该代码可在github上获得，而没有交互式菜单。此类在应用程序的开头实例化，当我们需要上传文件时，将调用upload方法。而已。我们不会每次都创建一个新实例，而是在需要时重复使用同一实例。
