Spring RabbitTemplate - How to create queues automatically upon send

问题

I am using RabbitMQ together with Spring's RabbitTemplate.

When sending messages to queues using the template send methods, I want the queue to automatically be created/declared if it is not already exists.

It is very important since according to our business logic queue names are generated on run-time and I cannot declare them in advance.

Previously we have used JmsTemplate and any call to send or receive automatically created the queue.

Yes, you can use a RabbitAdmin and admin.getQueueProperties() to see if the queue exists and admin.declareQueue(new Queue(...)) to add a queue. You should probably keep track of which one's you've already checked/created in order to avoid the overhead on every send.

You can also add exchanges and bind queues to them with the admin.

You can use a RabbitAdmin to automatically declare the exchange, queue, and binding. Check out this thread for more detail. This forum also bit related to your scenario. I have not tried spring with AMQP though, but I believe this would do it.

/**
 * Required for executing adminstration functions against an AMQP Broker
 */
@Bean
public AmqpAdmin amqpAdmin() {
    return new RabbitAdmin(connectionFactory());
}

Keep coding !
