RabbitMQ简介及AMQP协议
RabbitMQ安装与使用
RabbitMQ核心概念
与SpringBoot整合
保障100%的消息可靠性投递方案落地实现

1-2 RabbitMQ简介

初识RabbitMQ

RabbitMQ是一个开源的消息代理和队列服务器
用来通过普通协议在完全不同的应用之间共享数据
RabbitMQ是使用Erlang语言来编写的
并且RabbitMQ是基于AMQP协议的

RabbitMQ简介

目前很多互联网大厂都在使用RabbitMQ
RabbitMQ底层采用Erlang语言进行编写
开源、性能优秀，稳定性保障
与SpringAMQP完美的整合、API丰富
集群模式丰富，表达式配置，HA模式，镜像队列模型
保证数据不丢失的前提做到高可靠性、可用性
AMQP全称：Advanced Message Queuing Protocol
AMQP翻译：高级消息队列协议

AMQP协议模型

1-3 RabbitMQ安装

学习笔记

0.安装准备
官网地址：http://www.rabbitmq.com/
安装Linux必要依赖包<Linux7>
下载RabbitMQ安装包
进行安装，修改相关配置文件
vim /etc/hostname
vim /etc/hosts

1.安装Erlang
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get install erlang erlang-nox

2.安装RabbitMQ
echo 'deb http://www.rabbitmq.com/debian/ testing main' | sudo tee /etc/apt/sources.list.d/rabbitmq.list
wget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc | sudo apt-key add -
sudo apt-get install rabbitmq-server

3.安装RabbitMQ web管理插件
sudo rabbitmq-plugins enable rabbitmq_management
sudo systemctl restart rabbitmq-server
访问：http://localhost:15672
默认用户名密码：guest/guest

4.修改RabbitMQ配置
vim /usr/lib/rabbitmq/lib/rabbitmq_server-3.5.7/ebin/rabbit.app
比如修改密码、配置等等；例如：loopback_users中的<<"guest">>，只保留guest
服务启动：rabbitmq-server start &
服务停止：rabbitmqctl app_stop

1-4 RabbitMQ概念

RabbitMQ的整体架构

RabbitMQ核心概念

Server：又称Broker，接受客户端的连接，实现AMQP实体服务
Connection：连接，应用程序与Broker的网络连接
Channel：网络信道

几乎所有的操作都在Channel中进行
Channel是进行消息读写的通道
客户端可建立多个Channel
每个Channel代表一个会话任务
Message：消息

服务器和应用程序之间传送的数据，由Properties和Body组成
Properties可以对消息进行修饰，比如消息的优先级、延迟等高级特性
Body则就是消息体内容
Virtual host：虚拟机

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
Exchange：交换机，接收消息，根据路由键转发消息到绑定的队列
Binding：Exchange和Queue之间的虚拟连接，binding中可以包含routing key
Routing key：一个路由规则，虚拟机可用它来确定如何路由一个特定消息
Queue：也称为Message Queue，消息队列，保存消息并将它们转发给消费者

RabbitMQ消息的流转过程

第二章：RabbitMQ使用

2-1 发送消息

SpringBoot与RabbitMQ集成

引入相关依赖
对application.properties进行配置

创建名为rabbitmq-producer的maven工程pom如下

 * 描述: 订单实体<br>
 * 时间: 2018/09/06<br>
 *
 * @author zc
 */
public class Order implements Serializable{

    private static final long serialVersionUID = 6771608755338249746L;

    private String id;

    private String name;
    /**
     * 存储消息发送的唯一标识
     */
    private String messageId;

    public Order() {
    }

    public Order(String id, String name, String messageId) {
        this.id = id;
        this.name = name;
        this.messageId = messageId;
    }

    @Override
    public String toString() {
        return "Order{" +
                "id='" + id + ''' +
                ", name='" + name + ''' +
                ", messageId='" + messageId + ''' +
                '}';
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {

        return messageId;
    }

    public void setMessageId(String messageId) {
        this.messageId = messageId;
    }
}

2.编写OrderSender类

 * 描述: 订单消息发送者<br>
 * 时间: 2018/09/06<br>
 *
 * @author zc
 */
@Component
public class OrderSender {

    private RabbitTemplate rabbitTemplate;

    @Autowired
    public OrderSender(
            RabbitTemplate rabbitTemplate) {
        this.rabbitTemplate = rabbitTemplate;
    }

    /**
     * 发送订单
     *
     * @param order 订单
     * @throws Exception 异常
     */
    public void send(Order order) throws Exception {

        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(order.getMessageId());

        // exchange：交换机
        // routingKey：路由键
        // message：消息体内容
        // correlationData：消息唯一ID
        this.rabbitTemplate.convertAndSend("order-exchange", "order.a", order, correlationData);
    }

}

3.编写application.properties类

第三章：可靠性投递

3-1 设计方案

保障100%消息投递成功设计方案（一）

3-2 代码详解

/**
 * <br>
 * 标题: 订单消息发送者<br>
 * 描述: 订单消息发送者<br>
 * 时间: 2018/09/06<br>

 */
@Component
public class OrderSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;
    @Autowired
    private BrokerMessageLogMapper brokerMessageLogMapper;
    /**
     * 回调方法：confirm确认
     */
    private final RabbitTemplate.ConfirmCallback confirmCallback = new RabbitTemplate.ConfirmCallback() {

/**

 */
@Service
public class OrderService {

    @Autowired
    private OrderMapper orderMapper;
    @Autowired
    private BrokerMessageLogMapper brokerMessageLogMapper;
    @Autowired
    private OrderSender orderSender;

    /**
     * 创建订单
     *
     * @param order 订单
     */
    public void create(Order order) {
        // 当前时间
        Date orderTime = new Date();
        // 业务数据入库
        this.orderMapper.insert(order);
        // 消息日志入库
        BrokerMessageLogPO messageLogPO = new BrokerMessageLogPO();
        messageLogPO.setMessageId(order.getMessageId());
        messageLogPO.setMessage(FastJsonConvertUtils.convertObjectToJson(order));
        messageLogPO.setTryCount(0);

        this.brokerMessageLogMapper.insert(messageLogPO);
        // 发送消息
        this.orderSender.send(order);
    }
}

3.编写RetryMessageTask类

package com.myimooc.rabbitmq.ha.task;

import com.myimooc.rabbitmq.entity.Order;
import com.myimooc.rabbitmq.ha.constant.Constants;
import com.myimooc.rabbitmq.ha.dao.mapper.BrokerMessageLogMapper;
import com.myimooc.rabbitmq.ha.dao.po.BrokerMessageLogPO;
import com.myimooc.rabbitmq.ha.producer.OrderSender;
import com.myimooc.rabbitmq.ha.util.FastJsonConvertUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * <br>
 * 标题: 重发消息定时任务<br>
 * 描述: 重发消息定时任务<br>
 * 时间: 2018/09/07<br>
 *
 * @author zc
 */
@Component
public class RetryMessageTask {

    private Logger logger = LoggerFactory.getLogger(getClass());

    @Autowired
    private OrderSender orderSender;
    @Autowired
    private BrokerMessageLogMapper brokerMessageLogMapper;

    /**
     * 启动完成3秒后开始执行，每隔10秒执行一次
     */
    @Scheduled(initialDelay = 3000, fixedDelay = 10000)
    public void retrySend() {
        logger.debug("重发消息定时任务开始");
        // 查询 status = 0 和 timeout 的消息日志
        List<BrokerMessageLogPO> pos = this.brokerMessageLogMapper.listSendFailureAndTimeoutMessage();
        for (BrokerMessageLogPO po : pos) {
            logger.debug("处理消息日志：{}",po);
            if (po.getTryCount() >= Constants.MAX_RETRY_COUNT) {
                // 更新状态为失败
                BrokerMessageLogPO messageLogPO = new BrokerMessageLogPO();
                messageLogPO.setMessageId(po.getMessageId());
                messageLogPO.setStatus(Constants.OrderSendStatus.SEND_FAILURE);
                this.brokerMessageLogMapper.changeBrokerMessageLogStatus(messageLogPO);
            } else {
                // 进行重试，重试次数+1
                this.brokerMessageLogMapper.updateRetryCount(po);
                Order reSendOrder = FastJsonConvertUtils.convertJsonToObject(po.getMessage(), Order.class);
                try {
                    this.orderSender.send(reSendOrder);
                } catch (Exception ex) {
                    // 异常处理
                    logger.error("消息发送异常：{}", ex);
                }
            }
        }
        logger.debug("重发消息定时任务结束");
    }
}

4.编写ApplicationTest类

package com.myimooc.rabbitmq.ha;

import com.myimooc.rabbitmq.entity.Order;
import com.myimooc.rabbitmq.ha.service.OrderService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.UUID;

/**
 * <br>
 * 标题: 订单创建测试<br>
 * 描述: 订单创建测试<br>
 * 时间: 2018/09/07<br>
 *
 * @author zc
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTest {

    @Autowired
    private OrderService orderService;

    @Test
    public void testCreateOrder(){
        Order order = new Order();
        order.setId(String.valueOf(System.currentTimeMillis()));
        order.setName("测试创建订单");
        order.setMessageId(System.currentTimeMillis() + "$" + UUID.randomUUID().toString().replaceAll("-",""));
        this.orderService.create(order);
    }
