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.
