activemq 的小实验

 package ch02.chat;

 import javax.jms.Connection;
 import javax.jms.ConnectionFactory;
 import javax.jms.Destination;
 import javax.jms.MapMessage;
 import javax.jms.MessageProducer;
 import javax.jms.Session;

 import org.apache.activemq.ActiveMQConnectionFactory;

 class Send
 {
     public static void main(String[] args) throws Exception {
         ConnectionFactory connectionFactory = new ActiveMQConnectionFactory();    

         Connection connection = (Connection) connectionFactory.createConnection();
         connection.start();    

         Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
         Destination destination = session.createQueue("my-queue");    

         MessageProducer producer = session.createProducer(destination);
         for(int i=0; i<3; i++) {    

             MapMessage message=session.createMapMessage();
             message.setLong("age",15 );
             message.setString("name", "zhangsa");
             Thread.sleep(1000);
             //通过消息生产者发出消息
             producer.send(message);
         }
         session.commit();
         session.close();
         connection.close();
     } 

 }

1.发送客户端，发送3个key-value的信息、

用localhost:8161查看message的内容：

3.开启消费进程

 package ch02.chat;

 import java.sql.Connection;

 import javax.jms.ConnectionFactory;
 import javax.jms.Destination;
 import javax.jms.JMSException;
 import javax.jms.MapMessage;
 import javax.jms.Message;
 import javax.jms.MessageConsumer;
 import javax.jms.MessageListener;
 import javax.jms.Session;

 import org.apache.activemq.ActiveMQConnectionFactory;

 public class Receive {

     public static void main(String[] args) throws JMSException {
         // TODO Auto-generated method stub
         ConnectionFactory  conFactory=new ActiveMQConnectionFactory();
        javax.jms.Connection con=conFactory.createConnection();
        con.start();
       final  Session session=con.createSession(false,Session.AUTO_ACKNOWLEDGE );
       Destination des=session.createQueue("my-queue");
       MessageConsumer consumer=session.createConsumer(des);
       consumer.setMessageListener(new MessageListener(){

         @Override
         public void onMessage(Message m) {
             // TODO Auto-generated method stub
             if(m instanceof MapMessage){
                 MapMessage mm=(MapMessage)m;
             try {
                 System.out.println(mm.getLong("age"));
                 System.out.println(mm.getString("name"));
             } catch (JMSException e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
             }

             }

         }

       });

     }

 }

查看信息没了，哈哈哈
