ActiveMQ应用笔记二：Producer与Consumer模板代码

接上一篇文章。

ActiveMQ成功部署运行后，就可以开发producer和consumer了。

在eclipse中新建Java项目，将ActiveMQ安装目录下lib中的jar包都引入项目，然后就可以编写producer和consumer。

注意：如果是测试代码，为了真实性，最好把producer和consumer分开写，而不是写在一个类中。

1.Producer:

package com.liyang.activemq;

import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.DeliveryMode;

import javax.jms.Destination;

import javax.jms.MessageProducer;

import javax.jms.Session;

import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class Sender_lion {

    public static void main(String[] args) {

        ConnectionFactory connectionFactory;

        Connection connection = null;

        Session session;

        Destination destination;

        MessageProducer producer;

        //参数为用户名，密码，MQ的url

        connectionFactory = new ActiveMQConnectionFactory(

                "smechina",

                "fulong",

                "tcp://localhost:61616");

        try {

            connection = connectionFactory.createConnection();

            connection.start();

            session = connection.createSession(Boolean.TRUE,

                    Session.AUTO_ACKNOWLEDGE);

            //*******注意：此处需修改为topic才能支持1对多发信息

           //destination = session.createQueue("FirstQueue");

           destination = session.createTopic("FirstTopic");

            // 得到消息生成者【发送者】

           producer = session.createProducer(destination);

           // ********设置是否持久化

           //producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

           producer.setDeliveryMode(DeliveryMode.PERSISTENT);

            //uandp是需要发送的消息

            String uandp = "liyang:fulong";

            sendMessage(session, producer,uandp);

            session.commit();

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            try {

                if (null != connection)

                    connection.close();

            } catch (Throwable ignore) {

            }

        }

    }

    public static void sendMessage(Session session, MessageProducer producer,String passport)

            throws Exception {

            // 发送10条消息

            for (int i = 0; i < 9; i++) {

            TextMessage message = session.createTextMessage("账号"+i+":" + passport);

                //System.out.println("账号是:" + passport);

            //可设置属性过滤

            //message.setStringProperty("receiver", "A");

                producer.send(message);

}

    }

}

1.Consumer:

package com.liyang.activemq;

import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.Destination;

import javax.jms.JMSException;

import javax.jms.Message;

import javax.jms.MessageConsumer;

import javax.jms.MessageListener;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.jms.Topic;

import org.apache.activemq.ActiveMQConnectionFactory;

public class Receiver_lion{

    public static void main(String[] args) {

        ConnectionFactory connectionFactory;

        Connection connection = null;

        Session session;

        Destination destination;

        MessageConsumer consumer;

        //参数为用户名，密码，MQ的url

        connectionFactory = new ActiveMQConnectionFactory(

        "smeguangdong",

                "fulong",

                "tcp://localhost:61616");

        try {

            connection = connectionFactory.createConnection();

            //---持久化订阅才使用下语句！！！！参数是clientid，设置该参数后MQ会记住该ID---

            connection.setClientID("guangdong"); 

            connection.start();

            session = connection.createSession(Boolean.FALSE,

                    Session.AUTO_ACKNOWLEDGE);

            //*******注意：此处需修改为topic才能支持1对多发信息

            //destination = session.createQueue("FirstQueue");

            destination = session.createTopic("FirstTopic");

            //创建普通消费者【接收者】，使用属性过滤

            //consumer = session.createConsumer(destination,"receiver = 'A'");

            //--------持久化订阅！！！！------第二个参数是client名

            consumer = session.createDurableSubscriber((Topic)destination,"guangdong");

            

            MessageListener ml = new MessageListener(){ 

            @Override 

            //设置监听器

            public void onMessage(Message m) { 

             TextMessage textMsg = (TextMessage) m; 

             try{

              System.out.println("收到消息:" + textMsg.getText()); 

             } catch (JMSException e) { 

              e.printStackTrace(); 

             } 

            } 

            };

            consumer.setMessageListener(ml);

            while (true) {

}

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            try {

                if (null != connection)

                    connection.close();

            } catch (Throwable ignore) {

            }

        }

    }

}
