[BUG] Circular references about restTemplateBuilder

See original GitHub issue

Describe the bug A Spring Boot 2.7.4 application having dependencies on both spring-boot-starter-data-rest and spring-cloud-azure-starter-active-directory 4.4.0 fails to start due to circular references. Using spring-cloud-azure-starter-active-directory 4.3.0 works fine.

Exception or Stack Trace

***************************
APPLICATION FAILED TO START

Description:

The dependencies of some of the beans in the application context form a cycle:

   com.azure.spring.cloud.autoconfigure.aad.AadAuthenticationFilterAutoConfiguration
┌─────┐
|  restTemplateBuilder defined in class path resource [org/springframework/boot/autoconfigure/web/client/RestTemplateAutoConfiguration.class]
↑     ↓

Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

To Reproduce Create a new Spring Boot project at https://start.spring.io/ and select the following dependencies:

Rest Repositories
Azure Active Directory
Spring Security
OAuth2 Client

Then enable AAD in the application.yaml file:

spring:
  cloud:
    azure:
      active-directory:
        enabled: true
        credential:
          client-id: whatever
          client-secret: whatever
        profile:
          tenant-id: whatever
        user-group:
          allowed-group-names: whatever

Code Snippet N/A

Expected behavior The Spring Boot application starts (and immediately terminates because it’s not a web application) without error.

Screenshots N/A

Setup (please complete the following information):

OS: Windows
IDE: IntelliJ
Library/Libraries:

org.springframework.boot:spring-boot-starter-data-rest:2.7.4
org.springframework.boot:spring-boot-starter-oauth2-client:2.7.4
org.springframework.boot:spring-boot-starter-security:2.7.4
com.azure.spring:spring-cloud-azure-starter-active-directory:4.4.0

Java version: 11
App Server/Environment: N/A
Frameworks: Spring Boot 2.7.4

Additional context This could be related to https://github.com/Azure/azure-sdk-for-java/pull/31048 Downgrading to com.azure.spring:spring-cloud-azure-starter-active-directory:4.3.0 solves the problem. Removing the org.springframework.boot:spring-boot-starter-data-rest dependency also “solves” the problem.
