队列模式

1.生产者代码：

package com.zzf.jms.queue;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class AppProducer {

    private static final  String url="tcp://192.168.1.6:61616";
    private static final  String queueName="queue-text";

    public static void main(String[] args) throws JMSException {

        //1.创建ConnectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);

        //((ActiveMQConnectionFactory) connectionFactory).setUserName("admin");
        //((ActiveMQConnectionFactory) connectionFactory).setPassword("admin");

        //2.创建Connection
        Connection connection = connectionFactory.createConnection();

        //3.启动连接
        connection.start();

        //4.创建会话
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        //5.创建接受者目标
        Destination destination = session.createQueue(queueName);

        //6.创建目标
        MessageProducer producer = session.createProducer(destination);

        for (int i = 0; i <10 ; i++) {
            //7.创建消息
            TextMessage textMessage=session.createTextMessage("消息内容"+i);
            //8.发送消息
            producer.send(textMessage);
            //
            System.out.println(textMessage.getText());
        }

        //9.关闭连接
        connection.close();
    }
}

上文的url可以改成“tcp://localhost:61616”,或者通过cmd->ipconfig

2.消费者代码：

package com.zzf.jms.queue;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class AppConsumer {

    private static final  String url="tcp://192.168.1.6:61616";
    private static final  String queueName="queue-text";

    public static void main(String[] args) throws JMSException {

        //1.创建ConnectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);

        //((ActiveMQConnectionFactory) connectionFactory).setUserName("admin");
        //((ActiveMQConnectionFactory) connectionFactory).setPassword("admin");

        //2.创建Connection
        Connection connection = connectionFactory.createConnection();

        //3.启动连接
        connection.start();

        //4.创建会话
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        //5.创建目标
        Destination destination = session.createQueue(queueName);

        //6.创建一个消费者
        MessageConsumer consumer = session.createConsumer(destination);

        //7.创建一个监听器
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接受消息："+textMessage.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }

            }
        });

        //8.关闭连接
       // connection.close();
    }

}

输出（启动消费者模式，再启动生产者）

（队列模式如上）

主题模式

1.发布者代码：

package com.zzf.jms.topic;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class AppProducer {

    private static final  String url="tcp://192.168.1.6:61616";
    private static final  String topicName="topic-text";

    public static void main(String[] args) throws JMSException {

        //1.创建ConnectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);

        //((ActiveMQConnectionFactory) connectionFactory).setUserName("admin");
        //((ActiveMQConnectionFactory) connectionFactory).setPassword("admin");

        //2.创建Connection
        Connection connection = connectionFactory.createConnection();

        //3.启动连接
        connection.start();

        //4.创建会话
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        //5.创建接受者目标
        Destination destination = session.createTopic(topicName);

        //6.创建目标
        MessageProducer producer = session.createProducer(destination);

        for (int i = 0; i <10 ; i++) {
            //7.创建消息
            TextMessage textMessage = session.createTextMessage("消息内容" + i);
            //8.发送消息
            producer.send(textMessage);
            //
            System.out.println(textMessage.getText());
        }

        //9.关闭连接
        connection.close();
    }
}

2.接受者代码：

package com.zzf.jms.topic;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class AppConsumer {

    private static final  String url="tcp://192.168.1.6:61616";
    private static final  String topicName="topic-text";

    public static void main(String[] args) throws JMSException {

        //1.创建ConnectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);

        //((ActiveMQConnectionFactory) connectionFactory).setUserName("admin");
        //((ActiveMQConnectionFactory) connectionFactory).setPassword("admin");

        //2.创建Connection
        Connection connection = connectionFactory.createConnection();

        //3.启动连接
        connection.start();

        //4.创建会话
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        //5.创建目标
        Destination destination = session.createTopic(topicName);

        //6.创建一个消费者
        MessageConsumer consumer = session.createConsumer(destination);

        //7.创建一个监听器
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接受消息："+textMessage.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }

            }
        });

        //8.关闭连接
       // connection.close();
    }

}

唯一需要改的地方是session.createTopic.

和队列模式一样，先启动接受者（启动一个以上），再启动发布者

每个接受者都接受到了发布者的发布信息（公众号）

注意：需要导入jar包：

        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.9.0</version>
        </dependency>

今天的文章AMQ初级使用（队列模式+主题模式）分享到此就结束了，感谢您的阅读。
