[BUG] Azure App Config not Working in Spring boot 4.x / spring framework 7.x beta

[kazi-uddin]

Describe the bug
We are currently testing the beta version of v7 and running into issues when starting the application.
We are using azure app config. But it's unable to create the AppConfigurationRefresh bean due to missing dependencies. It says Factory method 'appConfigurationRefresh' threw exception with message: com.azure.spring.cloud.appconfiguration.config.implementation.AppConfigurationReplicaClientFactory has not been registered

Exception or Stack Trace

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'appConfigurationRefresh' defined in class path resource [com/azure/spring/cloud/appconfiguration/config/AppConfigurationWatchAutoConfiguration.class]: Failed to instantiate [com.azure.spring.cloud.appconfiguration.config.AppConfigurationRefresh]: Factory method 'appConfigurationRefresh' threw exception with message: com.azure.spring.cloud.appconfiguration.config.implementation.AppConfigurationReplicaClientFactory has not been registered

To Reproduce
Steps to reproduce the behavior:

Used this example from here:
https://github.com/Azure-Samples/azure-spring-boot-samples/tree/spring-boot-4.x/appconfiguration/spring-cloud-azure-feature-management-web/spring-cloud-azure-feature-management-web-sample

Added app configuration web dependency in pom

<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-appconfiguration-config-web</artifactId>
</dependency>

Added in application.yml

spring:
  thymeleaf:
    cache: false
  cloud:
    azure:
      appconfiguration:
        enabled: true
        stores:
          - connection-string: Endpoint=https://**************************
            feature-flags:
              enabled: true
        credential:
          managed-identity-enabled: false

Code Snippet
See above

Expected behavior
The application should connect to azure app config server and fetch app configuration including feature flags.

Screenshots

Setup (please complete the following information):

• OS: Ubintu 24.04
• IDE: IntelliJ
