ActiveMQ 入门实战(2)--Java 操作 ActiveMQ

本文主要介绍使用 JMS 1.1 API 来操作 ActiveMQ，文中所使用到的软件版本：Java 1.8.0_191、ActiveMQ "Classic" 5.16.2、ActiveMQ Artemis 2.17.0。

1、Java 操作 ActiveMQ "Classic"

使用 JMS 1.1 的 API 操作 ActiveMQ "Classic"。

1.1、引入依赖

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
    <version>5.16.2</version>
</dependency>

1.2、发送消息

1.2.1、发送到 Queue

public static void sendToQueue() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    //连接池
    PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
    pooledConnectionFactory.setConnectionFactory(activeMQConnectionFactory);

    Connection connection = pooledConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);

    Destination destination = session.createQueue("testQueue");
    MessageProducer producer = session.createProducer(destination);
    //消息持久化
    producer.setDeliveryMode(DeliveryMode.PERSISTENT);
    for (int i = 1; i <= 10; i++) {
        TextMessage message = session.createTextMessage("消息" + i);

        producer.send(message);
        System.out.println("已发送的消息：" + message.getText());
    }
    producer.close();
    session.close();
    connection.close();
    pooledConnectionFactory.stop();
}

1.2.2、发送到 Queue(事务)

public static void sendToQueueTransaction() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

    MessageProducer producer = null;
    try {
        Destination destination = session.createQueue("testQueue");
        producer = session.createProducer(destination);
        producer.setDeliveryMode(DeliveryMode.PERSISTENT);
        for (int i = 1; i <= 10; i++) {
            TextMessage message = session.createTextMessage("事务消息" + i);

            producer.send(message);
            System.out.println("已发送的消息：" + message.getText());
        }
        session.commit();
    } catch (JMSException e) {
        session.rollback();
        e.printStackTrace();
    } finally {
        producer.close();
        session.close();
        connection.close();
    }
}

1.2.3、发送到 Topic

public static void sendToTopic() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

    Destination destination = session.createTopic("testTopic");
    MessageProducer producer = session.createProducer(destination);
    producer.setDeliveryMode(DeliveryMode.PERSISTENT);
    for (int i = 1; i <= 10; i++) {
        TextMessage message = session.createTextMessage("消息" + i);
        producer.send(message);
        System.out.println("已发送的消息：" + message.getText());
    }
    producer.close();
    session.close();
    connection.close();
}

1.2.4、发送到 Topic(事务)

public static void sendToTopicTraction() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

    Destination destination = session.createTopic("testTopic");
    MessageProducer producer = session.createProducer(destination);
    producer.setDeliveryMode(DeliveryMode.PERSISTENT);
    try {
        for (int i = 1; i <= 10; i++) {
            TextMessage message = session.createTextMessage("事务消息" + i);
            producer.send(message);
            System.out.println("已发送的消息：" + message.getText());
        }
        session.commit();
    } catch (JMSException e) {
        session.rollback();
        e.printStackTrace();
    } finally {
        producer.close();
        session.close();
        connection.close();
    }
}

}

1.3、消费者

1.3.1、从 Queue 中消费消息

public static void recevieFromQueue() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    //连接池
    PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
    pooledConnectionFactory.setConnectionFactory(activeMQConnectionFactory);
    Connection connection = pooledConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);

    Destination destination = session.createQueue("testQueue");

    MessageConsumer consumer = session.createConsumer(destination);
    consumer.setMessageListener(message -> {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("接受到的消息：" + textMessage.getText());
            textMessage.acknowledge();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    });
}

1.3.2、从 Queue 中消费消息(事务)

public static void recevieFromQueueTransction() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

    Destination destination = session.createQueue("testQueue");

    MessageConsumer consumer = session.createConsumer(destination);
    AtomicInteger index = new AtomicInteger();
    try {
        consumer.setMessageListener(message -> {
            TextMessage textMessage = (TextMessage) message;
            try {
                System.out.println("接受到的消息：" + textMessage.getText());
                index.getAndIncrement();
                //每10条提交一次
                if (index.get() % 10 == 0) {
                    session.commit();
                }
            } catch (JMSException e) {
                e.printStackTrace();
            }

        });
    } catch (JMSException e) {
        session.rollback();
        e.printStackTrace();
    }
}

1.3.3、从 Topic 中消费消息

public static void recevieFromTopic() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.start();
    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

    Destination destination = session.createTopic("testTopic");

    MessageConsumer consumer = session.createConsumer(destination);
    consumer.setMessageListener(message -> {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("接受到的消息：" + textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    });
}

1.3.4、从 Topic 中消费消息(持久化订阅+事务)

对于 Topic，使用 MessageConsumer 消费消息，只能消费订阅时间之后的消息；JMS 允许订阅者创建一个可持久化的订阅（TopicSubscriber），这样，即使订阅者宕机恢复后，也能接收宕机时生产者发布的消息。

public static void recevieFromTopicDurable() throws JMSException {
    ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerURL);
    Connection connection = activeMQConnectionFactory.createConnection();
    connection.setClientID("12345678");
    connection.start();
    Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

    Topic topic = session.createTopic("testTopic");
    TopicSubscriber topicSubscriber = session.createDurableSubscriber(topic, "test");

    AtomicInteger index = new AtomicInteger();
    topicSubscriber.setMessageListener(message -> {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("接受到的消息：" + textMessage.getText());
            index.getAndIncrement();
            //每10条提交一次
            if (index.get() % 10 == 0) {
                session.commit();
            }
        } catch (JMSException e) {
            e.printStackTrace();
        }
    });
}
