Is there any possibility to read topic from JMS message as a consumer

Summary:

I have created a small Spring Boot application which should consume messages from a Solace instance. In Solace the publisher has maintained a queue which is subscribed to different topics. I, as consumer, am processing the messages provided in the queue. Depending on the original topic leading to a message in this queue I would like to react differently in my business logic. Means I need to somehow extract the topic of the message provided via the solace queue.

I have already have checked JMS header/properties, but I found nothing related to topic.

Anyone any idea or had a similar use case?

A workaround which came to my mind was to directly subscribe to all topics and create for every topic a method to consume and react accordingly, but then we would miss the queue features, or?

Solution

Actually the Destination and JMSDestination headers should contain the topic that the message was published to.

For example, to test this real quick I created a StackOverflowQueue queue with a topic subscription to the this/is/a/topic topic. And upon publishing a message to this/is/a/topic my consumer, which was listening to the queue, got the topic info in the header.

To quickly test I used the JMS sample here: https://github.com/SolaceSamples/solace-samples-jms/blob/master/src/main/java/com/solace/samples/QueueConsumer.java

Awaiting message...

Note that sample code doesn't use Spring Boot, but that shouldn't make a difference.
