ActiveMQ点对点模式

1.安装ActiveMQ服务器（略）

2.启动ActiveMQ,浏览器访问8161端口，默认账号admin/admin

3. 生产者代码

package test001;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
 * @Created by zhengqinfeng
 * @Description :
 * @Date : created in 23:44 2018/5/14
 */
public class ProducerMQ {
    public static void main(String[] args) throws JMSException {
        //创建MQ工厂
        ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616");
        //创建连接
        Connection connection = factory.createConnection();
        //启动连接
        connection.start();
        //创建会话工厂, false:表示不以事务方式进行提交; Session.AUTO_ACKNOWLEDGE 表示自动签收
//        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //Session.CLIENT_ACKNOWLEDGE:手动签收
        Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
        //创建队列
        Queue testMQ = session.createQueue("testMQ1");
        //创建生产者
        MessageProducer producer = session.createProducer(testMQ);
        //消息不持久化
//        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
        //持久化消息
        //producer.setDeliveryMode(DeliveryMode.PERSISTENT);
        for (int i = 0; i <= 10; i++) {
            System.out.println("###########我是生产者:"+i+"###############");
            sendMsg(session, producer, "我是生产者:" + i);
        }
            System.out.println("###########发送消息完毕###############");

}

private static void  sendMsg(Session session,MessageProducer producer,String i) throws JMSException {
        TextMessage textMessage = session.createTextMessage("hello activeMQ " + i);
        producer.send(textMessage);
    }
}

4.消费者代码

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
 * @Created by zhengqinfeng
 * @Description : 消费者
 * @Date : created in 12:47 2018/5/15
 */
public class ConsumerMQ {
    public static void main(String[] args) throws JMSException {
        System.out.println("消费者1");
        //创建MQ工厂
        ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616");
        //创建连接
        Connection connection = factory.createConnection();
        //启动连接
        connection.start();
        //创建会话工厂  AUTO_ACKNOWLEDGE:自动签收
//        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        // 手动签收
        Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
        //创建队列
        Queue testMQ = session.createQueue("testMQ1");
        //创建生产者
        MessageConsumer consumer = session.createConsumer(testMQ);

//第一种消费消息的方式
//        while (true) {
//            //获取消息
//            TextMessage message = (TextMessage) consumer.receive();
//            if (message != null) {
//                String text = message.getText();
//                System.out.println("消费者获取消息,text:" + text);
//                //手动签收,如果没有手动签收,消息还是会存在于队列中的(当然这是在Session.CLIENT_ACKNOWLEDGE模式下)
//                message.acknowledge();
//            } else {
//                break;
//            }
//        }
//        System.out.println("消费者获取消息完毕>>>>>>>>>>>>>>>>>>>..");

//第二种消费消息的方式
        consumer.setMessageListener(new MessageListener() {
            @Override
            public void onMessage(Message message) {
                TextMessage m = (TextMessage) message;
                try {
                    System.out.println("消费者获取消息:"+m.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        });
    }
}

　　启动消费者代码，然后修改System.out.println("消费者1")为System.out.println("消费者2")，再次启动。模拟测试两个消费者

启动生产者

再查看消费者1：

查看消费者2：

结论：消费1和消费者均摊消费testMQ1这个队列中的消息。
