activemq点对点

一：加入jar

<dependency>

<groupId>org.apache.activemq</groupId>

<artifactId>activemq-client</artifactId>

<version>5.13.4</version>

</dependency>

二：创建点对点模式生产者

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class producerQueue {
    public static void main(String[] args) throws JMSException {
        //1.创建连接工厂
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = activeMQConnectionFactory.createConnection();
        //3.启动连接
        connection.start();
        //4.获取session  (参数1：是否启动事务,参数2：消息确认模式)
        /*
            - AUTO_ACKNOWLEDGE = 1    自动确认
            - CLIENT_ACKNOWLEDGE = 2    客户端手动确认
            - DUPS_OK_ACKNOWLEDGE = 3    自动批量确认
            - SESSION_TRANSACTED = 0    事务提交并确认
         */
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建队列对象
        Queue queue = session.createQueue("teset_queue");
        //6.创建消息生产者
        MessageProducer producer = session.createProducer(queue);
        //7.创建消息
        TextMessage textMessage = session.createTextMessage("神奇的activemq");
        //8.发送消息
        producer.send(textMessage);
        //9.关闭资源
        producer.close();
        session.close();
        connection.close();
    }
}

三：创建点对点消费者

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;
import java.io.IOException;

public class ConsumerQueue {
    public static void main(String[] args) throws JMSException, IOException {
        //1.创建连接工厂
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = activeMQConnectionFactory.createConnection();
        //3.启动连接
        connection.start();
        //4.获取session  (参数1：是否启动事务,参数2：消息确认模式)
        /*
            - AUTO_ACKNOWLEDGE = 1    自动确认
            - CLIENT_ACKNOWLEDGE = 2    客户端手动确认
            - DUPS_OK_ACKNOWLEDGE = 3    自动批量确认
            - SESSION_TRANSACTED = 0    事务提交并确认
         */
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建队列对象
        Queue queue = session.createQueue("teset_queue");
        //6.创建消息消费者
        MessageConsumer consumer = session.createConsumer(queue);
        //7.监听消息
        consumer.setMessageListener(new MessageListener(){

            @Override
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接收到的消息："+textMessage.getText());
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
        });
        //8.等待键盘输入,目的让主线程等待监听程序
        System.in.read();
        //9.关闭资源
        consumer.close();
        session.close();
        connection.close();
    }
}
