Unable to use Azurite as an Blob Storage emulator using storage spring boot starter:2.2.0

[zoosm3]

Environment

• Spring boot starter:

  • storage spring boot starter:2.2.0

• OS Type: Windows 10

• Java version:

  • 11

• I'm using Azurite and Azure Storage Emulator for local development

Summary

Unable to use the Blob Storage emulators with this SDK

Reproduce steps

1. Use the latest Azurite or Azure Storage Emulator

2. Configure application.properties based on Azurete's Storage Accounts

azure.storage.account-name=devstoreaccount1
azure.storage.account-key=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
azure.storage.container-name=upload
azure.storage.allow-telemetry=false

3. Upload a file with TransferManager

final BlockBlobURL blockBlobURL = containerURL.createBlockBlobURL(getFullPath());

final AsynchronousFileChannel fileChannel = AsynchronousFileChannel.open(Paths.get(bean.getFullPath()));

TransferManager.uploadFileToBlockBlob(fileChannel, blockBlobURL, 8 * 1024 * 1024, createUploadOptions(getMimeType()))
                    .toCompletable()
                    .doOnComplete(() -> { putLog(); })
                    .doOnError(error -> { putLog(); })
                    .blockingAwait();

Expected Results

A file shoud be successfully uploaded to the Blob storage emulator but failed

because the endpoing is not 'http://devstoreaccount1.blob.core.windows.net/' but http://127.0.0.1:10000/myaccount/according to Enulator's Endpoint & Connection URL

Actual Results

Hi @zoosm3,
Thanks for your feedback, as you said, the SDK doesn't support local emulator yet, because the endpoint is hard-coded in the SDK. You can have a try in Azure as your workaround. We may consider adding this feature in our next release. Very very sorry for the inconvenience.

@neuqlz Hello, thanks for your support. We could upload files with a real Azure Blob Storage. Looking forward to the future update.

Any update on this? Will you support the emulator in the foreseeable future?
Thanks.

I can submit a pull request if no one is available for this.

Nice, this weekend will be fun!
