ActiveMQ_Java代码编写producer和consumer

如何安装ActiveMQ：文章链接

---

依赖包，最好跟你安装的ActiveMQ版本相同

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
    <version>5.15.10</version>
</dependency>

ActiveMQ生产者代码

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JMSProducer {

    private final static String DEFAULT_BROKER_HOST = "tcp://192.168.253.132:61616";
    private final static String USER_NAME = "admin";
    private final static String PASSWORD = "admin";
    private final static String QUEUE_NAME = "queue_one";

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

        // 创建链接工厂
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(USER_NAME, PASSWORD, DEFAULT_BROKER_HOST);
        // 通过链接工厂获得connection并启动
        Connection connection = activeMQConnectionFactory.createConnection();
        connection.start();
        //创建会话session，两个参数，第一个为事务，第二个是签收
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //创建目的地，是队列还是主题
        Queue queue = session.createQueue(QUEUE_NAME);
        // 创建生产者
        MessageProducer producer = session.createProducer(queue);
        //循环发送5条消息
        for (int i = 0; i < 5; i++) {
            //创建消息
            TextMessage textMessage = session.createTextMessage("Hello ActiveMQ" + i);
            // 发送消息
            producer.send(textMessage);
        }

        // 关闭链接
        producer.close();
        session.close();
        connection.close();

    }
}

ActiveMQ消费者代码

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JMSConsumer {
    private final static String DEFAULT_BROKER_HOST = "tcp://192.168.253.132:61616";
    private final static String USER_NAME = "admin";
    private final static String PASSWORD = "admin";
    private final static String QUEUE_NAME = "queue_one";


    public static void main(String[] args) throws JMSException {
        // 创建链接工厂
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(USER_NAME, PASSWORD, DEFAULT_BROKER_HOST);
        // 通过链接工厂获得connection并启动
        Connection connection = activeMQConnectionFactory.createConnection();
        connection.start();
        //创建会话session，两个参数，第一个为事务，第二个是签收
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //创建目的地，是队列还是主题
        Queue queue = session.createQueue(QUEUE_NAME);
        //创建消费者
        MessageConsumer consumer = session.createConsumer(queue);
        //循环接受消息
        while (true) {
            TextMessage receive = (TextMessage) consumer.receive();
            System.out.println("receive.getText() --> " + receive.getText());
        }
    }
}

ActiveMQ消费者代码(监听方式)

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JMSConsumer {
    private final static String DEFAULT_BROKER_HOST = "tcp://192.168.253.132:61616";
    private final static String USER_NAME = "admin";
    private final static String PASSWORD = "admin";
    private final static String QUEUE_NAME = "queue_one";


    public static void main(String[] args) throws JMSException {
        // 创建链接工厂
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(USER_NAME, PASSWORD, DEFAULT_BROKER_HOST);
        // 通过链接工厂获得connection并启动
        Connection connection = activeMQConnectionFactory.createConnection();
        connection.start();
        //创建会话session，两个参数，第一个为事务，第二个是签收
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //创建目的地，是队列还是主题
        Queue queue = session.createQueue(QUEUE_NAME);
        //创建消费者
        MessageConsumer messageConsumer = session.createConsumer(queue);
        //设置监听器
        messageConsumer.setMessageListener(message -> {
            if (message instanceof TextMessage) {
                TextMessage receive = (TextMessage) message;
                try {
                    System.out.println("receive.getText() --> " + receive.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        });
        System.in.read();
    }
}
