ActiveMQ (二) JMS入门

JMS入门

前提：安装好了ActiveMQ  ActiveMQ安装

Demo结构：

首先pom.xml引入依赖：

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-client</artifactId>
    <version>5.13.4</version>
</dependency>

点对点模式：

消息生产者QueueProducer：

package com.zy.demo.queue;
 
import org.apache.activemq.ActiveMQConnectionFactory;
 
import javax.jms.*;
 
/**
 * 点对点模式 生产者
 */
public class QueueProducer {
    public static void main(String[] args) throws Exception {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = connectionFactory.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)
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建队列对象
        Queue queue = session.createQueue("test-queue");
        //6.创建消息生产者
        MessageProducer producer = session.createProducer(queue);
        //7.创建消息
        TextMessage textMessage = session.createTextMessage("点对点模式");
        //8.发送消息
        producer.send(textMessage);
        //9.关闭资源
        producer.close();
        session.close();
        connection.close();
    }
}

消息消费者QueueConsumer：

package com.zy.demo.queue;
 
import org.apache.activemq.ActiveMQConnectionFactory;
 
import javax.jms.*;
 
/**
 * 点对点模式 消费者
 */
public class QueueConsumer {
    public static void main(String[] args) throws Exception {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = connectionFactory.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)
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建队列对象
        Queue queue = session.createQueue("test-queue");
        //6.创建消息消费
        MessageConsumer consumer = session.createConsumer(queue);
 
        //7.监听消息
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接收到消息：" + textMessage.getText());
                } catch (JMSException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });
        //8.等待键盘输入
        System.in.read();
        //9.关闭资源
        consumer.close();
        session.close();
        connection.close();
    }
}

发布订阅模式：

消息生产者TopicProducer：

package com.zy.demo.toptic;
 
import org.apache.activemq.ActiveMQConnectionFactory;
 
import javax.jms.*;
 
/**
 * 发布/订阅模式 生产者
 */
public class TopicProducer {
    public static void main(String[] args) throws Exception {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = connectionFactory.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)
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建主题对象
        Topic topic = session.createTopic("test-topic");
        //6.创建消息生产者
        MessageProducer producer = session.createProducer(topic);
        //7.创建消息
        TextMessage textMessage = session.createTextMessage("发布订阅模式");
        //8.发送消息
        producer.send(textMessage);
        //9.关闭资源
        producer.close();
        session.close();
        connection.close();
    }
}

消息消费者TopicConsumer：

package com.zy.demo.toptic;
 
import org.apache.activemq.ActiveMQConnectionFactory;
 
import javax.jms.*;
 
public class TopicConsumer {
    public static void main(String[] args) throws Exception {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://192.168.25.128:61616");
        //2.获取连接
        Connection connection = connectionFactory.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)
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建主题对象
        //Queue queue = session.createQueue("test-queue");
        Topic topic = session.createTopic("test-topic");
        //6.创建消息消费
        MessageConsumer consumer = session.createConsumer(topic);
 
        //7.监听消息
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接收到消息：" + textMessage.getText());
                } catch (JMSException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });
        //8.等待键盘输入
        System.in.read();
        //9.关闭资源
        consumer.close();
        session.close();
        connection.close();
    }
}
