Spring和ActiveMQ集成实现队列消息以及PUB/SUB模型
前言:本文是基于Spring和ActiveMQ的一个示例文章,包括了Point-To-Point的异步队列消息和PUB/SUB(发布/订阅)模型,只是做了比较简单的实现,无任何业务方面的东西,作为一个入门教程。
适合对象:希望学习ActiveMQ的朋友,以及利用Spring将ActiveMQ集成到系统中

运行截图:
消息发送采用的是Spring提供的JmsTemplate,采用的是异步操作的方式,将消息发布到队列中,消费者可以随时接受这条消息。
从上图可以看出队列模型和PUB/SUB模型的区别,Queue只能由一个消费者接收,其他Queue中的成员无法接受到被已消费的信息,而Topic则可以,只要是订阅了Topic的消费者,全部可以获取到生产者发布的信息。
如果有不懂的在下面问我。
备注:原文地址http://www.xdemo.org/spring-activemq-pub-sub/
代码我分享到了开源中国上,链接地址:
https://git.oschina.net/jiafuwei0407/Hello
通过maven把它build成一个IDE项目,执行以下命令,打开CMD:
$ cd SpringActiveMQ
$ mvn eclipse:eclipse or mvn idea:idea
我在原作者的基础上增加了本地ActiveMQ的访问,就是不需要启动ActiveMQ服务器,就可以发生消息
下面这段配置 ,增加了自定义消息的配置以及自定义消息的转换器,代码中都有注释。
