Azure StorageException：发生未知失败：连接超时：connect

-3

我正在创建小型JAVA程序以访问Azure blob存储，如下所示。Azure StorageException：发生未知失败：连接超时：connect

不过，我可以能够使用存储资源管理器（具有相同的连接字符串）

访问同一存储，但我无法访问使用Java代码相同的日食。

CloudStorageAccount account = CloudStorageAccount.parse(storageConnectionString);  

CloudBlobClient serviceClient = account.createCloudBlobClient(); 

// Container name must be lower case. 
CloudBlobContainer container = serviceClient.getContainerReference("testeventdata"); 

// Download the JSON file. 
CloudBlockBlob blob = container.getBlockBlobReference("TEST2.json"); 

// Download file 
File sourceFile = new File("d:\\LHWMSGDownLoad.json"); 

File destinationFile = new File(sourceFile.getParentFile(), 
          "TESTDownLoad.json"); 

// **** On following line I am getting ERROR ***** 
// *********************************************** 
blob.downloadToFile(destinationFile.getAbsolutePath());

错误说明：

您是否试图在存储模拟器或云存储帐户中使用代码？ –

正在使用我的云存储帐户subscrption –

按我的经验，我认为这不是你的代码错误很明显，但它可能会通过一些配置在您的本地机器或网络环境造成的可能性很大，如防火墙阻止来自Java的请求。请检查并确保这些可能的系统配置或软件是否阻止它。
