Spring boot unable to create multiple rabbit connection factories - spring

Question

I am trying to connect to and consume from two different clusters of rabbitmq using a spring boot app via xml. It works well when a single rabbit:connection-factory bean is created in the application context. However, when the second one is added, it fails to start the application with the error "Parameter 1 of method rabbitListenerContainerFactory in org.springframework.boot.autoconfigure.amqp.RabbitAnnotationDrivenConfiguration required a single bean, but 2 were found:". How do I go about creating different factories per cluster? Please suggest an alternative way of doing this, if it's not the right approach?
Here is the xml snippet:
<rabbit:connection-factory id="firstConnectionFactory" connection-factory="firstSpringConnectionFactory" />
<rabbit:connection-factory id="secondConnectionFactory" connection-factory="secondSpringConnectionFactory"/>
<bean id="firstSpringConnectionFactory"
class="org.springframework.amqp.rabbit.connection.RabbitConnectionFactoryBean">
<property name="useSSL" value="${rabbitmq.ssl.enabled}" />
<property name="host" value="${rabbitmq.first.host}"/>
<property name="virtualHost" value="${rabbitmq.vhost}"/>
<property name="port" value="${rabbitmq.cluster.port}"/>
<property name="username" value="${rabbitmq.user}"/>
<property name="password" value="${rabbitmq.first.password}"/>
</bean>
<bean id="secondSpringConnectionFactory"
class="org.springframework.amqp.rabbit.connection.RabbitConnectionFactoryBean">
<property name="useSSL" value="${rabbitmq.ssl.enabled}" />
<property name="host" value="${rabbitmq.second.host}"/>
<property name="virtualHost" value="${rabbitmq.vhost}"/>
<property name="port" value="${rabbitmq.cluster.port}"/>
<property name="username" value="${rabbitmq.user}"/>
<property name="password" value="${rabbitmq.second.password}"/>
</bean>
And the listener container code:
ConnectionFactory cf = rabbitConnectionFactory;//One of the connnection factories will be injected here from app context
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
container.setConnectionFactory(cf);
container.setConcurrentConsumers(count);
container.addQueueNames(queueName);
container.setMessageListener(listener);
container.start();

Since you don't rely on the Spring Boot here and don't use Spring AMQP annotation support I suggest you to exclude RabbitAnnotationDrivenConfiguration from auto-configuration:
#EnableAutoConfiguration(exclude={RabbitAnnotationDrivenConfiguration.class})
spring.autoconfigure.exclude = org.springframework.boot.autoconfigure.amqp.RabbitAnnotationDrivenConfiguration
If you still need #RabbitListener somewhere in other place of your project, you only have a choice to build all the #EnableRabbit infrastructure manually.
