ActiveMQ入门程序

环境准备：Linux上安装好了activemq并启动。
1、创建一个普通的maven工程，导入依赖：

		<dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.11.2</version>
        </dependency>

2、创建生产者（点对点模式）：

package com.soft.producter;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
 * Created by Administrator on 2020/9/24 0024.
 */
public class producter01 {

    public static void main(String[] args) throws JMSException {
        // 创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "admin", "tcp://192.168.25.128:61616");
        // 创建连接
        Connection connection = connectionFactory.createConnection();
        // 启动连接
        connection.start();
        // 创建会话
        Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
        // 创建队列
        Queue queue_01 = session.createQueue("queue_01");
        // 创建生产者
        MessageProducer producer = session.createProducer(queue_01);
        // 创建消息
        TextMessage textMessage = session.createTextMessage("hello queue_01");
        // 发送消息
        producer.send(textMessage);
        // 提交事务
        session.commit();
        // 释放资源
        session.close();
        connection.close();
    }
}

3、创建消费者（点对点模式）：

package com.soft.consumer;

import org.apache.activemq.ActiveMQConnectionFactory;

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

/**
 * Created by Administrator on 2020/9/24 0024.
 */
public class Consumer01 {
    public static void main(String[] args) throws JMSException, IOException {
        // 创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "admin", "tcp://192.168.25.128:61616");
        // 创建连接
        Connection connection = connectionFactory.createConnection();
        // 启动连接
        connection.start();
        // 创建会话
        final Session session = connection.createSession(true, 1);
        // 创建队列
        Queue queue_01 = session.createQueue("queue_01");
        // 创建消费者
        MessageConsumer consumer = session.createConsumer(queue_01);
        //监听queue_01
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                try {
                    TextMessage textMessage = (TextMessage) message;
                    System.out.println(textMessage.getText());
                    // 提交事务
                    session.commit();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
        
        //线程阻塞
        System.in.read();
        // 释放资源
        session.close();
        connection.close();
    }
}

5、生产者（发布订阅模式入门代码）：

package com.soft.producter;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
 * Created by Administrator on 2020/9/24 0024.
 */
public class Producter02 {
    public static void main(String[] args) throws JMSException {
        // 创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "admin", "tcp://192.168.25.128:61616");
        // 创建连接
        Connection connection = connectionFactory.createConnection();
        // 启动连接
        connection.start();
        // 创建会话
        Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
        //创建Topic
        Topic topic_01 = session.createTopic("topic_01");
        // 创建生产者
        MessageProducer producer = session.createProducer(topic_01);
        // 创建消息
        TextMessage textMessage = session.createTextMessage("hello topic_01");
        // 发送消息
        producer.send(textMessage);
        // 提交事务
        session.commit();
        // 释放资源
        session.close();
        connection.close();
    }
}

6、消费者（发布订阅模式入门代码）：

package com.soft.consumer;

import org.apache.activemq.ActiveMQConnectionFactory;

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

/**

 */
public class Consumer02 {
    public static void main(String[] args) throws JMSException, IOException {
        // 创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "admin", "tcp://192.168.25.128:61616");
        // 创建连接
        Connection connection = connectionFactory.createConnection();
        // 启动连接
        connection.start();
        // 创建会话
        final Session session = connection.createSession(true, 1);
        //创建Topic
        Topic topic_01 = session.createTopic("topic_01");
        // 创建消费者
        MessageConsumer consumer = session.createConsumer(topic_01);
        //监听queue_01
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                try {
                    TextMessage textMessage = (TextMessage) message;
                    System.out.println(textMessage.getText());
                    // 提交事务
                    session.commit();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
        //线程阻塞
        System.in.read();
        // 释放资源
        session.close();
        connection.close();
    }
}
