The Basic, Standard plans entered a retirement period on March 17, 2025. For more information, see the Azure Spring Apps retirement announcement.

The Standard consumption and dedicated plan entered a retirement period on September 30, 2024, with a complete shutdown by the end of March 2025.

With Azure Spring Apps, you can bind select Azure services to your applications automatically, instead of having to configure your Spring Boot application manually. This article shows you how to bind your application to your Azure Database for PostgreSQL instance.

In this article, we include two authentication methods: Microsoft Entra authentication and PostgreSQL authentication. The Passwordless tab shows the Microsoft Entra authentication and the Password tab shows the PostgreSQL authentication.

Microsoft Entra authentication is a mechanism for connecting to Azure Database for PostgreSQL using identities defined in Microsoft Entra ID. With Microsoft Entra authentication, you can manage database user identities and other Microsoft services in a central location, which simplifies permission management.

PostgreSQL authentication uses accounts stored in PostgreSQL. If you choose to use passwords as credentials for the accounts, these credentials are stored in the user table. Because these passwords are stored in PostgreSQL, you need to manage the rotation of the passwords by yourself.

Prerequisites

Prepare your project

Use the following steps to prepare your project.

  1. In your project's pom.xml file, add the following dependency:

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-starter-jdbc-postgresql</artifactId>
</dependency>

  2. In the application.properties file, remove any spring.datasource.* properties.

  3. Update the current app by running az spring app deploy, or create a new deployment for this change by running az spring app deployment create.
