Apache ActiveMQ是Apache软件基金会所研发的开放源码消息中间件；由于ActiveMQ是一个纯Java程式，因此只需要操作系统支援Java虚拟机，ActiveMQ便可执行。
支持Java消息服务 (JMS) 1.1 版本
Spring Framework
集群 (Clustering)
支持的编程语言包括：C、C++、C#、Delphi、Erlang、Adobe Flash、Haskell、Java、java script、Perl、PHP、Pike、Python和Ruby [1]
协议支持包括：OpenWire、REST、STOMP、WS-Notification、XMPP以及AMQP
好，我们先写个demo来试试 ActiveMQ的效果.
解压后，在x:/apache-activemq-5.8.0-bin/bin 目录下执行 activemq.bat即可启动 ActiveMQ，
由于ActiveMQ内置了Jetty web服务器，当ActiveMQ启动成功后，可以通过：http://localhost:8161/admin/访问ActiveMQ的控制台，默认的用户名和密码是：admin。
至此ActiveMQ 服务已经启动了，接下来我们先将x:/apache-activemq-5.8.0-bin/activemq-all-5.8.0.jar拷贝到你的classpath目录下，利用Java写个demo来尝试一下这个消息中间件。
JmsSender：

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://127.0.0.1:61616");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("Test.foo");
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
for(int i=0; i<100; i++) {
int id = i+1;
ObjectMessage message = session.createObjectMessage();
message.setObject(new User(id, "张三"+id, "123456"));
producer.send(message);

session.commit();
