Quickstart: Deploy an event-driven application to Azure Spring Apps
Grein
Note
The Basic, Standard, and Enterprise plans will be deprecated starting from mid-March, 2025, with a 3 year retirement period. We recommend transitioning to Azure Container Apps. For more information, see the Azure Spring Apps retirement announcement.
This article applies to: ✔️ Standard consumption and dedicated (Preview) ✔️ Basic/Standard ✔️ Enterprise
This article explains how to deploy a Spring Boot event-driven application to Azure Spring Apps.
The sample project is an event-driven application that subscribes to a Service Bus queue named lower-case, and then handles the message and sends another message to another queue named upper-case. To make the app simple, message processing just converts the message to uppercase. The following diagram depicts this process:
This article provides the following options for deploying to Azure Spring Apps:
The Azure portal option is the easiest and the fastest way to create resources and deploy applications with a single click. This option is suitable for Spring developers who want to quickly deploy applications to Azure cloud services.
The Azure portal + Maven plugin option is a more conventional way to create resources and deploy applications step by step. This option is suitable for Spring developers using Azure cloud services for the first time.
The Azure Developer CLI option is a more efficient way to automatically create resources and deploy applications through simple commands. The Azure Developer CLI uses a template to provision the Azure resources needed and to deploy the application code. This option is suitable for Spring developers who are familiar with Azure cloud services.

The Azure portal + Maven plugin option is a more conventional way to create resources and deploy applications step by step. This option is suitable for Spring developers using Azure cloud services for the first time.
The Azure CLI option uses a powerful command line tool to manage Azure resources. This option is suitable for Spring developers who are familiar with Azure cloud services.
The Deploy to Azure button in the next section launches an Azure portal experience that downloads a JAR package from the ASA-Samples-Web-Application releases page on GitHub. No local preparation steps are needed.
Use the following steps to prepare the sample locally:
The sample project is ready on GitHub. Clone the sample project by using the following command:
Build the sample project by using the following commands:
cd ASA-Samples-Event-Driven-Application
./mvnw clean package
Use the following steps to prepare the sample locally. These steps use AZD to initialize the event-driven application from the Azure Developer CLI templates.
Open a terminal, create a new, empty folder, then navigate to it.
Use the following command to initialize the project:
The following list describes the command interactions:
Enter a new environment name: Provide an environment name, which is used as a suffix for the resource group that is created to hold all Azure resources. This name should be unique within your Azure subscription.
The console outputs messages similar to the following example:
Initializing a new project (azd init)
(✓) Done: Initialized git repository
(✓) Done: Downloading template code to: <your-local-path>
Enter a new environment name: <your-env-name>
SUCCESS: New project initialized!
You can view the template code in your directory: <your-local-path>
