ActiveMQ的queue和topic两种模式的示例演示

以前从网上收集到的代码，很实用，可惜忘了地址了。在这里感谢一下原作者的辛勤劳动，改日发现链接的话一定补上。

queue模式：

ConsumerTest.java

package queue;import javax.jms.JMSException;public class ConsumerTest implements Runnable {static Thread t1 = null;/** * @param args * @throws InterruptedException * @throws InterruptedException * @throws JMSException * @throws InterruptedException */public static void main(String[] args) throws InterruptedException {t1 = new Thread(new ConsumerTest());t1.start();while (true) {System.out.println(t1.isAlive());if (!t1.isAlive()) {t1 = new Thread(new ConsumerTest());t1.start();System.out.println("重新启动");}Thread.sleep(5000);}// 延时500毫秒之后停止接受消息// Thread.sleep(500);// consumer.close();}public void run() {try {ConsumerTool consumer = new ConsumerTool();consumer.consumeMessage();while (ConsumerTool.isconnection) {}} catch (Exception e) {}}}

ConsumerTool.java

package queue;import javax.jms.Connection;import javax.jms.Destination;import javax.jms.ExceptionListener;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.MessageListener;import javax.jms.Message;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;public class ConsumerTool implements MessageListener, ExceptionListener {private String user = ActiveMQConnection.DEFAULT_USER;private String password = ActiveMQConnection.DEFAULT_PASSWORD;private String url = ActiveMQConnection.DEFAULT_BROKER_URL;private String subject = "myqueue";private Destination destination = null;private Connection connection = null;private Session session = null;private MessageConsumer consumer = null;private ActiveMQConnectionFactory connectionFactory = null;public static Boolean isconnection = false;// 初始化private void initialize() throws JMSException {connectionFactory = new ActiveMQConnectionFactory(user, password, url);connection = connectionFactory.createConnection();session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);destination = session.createQueue(subject);consumer = session.createConsumer(destination);}// 消费消息public void consumeMessage() throws JMSException {initialize();connection.start();consumer.setMessageListener(this);connection.setExceptionListener(this);System.out.println("Consumer:->Begin listening...");isconnection = true;// 开始监听// Message message = consumer.receive();}// 关闭连接public void close() throws JMSException {System.out.println("Consumer:->Closing connection");if (consumer != null)consumer.close();if (session != null)session.close();if (connection != null)connection.close();}// 消息处理函数public void onMessage(Message message) {try {if (message instanceof TextMessage) {TextMessage txtMsg = (TextMessage) message;String msg = txtMsg.getText();System.out.println("Consumer:->Received: " + msg);} else {System.out.println("Consumer:->Received: " + message);}} catch (JMSException e) {e.printStackTrace();}}public void onException(JMSException arg0) {isconnection = false;}}

ProducerTest.java

package queue;import javax.jms.JMSException; public class ProducerTest { /** * @param args * @throws Exception * @throws JMSException */ public static void main(String[] args) throws JMSException, Exception{ ProducerTool producer = new ProducerTool(); producer.produceMessage("Hello, world!"); producer.close(); } }

ProducerTool.java

package queue;import javax.jms.Connection; import javax.jms.DeliveryMode; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.MessageProducer; import javax.jms.Session; import javax.jms.TextMessage; import org.apache.activemq.ActiveMQConnection; import org.apache.activemq.ActiveMQConnectionFactory; public class ProducerTool { private String user = ActiveMQConnection.DEFAULT_USER; private String password = ActiveMQConnection.DEFAULT_PASSWORD; private String url = ActiveMQConnection.DEFAULT_BROKER_URL; private String subject = "myqueue"; private Destination destination = null; private Connection connection = null; private Session session = null; private MessageProducer producer = null; // 初始化 private void initialize() throws JMSException, Exception { ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory( user, password, url); connection = connectionFactory.createConnection(); session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); destination = session.createQueue(subject); producer = session.createProducer(destination); producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); } // 发送消息 public void produceMessage(String message) throws JMSException, Exception { initialize(); TextMessage msg = session.createTextMessage(message); connection.start(); System.out.println("Producer:->Sending message: " + message); producer.send(msg); System.out.println("Producer:->Message sent complete!"); } // 关闭连接 public void close() throws JMSException { System.out.println("Producer:->Closing connection"); if (producer != null) producer.close(); if (session != null) session.close(); if (connection != null) connection.close(); } }

 

topic模式：

ConsumerTest.java

package topic;import javax.jms.JMSException;public class ConsumerTest implements Runnable {static Thread t1 = null;/** * @param args * @throws InterruptedException * @throws InterruptedException * @throws JMSException * @throws InterruptedException */public static void main(String[] args) throws InterruptedException {t1 = new Thread(new ConsumerTest());t1.start();while (true) {System.out.println(t1.isAlive());if (!t1.isAlive()) {t1 = new Thread(new ConsumerTest());t1.start();System.out.println("重新启动");}Thread.sleep(5000);}// 延时500毫秒之后停止接受消息// Thread.sleep(500);// consumer.close();}public void run() {try {ConsumerTool consumer = new ConsumerTool();consumer.consumeMessage();while (ConsumerTool.isconnection) {}} catch (Exception e) {}}}

ConsumerTool.java

package topic;import javax.jms.Connection;import javax.jms.Destination;import javax.jms.ExceptionListener;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.MessageListener;import javax.jms.Message;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;public class ConsumerTool implements MessageListener, ExceptionListener {private String user = ActiveMQConnection.DEFAULT_USER;private String password = ActiveMQConnection.DEFAULT_PASSWORD;private String url = ActiveMQConnection.DEFAULT_BROKER_URL;private String subject = "mytopic";private Destination destination = null;private Connection connection = null;private Session session = null;private MessageConsumer consumer = null;public static Boolean isconnection = false;// 初始化private void initialize() throws JMSException, Exception {ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, password, url);connection = connectionFactory.createConnection();session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);destination = session.createTopic(subject);consumer = session.createConsumer(destination);}// 消费消息public void consumeMessage() throws JMSException, Exception {initialize();connection.start();consumer.setMessageListener(this);connection.setExceptionListener(this);isconnection = true;System.out.println("Consumer:->Begin listening...");// 开始监听// Message message = consumer.receive();}// 关闭连接public void close() throws JMSException {System.out.println("Consumer:->Closing connection");if (consumer != null)consumer.close();if (session != null)session.close();if (connection != null)connection.close();}// 消息处理函数public void onMessage(Message message) {try {if (message instanceof TextMessage) {TextMessage txtMsg = (TextMessage) message;String msg = txtMsg.getText();System.out.println("Consumer:->Received: " + msg);} else {System.out.println("Consumer:->Received: " + message);}} catch (JMSException e) {e.printStackTrace();}}public void onException(JMSException arg0) {isconnection = false;}}
