目标

1、交换机

2、RabbitMQ整合springCloud

交换机

蓝色区域===生产者

红色区域===Server：又称Broker，接受客户端的连接，实现AMQP实体服务

绿色区域===消费者

黄色区域===就是我们的交换机以及队列

由生产者投递信息到RabbitMQ Server里面某一个交换机对应的队列中，消费者则是从对应的队列中获取信息

交换机属性：

Name：交换机名称

Type：交换机类型 direct、topic、fanout、headers

Durability：是否需要持久化，true为持久化

Auto Delete：当最后一个绑定到Exchange上的队列删除后，自动删除该Exchange

Internal：当前Exchange是否用于RabbitMQ内部使用，默认为False

Arguments：扩展参数，用于扩展AMQP协议，定制化使用

直流交换机

直连交换机Direct Exchange（完全匹配路由key）

所有发送到Direct Exchange的消息会被转发到RouteKey中指定的Queue

注意：Direct模式可以使用RabbitMQ自带的Exchange：default Exchange，

所以不需要将Exchange进行任何绑定（binding）操作，消息传递时，RouteKey必须完全匹配才会被队列接收，否则该消息会被抛弃；

        Connection connection = connectionFactory.newConnection();

        //durable 是否持久化消息
        QueueingConsumer consumer = new QueueingConsumer(channel);
        //参数：队列名称、是否自动ACK、Consumer

        //5 发送

        String msg = "Hello World RabbitMQ 4  Direct Exchange Message 111 ... ";
        channel.basicPublish(exchangeName, routingKey , null , msg.getBytes());

    }
}

启动消费端

创建队列

交换机

进入交换机，里面也绑定了对应的队列

完了之后停掉消费端，先启动生产端  将信息投递到队列中，如果生产端和消费端的队列名不一致，消费端则拿不到信息

主题交换机

主题交换机Topic Exchange（匹配路由规则的交换机）

所有发送到Topic Exchange的消息被转发到所有关系RouteKey中指定Topic的Queue上；

Exchange将RouteKey和某Topic进行模糊匹配，此时队列需要绑定一个Topic；

注意：可以使用通配符进行模糊匹配

符号：“#” 匹配一个或者多个词

符号：“*” 匹配不多不少一个词

列如：

“log.#” 能够匹配到 “log.info.oa”

“log.*” 能够匹配到 “log.err”

消费端代码

package com.yuan.rabbitmqapi.exchange.topic;

        connectionFactory.setPort(5672);
        connectionFactory.setVirtualHost("/");

        connectionFactory.setAutomaticRecoveryEnabled(true);
        connectionFactory.setNetworkRecoveryInterval(3000);
        Connection connection = connectionFactory.newConnection();

        Channel channel = connection.createChannel();
        //4 声明
        String exchangeName = "test_topic_exchange";
        String exchangeType = "topic";
        String queueName = "test_topic_queue";
        String routingKey = "user.#";
//        String routingKey = "user.*";
        // 1 声明交换机
        channel.exchangeDeclare(exchangeName, exchangeType, true, false, false, null);
        // 2 声明队列
        channel.queueDeclare(queueName, false, false, false, null);
        // 3 建立交换机和队列的绑定关系:
        channel.queueBind(queueName, exchangeName, routingKey);

        //durable 是否持久化消息
        QueueingConsumer consumer = new QueueingConsumer(channel);
        //参数：队列名称、是否自动ACK、Consumer
        channel.basicConsume(queueName, true, consumer);
        //循环获取消息
        while(true){
            //获取消息，如果没有消息，这一步将会一直阻塞
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String msg = new String(delivery.getBody());
            System.out.println("收到消息：" + msg);
        }

        channel.basicPublish(exchangeName, routingKey3 , null , msg.getBytes());
        channel.close();
        connection.close();
    }
}

启动消费端，查看队列及交换机

 这里我们还可以点击交换机进去看它的一个绑定规则

 测试“log.#” 能够匹配到 “log.info.oa”

消费端代码

先启动生产端，再启动消费端

“log.*” 能够匹配到 “log.err”

 它的绑定规则改变了

后台只会收到了两条信息

输出交换机

输出交换机Fanout Exchange（不做路由）

不处理路由键，只需要简单的将队列绑定到交换机上；

发送到交换机的消息都会被转发到与该交换机绑定的所有队列上；

Fanout交换机转发消息是最快的

 消费端代码

package com.yuan.rabbitmqapi.exchange.fanout;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.QueueingConsumer;


public class Consumer4FanoutExchange {
    public static void main(String[] args) throws Exception {

        ConnectionFactory connectionFactory = new ConnectionFactory() ;

        connectionFactory.setHost("192.168.238.129");
        connectionFactory.setPort(5672);
        connectionFactory.setVirtualHost("/");

        connectionFactory.setAutomaticRecoveryEnabled(true);
        connectionFactory.setNetworkRecoveryInterval(3000);
        Connection connection = connectionFactory.newConnection();

        Channel channel = connection.createChannel();
        //4 声明
        String exchangeName = "test_fanout_exchange";
        String exchangeType = "fanout";
        String queueName = "test_fanout_queue";
        String routingKey = "";    //不设置路由键
        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);
        //参数：队列名称、是否自动ACK、Consumer
        channel.basicConsume(queueName, true, consumer);
        //循环获取消息
        while(true){
            //获取消息，如果没有消息，这一步将会一直阻塞
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String msg = new String(delivery.getBody());
            System.out.println("收到消息：" + msg);
        }
    }
}

            channel.basicPublish(exchangeName, "", null , msg.getBytes());
        }
        channel.close();
        connection.close();
    }
}

Binding-绑定

Exchange和Exchange、Queue之间的连接关系；

Binding中可以包含RoutingKey或者参数

Queue-消息队列

消息队列，实际存储消息数据

Durability：是否持久化

Durable：是，Transient：否

Auto delete：如选yes，代表当最后一个监听被移除之后，该Queue会自动被删除

Message-消息

服务器和应用程序之间传递的数据

本质上就是一段数据，由Properties和Payload（Body）组成

常用属性：delivery model、headers（自定义属性）

Message-其他属性

content_type、content_encoding、priority

correlation_id、reply_to、expiration、message_id

Timestamp、type、user_id、app_id、cluster_id

Virtual host-虚拟主机

虚拟地址，用于进行逻辑隔离，最上层的消息路由

一个Virtual Host里面可以有若干个Exchange和Queue

同一个Virtual Host里面不能有相同名称的Exchange或Queue

小结：

RabbitMQ的概念、安装与使用、管控台操作；

结合RabbitMQ的特性、Exchange、Queue、Binding、RoutingKey、Message进行核心API的讲解

RabbitMQ整合 SpringCloud实战

注意一点，在发送消息的时候对template进行配置mandatory=true保证监听有效

生产端还可以配置其他属性，比如发送重试，超时时间、次数、间隔等

消费端核心配置

u 首先配置手工确认模式，用于ACK的手工处理，这样我们可以保证消息的可靠性送达，或者在消费端消费失败的时候可以做到重回队列、根据业务记录日志等处理

u 可以设置消费端的监听个数和最大个数，用于控制消费端的并发情况

@RabbitListener注解的使用

消费端监听@RabbitListener注解，这个对于在实际工作中非常的好用

u @RabbitListener是一个组合注解，里面可以注解配置（@QueueBinding、@Queue、@Exchange）直接通过这个组合注解一次性搞定消费端交换机、队列、绑定、路由、并且配置监听功能等

}

启动消费端，创建队列。。

 绑定规则

分别运行测试的两个方法

testSender1

消费端后台成功接收到信息

testSender2
