RabbitMQ（五）之快速编写Hello RabbitMQ

一、搭建项目

创建Maven项目
导入rabbitmq包

        <dependency>
            <groupId>com.rabbitmq</groupId>
            <artifactId>amqp-client</artifactId>
            <version>3.6.5</version>
        </dependency>

二、代码

生产者代码

 public static void main(String[] args) {
        //1、 创建连接工厂
        ConnectionFactory connectionFactory = new ConnectionFactory();
        // RabbitMQ服务IP
        connectionFactory.setHost("127.0.0.1");
        // RabbitMQ服务端口
        connectionFactory.setPort(5672);
        // 选择VirtualHost
        connectionFactory.setVirtualHost("/");
        Connection connection;
        Channel channel=null;
        try {
            //2、 通过工厂创建连接
             connection = connectionFactory.newConnection();

            //3、通过连接创建Channel
             channel = connection.createChannel();

            String exchange = "";
            String routingKey = "te01";
            AMQP.BasicProperties basicProperties = null;
            for (int i = 0; i < 5; i++) {
                String body = "Producer:"+i;
                //发送消息
                channel.basicPublish(exchange, routingKey, basicProperties, body.getBytes());
            }

            // 按顺序关闭连接
            channel.close();
            connection.close();


        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }

    }

消费者代码

 public static void main(String[] args) {
        //1、 创建连接工厂
        ConnectionFactory connectionFactory = new ConnectionFactory();
        // RabbitMQ服务IP
        connectionFactory.setHost("127.0.0.1");
        // RabbitMQ服务端口
        connectionFactory.setPort(5672);
        // 选择VirtualHost
        connectionFactory.setVirtualHost("/");

        try {
            //2、 通过工厂创建连接
            Connection connection = connectionFactory.newConnection();

            //3、通过连接创建Channel
            Channel channel = connection.createChannel();
            //4、创建队列
            String queueName="te01";//队列名称
            channel.queueDeclare(queueName, true, false, false, null);
            //5、创建消费者
            QueueingConsumer queueingConsumer = new QueueingConsumer(channel);
            //6、配置channel
            channel.basicConsume(queueName,true,queueingConsumer);

            while (true){
                QueueingConsumer.Delivery delivery = queueingConsumer.nextDelivery();
                String body = new String(delivery.getBody());
                System.out.println("消费者："+body);
            }


        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }

三、查看控制界面
进入界面：http://127.0.0.1:15672
执行生产者代码，查看控制面板发送消息队列里面有10条消息

执行消费者代码，控制台则会打印出消息列队里面的消息，再次查看控制台消息列队则为0。
