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。
 
 
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
* 消息的生产者(发送者)

public class JmsSender {
        public static void main(String[] args) throws JMSException {
                // ConnectionFactory :连接工厂,JMS 用它创建连接
                ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
                                ActiveMQConnection.DEFAULT_USER,
                                ActiveMQConnection.DEFAULT_PASSWORD,
                                "tcp://192.168.14.117:61616");
                //JMS 客户端到JMS Provider 的连接
                Connection connection = connectionFactory.createConnection();
                connection.start();
                // Session: 一个发送或接收消息的线程
                Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
                // Destination :消息的目的地;消息发送给谁.
                // 获取session注意参数值my-queue是Query的名字
                Destination destination = session.createQueue("my-queue");
                // MessageProducer:消息生产者
                MessageProducer producer = session.createProducer(destination);
                //设置不持久化
                producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
                //发送一条消息
                sendMsg(session, producer);
                session.commit();
                connection.close();
        }

        /**
         * 在指定的会话上,通过指定的消息生产者发出一条消息
         *
         * @param session    消息会话
         * @param producer 消息生产者
         */

        public static void sendMsg(Session session, MessageProducer producer) throws JMSException {
                //创建一条文本消息
                TextMessage message = session.createTextMessage("Hello ActiveMQ!");
                //通过消息生产者发出消息
                producer.send(message);
                System.out.println("");
        }
}
 
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
* 消息的消费者(接受者)
*
* @author leizhimin 2009-8-12 11:41:33
*/

public class JmsReceiver {
        public static void main(String[] args) throws JMSException {
                // ConnectionFactory :连接工厂,JMS 用它创建连接
                ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
                                ActiveMQConnection.DEFAULT_USER,
                                ActiveMQConnection.DEFAULT_PASSWORD,
                                "tcp://192.168.14.117:61616");
                //JMS 客户端到JMS Provider 的连接
                Connection connection = connectionFactory.createConnection();
                connection.start();
                // Session: 一个发送或接收消息的线程
                Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
                // Destination :消息的目的地;消息发送给谁.
                // 获取session注意参数值xingbo.xu-queue是一个服务器的queue,须在在ActiveMq的console配置
                Destination destination = session.createQueue("my-queue");
                // 消费者,消息接收者
                MessageConsumer consumer = session.createConsumer(destination);
                while (true) {
                        TextMessage message = (TextMessage) consumer.receive(1000);
                        if (null != message)
                                System.out.println("收到消息:" + message.getText());
                        else
                                break;
                }
                session.close();
                connection.close();
        }
}
 
 
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,
                <!-- 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:
