Jean-Baptiste Onofré commented on AMQ-8437:
-------------------------------------------
Are you sure you want to target {{app/events/*}} ? Is it not more
{{app/events/>}} ?
It's described here: https://activemq.apache.org/wildcards
> Destination policy not applied when multiple policies with wildcard exist
> -------------------------------------------------------------------------

> Key: AMQ-8437
> URL: https://issues.apache.org/jira/browse/AMQ-8437
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.16.0, 5.16.3
> Environment: centos 7; activeMQ version 5.16.3
> Reporter: Rohan Chauhan
> Priority: Major
>
> I am setting up deadLetterPolicies for undelivered messages but the
> individualDeadLetterStrategy doesn't get applied if I use a wildcard. I was
> expecting creation of DLQ.app/events/foo to be created, for a queue named
> app/events/foo, and undelivered messages moved into it. Unfortunately the
> individual DLQ is not created and undelivered messages end up in default DLQ
> i.e. ActiveMQ.DLQ.
> {code:java}
> <destinationPolicy>
> <policyMap>
> <policyEntries>
> <!-- Set the following policy on all queues using the '>'
> wildcard -->
> <policyEntry queue=">">
> <!--
> Tell the dead letter strategy not to process expired
> messages
> so that they will just be discarded instead of being
> sent to
> the DLQ, next we add specific policies for each
> queue.
> -->
> <deadLetterStrategy>
> <sharedDeadLetterStrategy processExpired="false" />
> </deadLetterStrategy>
> </policyEntry>
> <policyEntry queue="app/events/*">
> <deadLetterStrategy>
> <!--
> Use the prefix 'DLQ.' for the destination name,
> and make
> the DLQ a queue rather than a topic
> -->
> <individualDeadLetterStrategy queuePrefix="DLQ."
> useQueueForQueueMessages="true"/>
> </deadLetterStrategy>
> </policyEntry>
> </policyEntries>
> </policyMap>
> </destinationPolicy>{code}
>
> The individualDeadLetterStrategy works fine when I don't use wildcard.
