1.9 RabbitMQ-Fanout Exchange demo

demo的前置條件和1.5-RabbitMQ-速入門demo 一樣。
Fanout Exchange的基本概念：

1.1 生產者代碼

package com.star.movie.exchange.fanout;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.QueueingConsumer;
import com.rabbitmq.client.QueueingConsumer.Delivery;
import com.star.movie.common.Constant;

/**
 * @Description：Consumer4FanoutExchange

 **/
public class ConsumerFanoutExchange {

    public static void main(String[] args) throws Exception {

        //2 創建Connection
        Connection connection = Constant.getConnection();
        Channel channel = connection.createChannel();
        //4 聲明
        String exchangeName = "test_fanout_exchange";
        String exchangeType = "fanout";
        String queueName = "test_fanout_queue";
        //不設置路由鍵
        String routingKey = "";
        channel.exchangeDeclare(exchangeName, exchangeType, true, false, false, null);
        channel.queueDeclare(queueName, false, false, false, null);
        channel.queueBind(queueName, exchangeName, routingKey);
        //durable 是否持久化消息
        QueueingConsumer consumer = new QueueingConsumer(channel);
        //參數：隊列名稱、是否自動ACK、Consumer
        channel.basicConsume(queueName, true, consumer);
        //循環獲取消息
        while(true){
            //獲取消息，如果沒有消息，這一步將會一直阻塞
            Delivery delivery = consumer.nextDelivery();
            String msg = new String(delivery.getBody());
            System.out.println("收到消息：" + msg);
        }
    }
}

1.2 消費者代碼

package com.star.movie.exchange.fanout;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.star.movie.common.Constant;

/**
 * @Description：Producer4FanoutExchange
 * @author:kaili
 * @Date: 2019-04-21 22:48
 **/
public class ProducerFanoutExchange {

    public static void main(String[] args) throws Exception {
        //2 創建Connection
        Connection connection = Constant.getConnection();
        //3 創建Channel
        Channel channel = connection.createChannel();
        //4 聲明
        String exchangeName = "test_fanout_exchange";
        //5 發送
        for(int i = 0; i < 10; i ++) {
            String msg = "Hello World RabbitMQ 4 FANOUT Exchange Message ...";
            channel.basicPublish(exchangeName, "", null , msg.getBytes());
        }
        channel.close();
        connection.close();
    }
}

1.3.1 啓動消費者代碼

test_fanout_exchange交換機和隊列test_fanout_queue直接綁定沒有幫i的那個健
1.3.2 關閉消費者代碼，啓動生產者代碼

生產者投遞的10條消息全部投遞到test_fanout_queue隊列上了

1.3.3 啓動消費者代碼

消費了10條消息
