利用Spring與ActiveMQ整合傳送、接收訊息例項(Queue與Topic模式)
阿新 • • 發佈：2019-01-23
利用Spring與ActiveMQ整合傳送、接收訊息例項，同時使用Queue與Topic兩種模式。
1.執行環境：Win10+Eclipse Java EE IDE Oxygen Release (4.7.0)+jdk1.8
3.向topic傳送訊息的生產者TopicSender程式碼：
4.向queue傳送訊息的生產者QueueSender程式碼：public class TopicSender { @Resource private JmsTemplate jmsTopicTemplate; //傳送訊息 public void sendMessage(Destination destination,final String message) { System.out.println("TopicSender傳送訊息："+message); jmsTopicTemplate.send(destination, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { // TODO Auto-generated method stub return session.createTextMessage(message); } }); } }
5.接收topic訊息的消費者1：public class QueueSender { @Resource private JmsTemplate jmsQueueTemplate; //傳送訊息 public void sendMessage(Destination destination,final String message) { System.out.println("QueueSender傳送訊息："+message); jmsQueueTemplate.send(destination, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { // TODO Auto-generated method stub return session.createTextMessage(message); } }); } }
public class TopicReceiver1 implements MessageListener { /* * (非 Javadoc) <p>Title: onMessage</p> <p>Description: </p> * * @param arg0 * * @see javax.jms.MessageListener#onMessage(javax.jms.Message) */ @Override public void onMessage(Message message) { // TODO Auto-generated method stub TextMessage textMessage = (TextMessage) message; try { System.out.println("TopicReceiver1接收到訊息內容是：" + textMessage.getText()); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
6.接收topic訊息的消費者2：
public class TopicReceiver2 implements MessageListener {
/*
* (非 Javadoc) <p>Title: onMessage</p> <p>Description: </p>
*
* @param arg0
*
* @see javax.jms.MessageListener#onMessage(javax.jms.Message)
*/
@Override
public void onMessage(Message message) {
// TODO Auto-generated method stub
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("TopicReceiver2接收到訊息內容是：" + textMessage.getText());
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}public class QueueReceiver1 implements MessageListener {
/*
* (非 Javadoc) <p>Title: onMessage</p> <p>Description: </p>
*
* @param arg0
*
* @see javax.jms.MessageListener#onMessage(javax.jms.Message)
*/
@Override
public void onMessage(Message message) {
// TODO Auto-generated method stub
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("QueueReceiver1接收到訊息內容是：" + textMessage.getText());
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}public class QueueReceiver2 implements MessageListener {
/*
* (非 Javadoc) <p>Title: onMessage</p> <p>Description: </p>
*
* @param arg0
*
* @see javax.jms.MessageListener#onMessage(javax.jms.Message)
*/
@Override
public void onMessage(Message message) {
// TODO Auto-generated method stub
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("QueueReceiver2接收到訊息內容是：" + textMessage.getText());
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/applicationContext.xml")
public class ActivemqController {
@Resource
private QueueSender queueSender;
@Resource
private TopicSender topicSender;
@Resource
@Qualifier("queueDestination")
private Destination queueDestination;
@Resource
@Qualifier("topicDestination")
private Destination topicDestination;
@Test
public void testSend() {
for (int i = 0; i < 5; i++) {
queueSender.sendMessage(queueDestination, "queue生產者產生訊息：" + (i + 1));
}
for (int i = 0; i < 5; i++) {
topicSender.sendMessage(topicDestination, "topic生產者產生訊息：" + (i + 1));
}
}

</beans>程式配置好之後run as -> JUnit Test 可以看到執行結果：
可以看出queue的訊息只能被消費一次，topic的訊息可以由多個訂閱的消費者消費。
