ActiveMQ开发实例3

MessagePublisher类

package activemq.yang; import java.util.Date;import javax.jms.Connection;import javax.jms.DeliveryMode;import javax.jms.JMSException;import javax.jms.MessageProducer;import javax.jms.Session;import javax.jms.Topic;import org.apache.activemq.ActiveMQConnectionFactory; public class MessagePublisher implements Runnable {    private String url;    private String user;    private String password;    private String topicName;     public MessagePublisher(String topicName, String url, String user,            String password) {        this.url = url;        this.user = user;        this.password = password;        this.topicName = topicName;    }     @Override    public void run() {                try {        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, password, url);              Connection connection = connectionFactory.createConnection();            connection.start();            System.out.println(Thread.currentThread().getName() + "开启");            //创建Topic            //Topic topic = new ActiveMQTopic(this.topicName);            Session session  = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);            Topic topic = session.createTopic(this.topicName);            MessageProducer sendPublisher = session.createProducer(topic);            sendPublisher.setDeliveryMode(DeliveryMode.NON_PERSISTENT);                        for(int i = 0; i < 5; i++){            String text = new Date() + " 现在发送是第" + (i+1) + "条消息";                sendPublisher.send(session.createTextMessage(text));                System.out.println("send message :" + text);//                Thread.sleep(1000);            }                        sendPublisher.close();            session.close();            connection.close();             //            System.out.println("发布消息线程结束******************************");        } catch (JMSException e) {            e.printStackTrace();        }    }     public String getUrl() {        return url;    }     public void setUrl(String url) {        this.url = url;    }     public String getUser() {        return user;    }     public void setUser(String user) {        this.user = user;    }     public String getPassword() {        return password;    }     public void setPassword(String password) {        this.password = password;    }     public String getTopic() {        return topicName;    } }

MessageSubscriber类

package activemq.yang;import javax.jms.Connection;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.Topic; import org.apache.activemq.ActiveMQConnectionFactory; public class MessageSubscriber implements Runnable {    private String url;    private String user;    private String password;    private String topicName;     public MessageSubscriber(String topicName, String url, String user,            String password) {        this.url = url;        this.user = user;        this.password = password;        this.topicName = topicName;    }     @Override    public void run() {        try {                ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, password, url);            Connection connection = connectionFactory.createConnection();            Session  session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);             // 创建Topic            Topic topic = session.createTopic(this.topicName);            MessageConsumer subscriber = session.createConsumer(topic);            subscriber.setMessageListener(new TextListener());            connection.start();            System.out.println(Thread.currentThread().getName() + "开启");                                    //            subscriber.close();//            session.close();//            connection.close();      }        catch (JMSException e) {            e.printStackTrace();        }             }     public String getUrl() {        return url;    }     public void setUrl(String url) {        this.url = url;    }     public String getUser() {        return user;    }     public void setUser(String user) {        this.user = user;    }     public String getPassword() {        return password;    }     public void setPassword(String password) {        this.password = password;    }     public String getTopic() {        return topicName;    }}

TextListener类，用来监听

package activemq.yang;import javax.jms.*;/** * Text消息监听 *  * @author XXXX<br> *  */public class TextListener implements MessageListener {     /**     * Casts the message to a TextMessage and displays its text.     *      * @param message     *            the incoming message     */    public void onMessage(Message message) {        TextMessage msg = null;         try {            if (message instanceof TextMessage) {                msg = (TextMessage) message;                System.out.println(Thread.currentThread().getName() +"Recevie message: " + msg.getText());            } else {                System.out.println("Message of wrong type: "                        + message.getClass().getName());            }        } catch (JMSException e) {            System.out.println("JMSException in onMessage(): " + e.toString());        } catch (Throwable t) {            System.out.println("Exception in onMessage():" + t.getMessage());        }            }}

测试类MyActiveMQDemo

package activemq.yang;import javax.jms.JMSException;public class MyActiveMQDemo {    public static void main(String[] args) throws InterruptedException, JMSException {        String url = "tcp://localhost:61616";        String user = null;        String password = null;        String topic = "TestTopic";            new Thread(new MessagePublisher(topic,url,user,password), "Publish").start();          new Thread(new MessageSubscriber(topic,url,user,password), "Name-Subscriber1").start();        new Thread(new MessageSubscriber(topic,url,user,password), "Name-Subscriber2").start();//        new Thread(new MessageSubscriber(topic,url,user,password), "Name-Subscriber3").start();//        new Thread(new MessageSubscriber(topic,url,user,password), "Name-Subscriber4").start();//        new Thread(new MessageSubscriber(topic,url,user,password), "Name-Subscriber5").start();    }}

执行程序，结果如下：
