RabbitMQ+spring boot 快速启动

流程： 首先是获取连接工厂 ConnectionFactory --> 获取一个连接 Connection --> 通过连接建立数据通信 信道 Channel，用 Channel 发送或接收消息。

定义和赋值 RabbitMQ 的配置

public interface RabbitMQCommon {

    final static String RABBITMQ_HOST = "192.168.0.7";
    final static int RABBITMQ_PORT = 5672;
    final static String RABBITMQ_DEFAULT_VIRTUAL_HOST = "/";

    public final static String RABBITMQ_USERNAME = "guest";
    public final static String RABBITMQ_PASSWORD = "guest";
}

消费端代码：

/**
 * 快速开始：消费者
 */
@Slf4j
public class Consumer {
    private static final Logger log = LoggerFactory.getLogger(Consumer.class);
    
    public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost(RabbitMQCommon.RABBITMQ_HOST);
        connectionFactory.setPort(RabbitMQCommon.RABBITMQ_PORT);
        connectionFactory.setVirtualHost(RabbitMQCommon.RABBITMQ_DEFAULT_VIRTUAL_HOST);

        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
//          queueName， durable, exclusive, autoDelete, arguments
        channel.queueDeclare("test1001", true, false, false, null);
        QueueingConsumer queueingConsumer = new QueueingConsumer(channel);
//         queueName,  autoAck, Consumer callback
        channel.basicConsume("test1001", true, queueingConsumer);
        log.info("消费端启动啦~");
        while (true) {
            Delivery delivery = queueingConsumer.nextDelivery();
            String msg = new String(delivery.getBody());
            log.info("消费端接收到：{}", msg);
        }
    }

}

生产端代码：

/**
 * 快速开始：生产者
 */
@Slf4j
public class Procuder {

    private static final Logger log = LoggerFactory.getLogger(Procuder.class);
    
    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost(RabbitMQCommon.RABBITMQ_HOST);
        connectionFactory.setPort(RabbitMQCommon.RABBITMQ_PORT);
        connectionFactory.setVirtualHost(RabbitMQCommon.RABBITMQ_DEFAULT_VIRTUAL_HOST);

        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();

        for (int i = 0; i < 5; i++) {
            String msg = "hello RabbitMQ + " + i;
            log.info("生产者发送消息：{}", msg);
            channel.basicPublish("", "test1001", null, msg.getBytes());
        }
        log.info("生产者发送消息完毕");
        channel.close();
        connection.close();
    }
}

run运行消费端的代码

打开管控台，看到这个队列创建成功了

image image

运行生产端的代码，看到如下日志

image

点击这个queue进去查看到刚才有消息发送过来了

image

在idea查看消费端的日志

image

刚才生产端发送的消息已被消费端消费，至此，快速启动demo已完毕
