如何在java中的azure中的父目录下添加子目录?

我正在通过java服务在azure存储帐户中创建目录。

jSON输入是:

{   "accountName" : "name", 
    "accountkey"  : "keyOfAzureAccount",

    "directoryStructure" : "directory1/directory2/directory3/directory4/directory5"
}

我期待的是在azure帐户中创建一对一的目录。就像directory5将在directory4中。 directory4将在directory3中。 directory3将在directory2中,而directory2将在directory1中。

我的java代码如下:

@Override
    public JSONObject createDynamicDirectory(JSONObject jsonInput) throws InvalidKeyException, URISyntaxException {
        CloudFileClient fileClient = null;
        String storageConnectionString = "DefaultEndpointsProtocol=https;AccountName="+jsonInput.get("accountName")+";"+"AccountKey="+jsonInput.get("accountkey");
        System.out.println(storageConnectionString);
        CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString);
        JSONObject jsonOutput = new JSONObject();
        try {
            fileClient = storageAccount.createCloudFileClient();
            String directoryName = jsonInput.get("directoryStructure").toString();

            String[] directoryNameArray = directoryName.split("\\s*/\\s*");
            System.out.println(directoryNameArray.length);

            CloudFileShare share = fileClient
                    .getShareReference(directoryNameArray[0].toLowerCase().replaceAll("[-+.^:,!@#$%&*()_~`]", ""));
            if (share.createIfNotExists()) {
                System.out.println("New share created named as "
                        + directoryName.toLowerCase().replaceAll("[-+.^:,!@#$%&*()_~`]", ""));
            }
            for(int i=0;i<directoryNameArray.length;i++)
            {
                CloudFileDirectory rootDir = share.getRootDirectoryReference();
                CloudFileDirectory parentDirectory = rootDir.getDirectoryReference(directoryNameArray[i]);
                if (parentDirectory.createIfNotExists()) {
                    System.out.println("new directory created named as " + directoryName);
                    jsonOutput.put("status", "successful");
                }
            }

        } catch (Exception e) {
            System.out.println("Exception is " + e);
            jsonOutput.put("status", "unsuccessful");
            jsonOutput.put("exception", e.toString());
        }
        return jsonOutput;
    }
}

此代码根据需要从directory1创建共享。但问题是,在同一份额下,它会创建所有目录1,2,3,4,5。不像所需的一对一目录。

如何实现我的java代码,以便可以根据需要创建目录?

尝试这样的事情(代码在C#中)

        var parentDirectory = share.GetRootDirectoryReference();
        for (var i=1; i< directoryNameArray.Length; i++)
        {
            var directoryToCreate = directoryNameArray[i];
            var directory = parentDirectory.GetDirectoryReference(directoryToCreate);
            directory.CreateIfNotExists();
            Console.WriteLine("Created directory - " + directoryToCreate);
            parentDirectory = directory;
        }

基本上,您从作为根目录的共享开始,当您开始创建子目录时,您将继续更新根目录的引用。
