2、JMS用戶變更消息生產者，使用jmsTemplate將用戶變更消息分別發送到queue與topic

public class AdvancedNotifyMessageProducer {

 private JmsTemplate jmsTemplate;
 private Destination notifyQueue;
 private Destination notifyTopic;

 public void sendQueue(final User user) {
  sendMessage(user, notifyQueue);
 }

 public void sendTopic(final User user) {
  sendMessage(user, notifyTopic);
 }

 

 使用jmsTemplate的send/MessageCreator()發送Map類型的消息並在Message中附加屬性用於消息過濾.

 private void sendMessage(final User user, Destination destination) {
  jmsTemplate.send(destination, new MessageCreator() {
   @Override
   public Message createMessage(Session session) throws JMSException {

    MapMessage message = session.createMapMessage();
    message.setString("userName", user.getName());
    message.setString("email", user.getEmail());

    message.setStringProperty("objectType", "user");

    return message;
   }
  });
 }

 public void setJmsTemplate(JmsTemplate jmsTemplate) {
  this.jmsTemplate = jmsTemplate;
 }

 public void setNotifyQueue(Destination notifyQueue) {
  this.notifyQueue = notifyQueue;
 }

 public void setNotifyTopic(Destination nodifyTopic) {
  this.notifyTopic = nodifyTopic;
 }
}

3、消息的異步被動接收者.

 使用Spring的MessageListenerContainer偵聽消息並調用本Listener進行處理.

public class AdvancedNotifyMessageListener implements MessageListener {

 

 private static Logger logger = LoggerFactory.getLogger(AdvancedNotifyMessageListener.class);

 

 MessageListener回調函數.

    @Override
 public void onMessage(Message message) {
  try {
   MapMessage mapMessage = (MapMessage) message;

   //打印消息詳情
   logger.info("UserName:" + mapMessage.getString("userName") + ", Email:" + mapMessage.getString("email")
     + ", ObjectType:" + mapMessage.getStringProperty("objectType"));
  } catch (Exception e) {
   logger.error("處理消息時發生異常.", e);
  }
 }
}
