RabbitMQ-广播模型

RabbitMQ-广播模型 使用案例

编写广播模型的代码

    // 广播模式生产者
    @Test
    void contextLoads3() throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setPort( 5672 );
        connectionFactory.setHost( "106.15.73.43" );
        connectionFactory.setUsername( "admin" );
        connectionFactory.setPassword( "123" );
        connectionFactory.setVirtualHost( "/rabbitmq_zhj" );
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare( "logs", "fanout" );
        channel.basicPublish( "logs", "", MessageProperties.PERSISTENT_TEXT_PLAIN, "hello fanout".getBytes() );
        channel.close();
        connection.close();
    }

编写广播模型的消费者代码并运行 消费者1

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setVirtualHost( "/rabbitmq_zhj" );
        connectionFactory.setPort( 5672 );
        connectionFactory.setHost( "106.15.73.43" );
        connectionFactory.setUsername( "admin" );
        connectionFactory.setPassword( "123" );
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare( "logs", "fanout" );
        String queueTemp = channel.queueDeclare().getQueue();
        channel.queueBind(queueTemp, "logs", "");
        channel.basicConsume( queueTemp, true , new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("消费者1： " + new String(body) );
            }
        });
    }

消费者2

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setVirtualHost( "/rabbitmq_zhj" );
        connectionFactory.setPort( 5672 );
        connectionFactory.setHost( "106.15.73.43" );
        connectionFactory.setUsername( "admin" );
        connectionFactory.setPassword( "123" );
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare( "logs", "fanout" );
        String queueTemp = channel.queueDeclare().getQueue();
        channel.queueBind(queueTemp, "logs", "");
        channel.basicConsume( queueTemp, true , new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("消费者2： " + new String(body) );
            }
        });
    }

消费者3

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setVirtualHost( "/rabbitmq_zhj" );
        connectionFactory.setPort( 5672 );
        connectionFactory.setHost( "106.15.73.43" );
        connectionFactory.setUsername( "admin" );
        connectionFactory.setPassword( "123" );
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare( "logs", "fanout" );
        String queueTemp = channel.queueDeclare().getQueue();
        channel.queueBind(queueTemp, "logs", "");
        channel.basicConsume( queueTemp, true , new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("消费者3： " + new String(body) );
            }
        });
    }

运行结果
