To Reproduce Simple Spring Boot app with using the library

        <dependency>
            <groupId>com.azure.spring</groupId>
            <artifactId>spring-cloud-azure-starter-jdbc-postgresql</artifactId>
            <version>4.5.0-beta.1</version>
        </dependency>

Followed the guide as defined here https://learn.microsoft.com/en-us/azure/developer/java/spring-framework/configure-spring-data-jpa-with-azure-postgresql?toc=%2Fazure%2Fpostgresql%2Ftoc.json&bc=%2Fazure%2Fbread%2Ftoc.json&tabs=passwordless

also set the following properties

  datasource:
    url: jdbc:postgresql://<myDB>.postgres.database.azure.com:5432/postgres?sslmode=require
    username: <myRole>@<myDB>
    azure:
      passwordless-enabled: true

Code Snippet After the properties, the application fails at the start while trying to create connection pool.

Expected behavior The connection pool should have been setup without any errors.

Setup (please complete the following information):

• OS: Windows
• IDE: IntelliJ
• Library/Libraries: 4.5.0-beta.1
• Java version: 17
• App Server/Environment: Tomcat
• Frameworks: Spring Boot

Additional context The example in the link considers System Managed Identity, but User Managed Identity is not explained on how to use or setup. I have defined the default identity using the following properties but not sure if this is the right way.

spring:
  cloud:
    azure:
      credential:
        managed-identity-enabled: true
        client-id: *clientID
        client-secret: *clientSecret
      profile:
        tenant-id: *tenantID
        cloud-type: azure

Hi,

Thanks and I will check this out and see if I can find the issue. In the meantime, we also deployed a azre spring cloud instance to see if this works there, but running into java version issue. For that I will have to raise another issue at the portal side… 😦
