Does Apache Camel supports activemq wildcard consumers?

Question

I need a way to consume messages from multiple activemq jms queues.

As per activemq documentation, it supports wildcard consumers

I am using camel as a messaging bus.Is it possible to look at below named queues

aaa.processQueue
bbb.processQueue
ccc.processQueue

By configuring camel route to look at activemq:*.processQueue endpoint?

Also let me know, if there is more cleaner alternative for this.

Answer 1

Yes. It should be doable as Camel is using the OpenWire/JMS client.

Your options are:

1. from("activemq:*.processQueue")
2. from("activemq:aaa.processQueue,bbb.processQueue,ccc.processQueue")

3. Multiple routes with a sub route for logic:

   from("activemq:aaa.processQueue").to("direct:doProcess");
   from("activemq:bbb.processQueue").to("direct:doProcess");
   from("activemq:ccc.processQueue").to("direct:doProcess");
   
   from("direct:doProcess").whatever..
   

   This way, you can easily turn on/off routes as well as assigning more consumers to one, given you need to have more priority on aaa.processQueue messages than the rest.
