I am writing an application that uses STOMP for communication. Server side is written using Spring Boot 2.1.7 and as external broker RabbitMQ 3.7.1 is used. On the client side, I am using StompJS.
When a client subscribes to a user destination, eg. /user/queue/some-queue Spring will map it to /queue/some-queue-{sessionID} and RabbitMQ creates a queue with a corresponding name.
On subscription I added header {'auto-delete': true}, as specified here RabbitMQ Stomp Docs, and that created an auto delete queue in RabbitMQ.
Problem comes when I try sending a message to user as
simpTemplate.convertAndSendToUser('user', '/queue/some-queue', message)
Spring correctly translated the queue name, but RabbitMQ responds with an error
PRECONDITION_FAILED - inequivalent arg 'auto_delete' for queue
What can I do to fix this issue?
I think I found a solution. If I add same same headers, which were defined during subscription, when sending message, it will work correctly.
On example it looks like this:
Map<String, Object> headers = new HashMap<>();
headers.put("auto-delete", "true");
simpMessagingTemplate.convertAndSendToUser("some-user", "/queue/some-queue", "Test payload", headers);
