1、环境:
Windows XP
apache-activemq-5.2.0-bin.zip
2、安装
解压缩到apache-activemq-5.2.0-bin.zip到一个目录,比如C:\apache-activemq-5.2.0
3、配置
配置就在C:\apache-activemq-5.2.0\conf目录下三个文件
activemq.xml
credentials.properties
log4j.properties
4、启动ActiveMQ
运行C:\apache-activemq-5.2.0\bin\activemq.bat
5、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 netstat -an|find "61616"
C:\Documents and Settings\Administrator>netstat -an|find "61616"
TCP 0.0.0.0:61616 0.0.0.0:0 LISTENING
6、监控
ActiveMQ5.0版本默认启动时,启动了内置的jetty服务器,提供一个demo应用和用于监控ActiveMQ的admin应用。
admin:http://127.0.0.1:8161/admin/
demo:http://127.0.0.1:8161/demo/
下面是ActiveMQ5.2的一个最简单例子!
环境还是apache-activemq-5.2.0-bin.zip,需要注意的是,开发时候,要将apache-activemq- 5.2.0-bin.zip解压缩后里面的activemq-all-5.2.0.jar包加入到classpath下面,这个包包含了所有jms接口 api的实现。

启动ActiveMQ,然后开始执行:
先运行发送者,连续运行了三次,最后一次控制台输出:
Process finished with exit code 0
后运行接受者,输出结果:
收到消息Hello ActiveMQ!
收到消息Hello ActiveMQ!
收到消息Hello ActiveMQ!
Process finished with exit code 0
注意:
其中的端口61616是ActiveMQ默认的配置,在activemq.xml中,
-
-
<transportConnectors>
-
<transportConnector name="openwire" uri="tcp://localhost:61616" discoveryUri="multicast://default"/>
-
<transportConnector name="ssl" uri="ssl://localhost:61617"/>
-
<transportConnector name="stomp" uri="stomp://localhost:61613"/>
-
<transportConnector name="xmpp" uri="xmpp://localhost:61222"/>
-
</transportConnectors>
<!-- The transport connectors ActiveMQ will listen to --> <transportConnectors> <transportConnector name="openwire" uri="tcp://localhost:61616" discoveryUri="multicast://default"/> <transportConnector name="ssl" uri="ssl://localhost:61617"/> <transportConnector name="stomp" uri="stomp://localhost:61613"/> <transportConnector name="xmpp" uri="xmpp://localhost:61222"/> </transportConnectors>
,建议不要改动,都用这个端口多好,就像ftp都用21端口,也没错。
这是官方的HelloWorld例子,不过看着不顺眼:
