RabbitMQ五种模式(TOPICS模式)

Send.java

public class Send {
    public static String EXCHANGE_NAME = "test_exchange_topic";

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setVirtualHost("/zhang");
        factory.setUsername("zhang");
        factory.setPassword("zhang");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare(EXCHANGE_NAME, "topic");
        String message = "message";
        channel.basicPublish(EXCHANGE_NAME, "item.broadcast", null, message.getBytes());
        channel.close();
        connection.close();
    }
}

Recv.java

public class Recv {
    public static String QUEUE_NAME = "test_queue_topic_1";
    public static String EXCHANGE_NAME = "test_exchange_topic";

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setVirtualHost("/zhang");
        factory.setUsername("zhang");
        factory.setPassword("zhang");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare(
                QUEUE_NAME, false, false,
                false, null
        );
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "item.broadcast");
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "item.a");
        channel.basicQos(1);
        DefaultConsumer consumer = new DefaultConsumer(channel) {
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                String message = new String(body, "UTF-8");
                System.out.println(" [x] Received '" + message + "'");
                try {
                    Thread.sleep(2 * 1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                channel.basicAck(envelope.getDeliveryTag(), false);
            }
        };
        channel.basicConsume(QUEUE_NAME, false, consumer);
    }
}

Recv2.java

public class Recv2 {
    public static String QUEUE_NAME = "test_queue_topic_2";
    public static String EXCHANGE_NAME = "test_exchange_topic";

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setVirtualHost("/zhang");
        factory.setUsername("zhang");
        factory.setPassword("zhang");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare(
                QUEUE_NAME, false, false,
                false, null
        );
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "item.broadcast");
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "item.b");
        channel.basicQos(1);
        DefaultConsumer consumer = new DefaultConsumer(channel) {
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                String message = new String(body, "UTF-8");
                System.out.println(" [x] Received '" + message + "'");
                try {
                    Thread.sleep(2 * 1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                channel.basicAck(envelope.getDeliveryTag(), false);
            }
        };
        channel.basicConsume(QUEUE_NAME, false, consumer);
    }
