ActiveMQ实战之 Queue点对点消息

对于此类消息，其实就是指使用JMS中的发P2P（点对点）消息模型的消息，下面是一个简单的例子
消息发送者

package com.googlecode.garbagecan.jmsstudy.activemq.queue; import org.apache.activemq.ActiveMQConnection; import org.apache.activemq.ActiveMQConnectionFactory; import javax.jms.*; public class Sender { public static void main(String[] args) throws JMSException { ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616"); Connection connection = connectionFactory.createConnection(); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); Destination destination = session.createQueue("myQueue"); MessageProducer producer = session.createProducer(destination); producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); while(true) { TextMessage message = session.createTextMessage(); message.setText("message_" + System.currentTimeMillis()); producer.send(message); System.out.println("Sent message: " + message.getText()); try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } // session.close(); // connection.stop(); // connection.close(); } }

消息接收者

package com.googlecode.garbagecan.jmsstudy.activemq.queue; import org.apache.activemq.ActiveMQConnection; import org.apache.activemq.ActiveMQConnectionFactory; import javax.jms.*; public class Receiver { public static void main(String[] args) throws JMSException { ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616"); Connection connection = connectionFactory.createConnection(); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); Destination destination = session.createQueue("myQueue"); MessageConsumer consumer = session.createConsumer(destination); consumer.setMessageListener(new MessageListener() { public void onMessage(Message message) { TextMessage tm = (TextMessage) message; try { System.out.println("Received message: " + tm.getText()); } catch (JMSException e) { e.printStackTrace(); } } }); // session.close(); // connection.stop(); // connection.close(); } }

分别运行两个类，就可以看到Sender发布的消息，Receiver都可以接受到。
