Spring Boot App for operation on Azure Blob Storage

Azure blob storage code sample

Key concepts

This project is an example for communicating with the Azure Blob storage using the Spring Boot.

Prerequisites

• An Azure subscription
• A Java Development Kit (JDK), version >= 1.8.
• Gradle

Getting started

Configuration

The access of the Azure Blob Storage is based on the connection string of the storage account. We can access the connection string details under the Access Keys section. Refer the screenshot below.

Next thing to grab is container name. Under the storage account there is a tab sections which lists all the containers for the storage account. Refer the image to know it.

Now we can set this as part of the application.yml. Go to src/main/resources for the file.

azure:
  storage:
    connection-string: ${AZURE_STORAGE_CONNECTION_STRING}
    container-name: ${AZURE_STORAGE_CONTAINER_NAME}

Or we pass it as spring boot env arguments.

Build with Gradle

gradlew clean build

Run with Gradle

If AZURE_STORAGE_CONTAINER_NAME and AZURE_STORAGE_CONNECTION_STRING updated on the application.yml then we can start the server by

gradlew bootRun

OR this way if we want to pass it as env config.

set AZURE_STORAGE_CONTAINER_NAME=<container name> & set AZURE_STORAGE_CONNECTION_STRING=<connection_string> & gradlew bootRun
