已主从模式运行（192.168.2.137为主，192.168.2.136为从），还需在客户端上运行如下命令：
java.naming.provider.url=failover:(tcp://192.168.2.137:61616,tcp://192.168.2.136:61616)?
randomize=false                          ＃没有这一行的话，就变成了networks of brokers
initialReconnectDelay=10            ＃这里的单位是毫秒




activemq的目录里有个example，只要简单配置一下build.xml，即可测试activemq的message的consume和query
<project name="Inbox"default="help"basedir=".">

    <property name="class.dir"value="target/classes"/>
    <property name="activemq.home"value=".."/>
<!-- 作为消息consume的使用本地地址，作为消息query的使用consumer的ip地址 -->
    <!-- example program defaults -->
    <property name="url"value="tcp://localhost:61616"/>
