Spring2.5整合ActiveMQ 5.2（P2P文本消息）

怼烎@ 2022-05-09 03:30 238阅读 0赞

想找个Spring整合ActiveMQ可运行的实例，快速看看效果，可是很失望，网上例子都是抄来抄去，没源码（或者有源码运行不了），真TM没意思，看文档我自己实现个，不能运行你砍我！

不想把例子搞的太复杂，越简单越好！

**项目环境：**

JDK1.5

ActiveMQ5.2

所用的包都是ActiveMQ自带的。引用的包如下图：

运行发送端三次：

成功发送了一条JMS消息  
  
Process finished with exit code 0

然后再运行接收端一次：

收到消息内容为: 发送消息：Hello ActiveMQ Text Message！  
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！  
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！

继续测试发现，接收端接收一条消息后不退出程序，而是继续等待，一旦有消息发送过来，就获取到，然后输出！

发一张图看看：
