java - How to configure concurrency to a single queue -

-

i configure number of consumers single queue in jms template. tried implement this: jmstemplate - define concurrency per queue? in activemqqueue stiil shows 1. messanging context:

<bean id="parentcontainer" abstract="true"     class="org.springframework.jms.listener.defaultmessagelistenercontainer">         <property name="connectionfactory" ref="connectionfactory" />     </bean>      <bean id="parentcontainer" abstract="true"     class="org.springframework.jms.listener.defaultmessagelistenercontainer">         <property name="connectionfactory" ref="connectionfactory" />     </bean>      <bean id="playerstatslistener" parent="parentcontainer">         <property name="destination" ref="playerstatsqueue" />         <property name="messagelistener" ref="playerstatsservice" />         <property name="concurrency" value="100" />     </bean>      <!-- listeners -->     <bean id="playerstatsservice" class="com.xxx.service.playerstatsservice" />     <!-- destinations -->         <bean id="playerstatsqueue" class="org.apache.activemq.command.activemqqueue">         <constructor-arg value="playerstatsqueue" />

another related question: there difference between "listener" "messagelistener" property?

in general, can set concurrentconsumers , maxconcurrentconsumers on defaultmessagelistenercontainer. concurrency setting gives convenient range.

but according docs

specify concurrency limits via "lower-upper" string, e.g. "5-10", or simple upper limit string, e.g. "10" (the lower limit 1 in case).

so if concurrency=100, it's still equivalent 1-100, explain why you're seeing 1 consumer.
