spring+activemq实战之配置监听多队列实现不同队列消息消费

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
