RabbitMQ之交换机及spring整合

交换机

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；

生产端代码

package com.jt.rabbitmqapi.exchange.direct;

import com.rabbitmq.client.Channel;

import com.rabbitmq.client.Connection;

import com.rabbitmq.client.ConnectionFactory;

public class Producer4DirectExchange {

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

        //1 创建ConnectionFactory

        ConnectionFactory connectionFactory = new ConnectionFactory();

        connectionFactory.setHost("192.168.147.146");

        connectionFactory.setPort();

        String routingKey = "test.direct";

//        String routingKey = "test.direct111"; //收不到

        //5 发送

        String msg = "Hello World RabbitMQ 4  Direct Exchange Message 111 ... ";

        channel.basicPublish(exchangeName, routingKey , null , msg.getBytes());

    }

}

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”

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

        channel.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

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

注：由于类配置写在代码里非常不友好，所以强烈建议大家使用配置文件配置
