[BUG] ServiceBus AutoConfiguration is broken

[yanivnahoum]

When configuring com.azure.spring:spring-cloud-azure-starter-servicebus with connection-details via the consumer, processor, and/or the producer and NOT via the top-level key, auto-configuration fails.

Exception or Stack Trace

To Reproduce
Steps to reproduce the behavior:

spring:
  cloud:
    azure:
      servicebus:
        processor:
          connection-string: Endpoint=dummy;SharedAccessKeyName=dummy;SharedAccessKey=dummy
          entity-name: some-queue
          entity-type: queue
        producer:
          connection-string: Endpoint=dummy;SharedAccessKeyName=dummy;SharedAccessKey=dummy
          entity-name: some-other-queue
          entity-type: queue

RCA
In the previous versions, com.azure.spring.cloud.autoconfigure.implementation.servicebus.AzureServiceBusAutoConfiguration defined the following bean if spring.cloud.azure.servicebus.enabled is true or missing completely.

    @Bean
    @ConfigurationProperties(AzureServiceBusProperties.PREFIX)
    AzureServiceBusProperties azureServiceBusProperties() {
        return loadProperties(getAzureGlobalProperties(), new AzureServiceBusProperties());
    }

In the new versions (5.25.0 and 7.1.0), AzureServiceBusAutoConfiguration imports AzureServiceBusPropertiesConfiguration which in turn imports the newly introduced com.azure.spring.cloud.autoconfigure.implementation.servicebus.properties.ConfigurationWithoutConnectionDetailsBean that defines this bean:

    @Bean
    @ConditionalOnMissingBean
    @ConfigurationProperties(AzureServiceBusProperties.PREFIX)
    AzureServiceBusProperties azureServiceBusProperties() {
        return AzureGlobalPropertiesUtils.loadProperties(azureGlobalProperties, new AzureServiceBusProperties());
    }

but ConfigurationWithoutConnectionDetailsBean is considered only if:

@ConditionalOnAnyProperty(prefix = "spring.cloud.azure.servicebus", name = {"connection-string", "namespace"})

in the use case above, only spring.cloud.azure.servicebus.processor.connection-string and spring.cloud.azure.servicebus.producer.connection-string are set, so AzureServiceBusProperties is not created.

Workaround
Replace the consumer or processor connection-string (i.e. spring.cloud.azure.servicebus.processor.connection-string) with the top level one (i.e. spring.cloud.azure.servicebus.connection-string):

spring:
  cloud:
    azure:
      servicebus:
        connection-string: Endpoint=dummy;SharedAccessKeyName=dummy;SharedAccessKey=dummy
        processor:          
          entity-name: some-queue
          entity-type: queue
        producer:
          connection-string: Endpoint=dummy;SharedAccessKeyName=dummy;SharedAccessKey=dummy
          entity-name: some-other-queue
          entity-type: queue
