spring+activemq实战之配置监听多队列实现不同队列消息消费

摘选：https://my.oschina.net/u/3613230/blog/1457227

摘要: 最近在项目开发中，需要用到activemq，用的时候，发现在同一个项目中point-to-point模式中，配置多个队列，消息生成者只能往一个队列中发消息或者往多个队列发送相同消息，并且监听器只能监听一个队列，这样配置多个队列也没有意义，作者想要实现的是：配置多个队列，并且生产者可以往多个队列中发送不同的消息，监听器消费时，可以判断根据不同的队列进行相应的业务处理，网上搜了一个，发现都是单个队列和监听，研究了一下，发现是可以实现的，废话不多说，直接上代码：

-启动项目访问main,进行消息发送：

后台打印往不同队列发送的消息和监听到不同队列中的消息：

队列queue1发送消费了14条消息，queue2发送消费了10条消息：

到此想要的功能需求已实现
