配置文件如下

xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-2.0.xsd

org.foo.bar
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
