ActionMQ 是开源的JMS实现
1.下载ActiveMQ
去官方网站下载:http://activemq.apache.org/
2.运行ActiveMQ
解压缩apache-activemq-5.5.1-bin.zip,然后双击apache-activemq-5.8.0\bin\activemq.bat运行ActiveMQ程序。
启动ActiveMQ以后,登陆:http://localhost:8161/admin/,创建一个Queue,命名为FirstQueue。如下图
目录结构如下:
运行在网页中,它会让你登录用户方可进入,默认的用户名和密码是admin,
3 . 测试
ActiveMQ默认使用的TCP连接端口是61616,通过查看该端口的信息可以测试ActiveMQ是否成功启动
window环境运行 netstat -an|find "61616"
Class源代码中可以看到
4.创建Eclipse JAVA项目并运行
创建project:ActiveMQ-5.8,并导入apache-activemq-5.8.0\lib目录下需要用到的jar文件,项目结构如下图所示:
若找不到相应的包,使用以下连接下载也行 http://repo1.maven.org/maven2/org/apache/activemq/activemq-rar/

4.注意事项
先启动apache-activemq-5.8.0\bin\activemq.bat运行ActiveMQ程序。在运行main方法 ,否则回报连接失败的错误,如下

5.测试过程
1、先运行Sender,输出以下信息,若先运行Receiver则无输出
发送消息:ActiveMq 发送的消息1
发送消息:ActiveMq 发送的消息2
发送消息:ActiveMq 发送的消息3
发送消息:ActiveMq 发送的消息4
发送消息:ActiveMq 发送的消息5
2、运行Receiver
收到消息ActiveMq 发送的消息1
收到消息ActiveMq 发送的消息2
收到消息ActiveMq 发送的消息3
收到消息ActiveMq 发送的消息4
收到消息ActiveMq 发送的消息5
