Using virtual hosts with RabbitMQ in Smallrye Reactive Messaging AMQP 1.0

[soframel]

Hello,

Could you tell me if smallrye-reactive-messaging-amqp used in conjunction with RabbitMQ should work when working with queues inside virtual hosts?

Note: I know there is a specific version for rabbitmq in smallrye-reactive-messaging-rabbitmq, but I would like to check if the AMQP 1.0 version of the lib would fit our needs. In addition, since RabbitMQ 4 will support AMQP 1.0 by default, the change would probably have less impacts on our applications if we could start now the with the generic lib.

I have tested with both properties amqp-virtual-host and mp.messaging.incoming.<mychannel>.virtual-host in a Quarkus application, like this:

amqp-virtual-host=myvh
mp.messaging.incoming.myqueue.virtual-host=myvh
mp.messaging.incoming.myqueue.connector=smallrye-amqp
mp.messaging.incoming.myqueue.address=myqueue
mp.messaging.incoming.myqueue.durable=false

But messages in the queue "myqueue" inside virtual host "myvh" are never read by my application. And if I create a queue "myqueue" in the default vhost, messages are read correctly.
In addition, my first tests for message producer / outgoing configs seem to show similar results (I get errors on RabbitMQ of the form "no exchange 'myqueue-exchange' in vhost '/' ", even though I am targetting another vhost).

Am I missing something to configure virtual hosts?
(Note: I have found this issue in Quarkus: #474 but it's closed since a long time).
Thank you.

Hello,

a small update on this, since RabbitMQ 4.0 was released a few days ago and it supports AMQP 1.0 by default:
After upgrading Smallrye reactive messaging to 4.24.0 (through Quarkus 3.14.4), I still have the same problem, at least for the producer (consumer not tested yet): with both properties specifying a virtual host, my connection is still refused by RabbitMQ 4 when connecting with AMQP 1.0.

RabbitMQ log:

rabbit-1     | 2024-09-24 08:44:19.756430+00:00 [warning] <0.1209.0>                                             {symbol,<<"amqp:not-found">>},
rabbit-1     | 2024-09-24 08:44:19.756430+00:00 [warning] <0.1209.0>                                             {utf8,
rabbit-1     | 2024-09-24 08:44:19.756430+00:00 [warning] <0.1209.0>                                              <<"no exchange 'myqueue-exchange' in vhost '/'">>}

Even though my producer should try to connect to a specific vhost "myvhost" (where the exchange does exist).

Producer properties:

amqp-virtual-host=myvhost
...
mp.messaging.outgoing.myqueue-exchange.virtual-host=myvhost
mp.messaging.outgoing.myqueue-exchange.connector=smallrye-amqp
mp.messaging.outgoing.myqueue-exchange.address=/exchanges/myqueue-exchange
mp.messaging.outgoing.myqueue-exchange.use-anonymous-sender=false

is this a limitation or am I doing something wrong?

thank you.
