Compose for RabbitMq coonection issue from IBM cloud app

Question

I have created a compose for RabbitMq instance in IBM cloud and I'm using it through service binding on my config server application. My application.yaml has the below properties defined to connect to the compose for rabbitmq server:

 spring:
 profiles: config-monitor
 cloud:
     bus:
         enabled: true
 rabbitmq:
      addresses: amqps://USERNAME:PASSWORD@portal-ssl12-36.bmix-xxxxxxxxxxxxxxxx.composedb.com:58288/vhost-xxxxxxxxxxxxxxxxxxxxxxxxxx

Also, with the service binding, environment variables were updated with VCAP credentials for RabbitMQ.

Maven dependencies:

 <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-config-monitor</artifactId>
     <version>1.4.3.RELEASE</version>
 </dependency>
 <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
     <version>1.3.4.RELEASE</version>
 </dependency>

The issue is on startup I get connection exceptions for RabbitMq Service:

o.s.amqp.rabbit.core.RabbitAdmin : Failed to declare exchange: Exchange [name=springCloudBus, type=topic, durable=true, autoDelete=false, internal=false, arguments={}], continuing...

I do not have any other special code yet to create exchanges/ queues etc.

Any idea why it should fail with connection issues between an application deployed in ibm-cloud and the rabbitmq service which is also provisioned by ibm-cloud?

Spring boot uses amqp protocol to connect to RabbitMQ while Compose services on IBM Cloud are exposed through a HAProxy as amqps.

On my case I changed the connection URI directly on rabbitConnectionFactory by creating a @Configuration bean:

@Configuration
@EnableRabbit
public class MessagingConfiguration {

    @Bean
    public CachingConnectionFactory rabbitConnectionFactory(RabbitProperties config) throws Exception {

        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.getRabbitConnectionFactory().setUri(RABBITMQ_ADDRESS);

        return connectionFactory;

    }

}

You can also use your VCAP variable on application.yml file and inject on configuration bean using the Spring Boot @Value annotation.
