A Step-by-Step Guide Using the Azure Blob Storage Library

In recent years, cloud storage has become an increasingly popular choice for businesses and individuals alike. With its scalability, reliability, and cost-effectiveness, it’s no surprise that Azure Blob Storage is one of the most widely used cloud storage solutions available today.

In this article, we’ll explore how to integrate Azure Blob Storage with a Spring Boot application using the Azure Blob Storage library, instead of the Microsoft Azure Storage Blob SDK. This integration is particularly useful for those who are looking to build applications that require large-scale data storage capabilities.

Getting started with Azure Blob Storage

1. Sign up for an Azure account and create a Blob Storage account. This will give you access to your Blob Storage account, where you can create and manage your storage containers and blobs.
2. Configure your Spring Boot application to connect to your Blob Storage account. This can be done by adding the Azure Blob Starter to your application’s dependencies

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-azure-storage-blob</artifactId>
    <version>2.4.0</version>
</dependency>java

And adding the required configuration properties to your application.properties file

azure.storage.connection-string=your_connection_string

Uploading and retrieving data from Azure Blob Storage

1- Create a Blob Container and a Blob within that container

BlobServiceClient blobServiceClient = new BlobServiceClientBuilder().connectionString("your_connection_string").buildClient();

BlobContainerClient containerClient = blobServiceClient.getBlobContainerClient(“your_container_name”);

containerClient.create();

BlobClient blobClient = containerClient.getBlobClient(“your_blob_name”);

2- Upload a file to the Blob

blobClient.uploadFromFile("local_file_path");

3- Retrieve a file from the Blob

BlobDownloadOptions options = new BlobDownloadOptions();
BlobDownloadResponse response = blobClient.download(options);

try (InputStream in = response.getValue().getData()) {
// process the data
}

Conclusion:

Integrating Azure Blob Storage with a Spring Boot application using the Azure Blob Storage library is a straightforward process that can bring a number of benefits, including scalability, reliability, and cost-effectiveness. Whether you’re building a new application or looking to upgrade an existing one, Azure Blob Storage is definitely worth considering.
