artemis配置:

 <auto-delete-queues>true</auto-delete-queues>
      <auto-delete-created-queues>true</auto-delete-created-queues>
      <auto-delete-queues-delay>86400000</auto-delete-queues-delay>
      <auto-delete-queues-message-count>0</auto-delete-queues-message-count>
      <config-delete-queues>FORCE</config-delete-queues>

      <auto-delete-addresses>true</auto-delete-addresses>
      <auto-delete-addresses-delay>86400000</auto-delete-addresses-delay>
      <config-delete-addresses>FORCE</config-delete-addresses>
         </address-setting>

schedulePeriodForDestinationPurge：10000  每十秒检查一次，默认为0，此功能关闭
gcInactiveDestinations： true  删除掉不活动队列，默认为false
inactiveTimoutBeforeGC：30000 不活动30秒后删除，默认为60秒

修改activemq.xml 在<broker>里添加属性schedulerSupport="true" 重启mq

http://activemq.apache.org/delete-inactive-destinations

<broker xmlns="http://activemq.apache.org/schema/core" schedulePeriodForDestinationPurge="10000">
  <destinationPolicy>
     <policyMap>
        <policyEntries>
           <policyEntry queue=">" gcInactiveDestinations="true" inactiveTimoutBeforeGC="30000"/>
        </policyEntries>
     </policyMap>
  </destinationPolicy>
</broker>

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" useJmx="true" 
		dataDirectory="${activemq.data}" schedulePeriodForDestinationPurge="60000">

        <destinationPolicy>
            <policyMap>
              <policyEntries>
                <policyEntry topic=">" >
                  <pendingMessageLimitStrategy>
                    <constantPendingMessageLimitStrategy limit="1000"/>
                  </pendingMessageLimitStrategy>
                </policyEntry>
		<policyEntry queue=">" gcInactiveDestinations="true" inactiveTimeoutBeforeGC="30000"/>
              </policyEntries>
            </policyMap>
        </destinationPolicy>
