Quickstart: Deploy your first Spring Batch application to Azure Spring Apps

Note

The first 50 vCPU hours and 100 GB hours of memory are free each month. For more information, see Price Reduction - Azure Spring Apps does more, costs less! on the Apps on Azure Blog.

Note

Azure Spring Apps is the new name for the Azure Spring Cloud service. Although the service has a new name, you'll see the old name in some places for a while as we work to update assets such as screenshots, videos, and diagrams.

This quickstart shows how to deploy a Spring Batch ephemeral application to Azure Spring Apps. The sample project is derived from the Spring Batch sample Football Job. It's a statistics loading job. In the original sample, a unit test triggers the job. In the adapted sample, the main method of FootballJobApplication initiates the job.

This article applies to: ❌ Basic/Standard ✔️ Enterprise

The following diagram shows the architecture of the system:

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.
