Linux下搭建activeMQ
http://blog.csdn.net/gongqingkui/article/details/8928208

搭建

下载ActiveMQ
解压安装包*.tar.gz
进入到bin目录下执行，./activemq start命令，也可以通过./activemq console 命令启动服务，并且输出日志在控制台上。
启动成功，访问URL

如图
这里写图片描述

创建一个queue name
这里写图片描述

到此，我们已经成功创建了一个消息队列。

下面我们通过程序，生产和消费

点对点事例

java代码如下：

分别运行main方法，奇迹就会发生^_^~~~
