activeMQ 与TOMCAT 结合

[i]activeMQ内置在Tomcat(6.0)中：[/i]

[b]activemq.xml[/b]

<beans

      <transportConnector uri="stomp://localhost:61613"/>
    </transportConnectors>

  </broker>

</beans>

[b]web.xml[/b]

 <context-param>
	   <param-name>brokerURI</param-name>
	   <param-value>/WEB-INF/activemq.xml</param-value>
	</context-param>

    <listener>
    <listener-class>org.apache.activemq.web.SpringBrokerContextListener</listener-class>
    </listener>

[b]tomcat的conf的context.xml(添加JNDI resouce)[/b]

<Resource

		auth="Container"
		type="org.apache.activemq.command.ActiveMQQueue"
		factory="org.apache.activemq.jndi.JNDIReferenceFactory"
		physicalName="MY.TEST.FOO.QUEUE"/>

[b]spring 的 applicationContext.xml[/b]

 <!--##START using jndi to get resouce on tomcat server  -->

         <bean id="connectionFactory"

默认在tomcat的bin下生成active-data文件夹，你的队列的数据存放在activemq-data\kr-store\data\data-queue-data-1中
hash-index-queue-data_queue#3a#2f#2fMY.TEST.FOO.QUEUE是你的队列的索引文件。
每次发生消息，可以看到在增长。
