ActiveMQ之Topic 例子

1：http://activemq.apache.org 下载最新版

2：直接解压至任意目录

3:、启动 ActiveMQ服务器 直接运行 bin\activemq.bat 

4：跑个小例子：

import javax.jms.Connection;
import javax.jms.DeliveryMode;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.jms.Topic;

import org.apache.activemq.ActiveMQConnectionFactory;


public class TopicPublisher {
	 public static void main(String[] args) throws JMSException {
		         ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
		         Connection connection = factory.createConnection();
		         connection.start();
		         Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		         Topic topic = session.createTopic("myTopic.messages");
		         MessageProducer producer = session.createProducer(topic);
		         producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
		         for(int i =0;i<10;i++){
		             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();
		    }

}

 

import javax.jms.Connection;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.jms.Topic;

import org.apache.activemq.ActiveMQConnectionFactory;


public class TopicSubscriber {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
		        try {
					Connection connection = factory.createConnection();
					connection.start();
					Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
					Topic topic = session.createTopic("myTopic.messages");
					MessageConsumer consumer = session.createConsumer(topic);
					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();
					        }
					    }
					});
				} catch (JMSException e) {
					e.printStackTrace();
				}
	}

}
