用ActiveMQ實現JMS

一：ActiveMQ的安裝

1. 到http://activemq.apache.org/去下載個最新版(我下載的是5.5)

2. 解壓apache-activemq-5.4.2-bin.tar.gz文件 
3. 進入apache-activemq-5.4.2/bin目錄 
4. 啓動ActiveMQ，運行命令“./activemq start” 
   停止ActiveMQ，運行命令“./activemq stop” 
   查看ActiveMQ狀態，運行命令“./activemq status” 
5. 啓動好ActiveMQ之後，可以通過http://localhost:8161/admin來在瀏覽器裏訪問查看和管理消息

 

二：簡單的代碼試驗

 

下面是發送方的代碼：

 

package RestaurantSever;

import org.apache.activemq.ActiveMQConnection;  
import org.apache.activemq.ActiveMQConnectionFactory;  
  
import javax.jms.*;  
  
public class Sender {  
    public static void main(String[] args) throws JMSException {  
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");  
        Connection connection = connectionFactory.createConnection();  
        connection.start();  
  
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);  
        Destination destination = session.createQueue("myQueue");  
          
        MessageProducer producer = session.createProducer(destination);  
        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);  
  
        while(true) {  
            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();  
    }  
}

下面是接受方的代碼：

 package RestaurantSever;
import org.apache.activemq.ActiveMQConnection;  
import org.apache.activemq.ActiveMQConnectionFactory;  
  
import javax.jms.*;  
  
public class Receiver {  
    public static void main(String[] args) throws JMSException {  
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");  
        Connection connection = connectionFactory.createConnection();  
        connection.start();  
  
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);  
        Destination destination = session.createQueue("myQueue");  
        MessageConsumer consumer = session.createConsumer(destination);  
        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();  
                }  
            }  
        });  
          
//      session.close();  
//      connection.stop();  
//      connection.close();  
    }  
}

 

三：activeMQ的退出
退出activeMQ的話只需在運行 activemq.bat 的那個Cmd窗口按下Ctrl-C即可。
