Docker 搭建 RabbitMQ

  1. 拉取 RabbitMQ 的镜像执行命令 docker pull rabbitmq:3.7-management
  2. 执行运行命令 docker run -d --hostname rabbit --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 rabbitmq:3-management
  3. 打开浏览器访问 http://localhost:15672 ，账号：admim, 密码: admin

RabbitMQ 消息类型

Topic

topic 既可以实现 direct，也可实现 Fanout，topic 通过 routing_key 进行路由，key 可以存在两种特殊字符“ _ ”与“#”，用于做模糊匹配，其中“_”用于匹配一个单词，“#”用于匹配多个单词（可以是零个） *代表全部的

SpringBoot 整合

通过编写基本配置类，实现交换器和路由器绑定，和实现配置手动确认等，需要实现 RabbitTemplate.ConfirmCallback,RabbitTemplate.ReturnCallback 接口，实现接口的方法，还需设置配置文件。

基本配置类

import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.AcknowledgeMode;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;

/**
 * @ClassName RabbitConfig
 * @Author zhangjiahao
 * @Description RabbitMQ基本配置类
 * @Date $ $
 **/
@Configuration
@Slf4j
public class RabbitConfig implements RabbitTemplate.ConfirmCallback,RabbitTemplate.ReturnCallback {

    @Autowired
    private RabbitTemplate rabbitTemplate;
    @Autowired
    private CachingConnectionFactory connectionFactory;

    @PostConstruct
    public void init(){
        System.out.println("初始化rabbitmq");
        rabbitTemplate.setConfirmCallback(this);            // 指定 ConfirmCallback
        rabbitTemplate.setReturnCallback(this);             // 指定 ReturnCallback
    }

    /**
     * 如果消息到达 exchange, 则 confirm 回调, ack = true
     * 如果消息不到达 exchange, 则 confirm 回调, ack = false
     * 需要设置spring.rabbitmq.publisher-confirms=true
     * @param correlationData
     * @param ack
     * @param cause
     */
    @Override
    public void confirm(CorrelationData correlationData, boolean ack, String cause) {
        Message returnedMessage = correlationData.getReturnedMessage();
        if (ack){
            System.out.println("消息是否到达Exchange:{}" +  "消息成功到达Exchange");
        }else {
            System.out.println("消息是否到达Exchange:{}" + "消息到达Exchange失败");
        }

        if (!ack) {
            System.out.println("消息到达Exchange失败原因:{}"+ cause);
            // 根据业务逻辑实现消息补偿机制

        }
    }

    /**
     * exchange 到达 queue, 则 returnedMessage 不回调
     * exchange 到达 queue 失败, 则 returnedMessage 回调
     * 需要设置spring.rabbitmq.publisher-returns=true
     * @param message
     * @param replyCode
     * @param replyText
     * @param exchange
     * @param routingKey
     */
    @Override
    public void returnedMessage(Message message, int replyCode, String replyText, String exchange, String routingKey) {

        log.error("queuec处理失败");
        System.out.println("消息报文:{}"+ new String(message.getBody()));
        System.out.println("消息编号:{}"+ replyCode);
        System.out.println("描述:{}"+ replyText);
        System.out.println("交换机名称:{}"+exchange);
        System.out.println("路由名称:{}"+ routingKey);

        // 根据业务逻辑实现消息补偿机制
    }

    @Bean(name = "consumerlistenerContainer")
    public SimpleRabbitListenerContainerFactory mqConsumerlistenerContainer(){
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setConcurrentConsumers(2);
        factory.setMaxConcurrentConsumers(3);
        factory.setPrefetchCount(5);
        factory.setAcknowledgeMode(AcknowledgeMode.MANUAL);
        return factory;
    }

}

实现 Direct 队列

Direct 配置类

import io.renren.modules.generator.constant.MQConstant;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author zhangjiahao
 * @description DirectRabbitConfig
 * @date 2020-03-23 23:03:21
 */
@Configuration
public class DirectRabbitConfig {

    //队列 起名：TestDirectQueue
    @Bean
    public Queue directQueue() {
        return new Queue(MQConstant.MQQueueAndExchange.DIRECT_QUEUE, true);  //true 是否持久
    }

    //Direct交换机 起名：TestDirectExchange
    @Bean
    DirectExchange directExchange() {
        return new DirectExchange(MQConstant.MQQueueAndExchange.DIRECT_QUEUE_EXCHANGE);
    }

    //绑定  将队列和交换机绑定, 并设置用于匹配键：TestDirectRouting
    @Bean
    Binding bindingDirect() {
        return BindingBuilder.bind(directQueue()).to(directExchange()).with(MQConstant.MQQueueAndExchange.DIRECT_QUEUE_ROUTING_KEY);
    }
}

实现 Fanout 队列

Fanout 配置类

import io.renren.modules.generator.constant.MQConstant;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @ClassName FanoutRabbitConfig
 * @Author zhangjiahao
 * @Description //TODO $
 * @Date $ $
 **/
@Configuration
public class FanoutRabbitConfig {

    @Bean
    public Queue fanoutQueue(){
        return new Queue(MQConstant.MQQueueAndExchange.FANOUT_QUEUE);
    }

    @Bean
    public FanoutExchange fanoutExchange(){
        return new FanoutExchange(MQConstant.MQQueueAndExchange.FANOUT_QUEUE_EXCHANGE);
    }

    @Bean
    public Binding fanoutBinding(){
        return BindingBuilder.bind(fanoutQueue()).to(fanoutExchange());
    }
}

实现 Topic 队列

Topic 配置类

import io.renren.modules.generator.constant.MQConstant;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @ClassName TopicRabbitConfig
 * @Author zhangjiahao
 * @Description //TODO $
 * @Date $ $
 **/
@Configuration
public class TopicRabbitConfig {

    @Bean
    public Queue topicQueue(){
        return new Queue(MQConstant.MQQueueAndExchange.TOPIC_QUEUE);
    }

    @Bean
    public TopicExchange topicExchange(){
        return new TopicExchange(MQConstant.MQQueueAndExchange.TOPIC_QUEUE_EXCHANGE);
    }

    @Bean
    public Binding topicBinding(){
        return BindingBuilder.bind(topicQueue()).to(topicExchange()).with(MQConstant.MQQueueAndExchange.TOPIC_QUEUE_ROUTING_KEY);
    }
}

配置文件 yml

spring:
  rabbitmq:
    username: admin
    password: admin
    virtual-host: /
    host: 127.0.0.1
    port: 5672
    ## 手动确认
    publisher-confirms: true
    publisher-returns: true

编写消费者

消费端的代码基本一致，所以写个 Topic 的代码模板。

import com.alibaba.fastjson.JSON;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.rabbitmq.client.Channel;
import io.renren.modules.generator.constant.MQConstant;
import io.renren.modules.generator.entity.BrokerMessageLogEntity;
import io.renren.modules.generator.entity.SysMessageEntity;
import io.renren.modules.generator.service.BrokerMessageLogService;
import io.renren.modules.generator.service.SysMessageService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.Date;
import java.util.Map;

/**
 * @ClassName TopicConsumer
 * @Author zhangjiahao
 * @Description //TODO $
 * @Date $ $
 **/
@Slf4j
@Component
public class TopicConsumer {

    @Autowired
    private SysMessageService sysMessageService;
    @Autowired
    private BrokerMessageLogService brokerMessageLogService;

    @RabbitHandler
    @RabbitListener(queues = "topic_queue",containerFactory = "consumerlistenerContainer")
    public void topicConsumer(SysMessageEntity msg, Channel channel, Message message) throws IOException {
        System.out.println(msg.toString());
        BrokerMessageLogEntity one =
                brokerMessageLogService.getOne(new QueryWrapper<BrokerMessageLogEntity>().lambda().eq(BrokerMessageLogEntity::getMessageId, msg.getMessageId()).eq(BrokerMessageLogEntity::getStatus, 0));
        if (one == null) {
            one = new BrokerMessageLogEntity();
            one.setCreateTime(msg.getGmtCreate());
            one.setUpdateTime(msg.getGmtModified());
            one.setStatus("0");
            one.setMessageId(msg.getMessageId());
            one.setMessage(JSON.toJSONString(msg));
            one.setTryCount(MQConstant.MQ_TRY_COUNT);
            one.setNextRetry(new Date(System.currentTimeMillis() + MQConstant.MQ_TIME_SPACE));
        }
        try {
            log.info("正常处理数据，{}", msg);
            //处理完成 消息设置为已处理
            msg.setState(1);
            sysMessageService.updateById(msg);
            // MQ日志状态已处理
            one.setStatus("4");
            brokerMessageLogService.saveOrUpdate(one);
            channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
        } catch (Exception e) {
            if(one.getTryCount()<1){
                log.error("已超过尝试次数，在此失败{}",msg);
                msg.setState(-1);
                sysMessageService.updateById(msg);
                one.setStatus("-1");
                brokerMessageLogService.updateById(one);
                channel.basicReject(message.getMessageProperties().getDeliveryTag(), false);
            }
            // 消息重新放回队列
            try {
                one.setTryCount(one.getTryCount() - 1);
                one.setNextRetry(new Date(System.currentTimeMillis() + MQConstant.MQ_TIME_SPACE));
                brokerMessageLogService.updateById(one);
                System.out.println("消息[{}]处理失败，重新放回队列" + msg);
                channel.basicNack(message.getMessageProperties().getDeliveryTag(), false, true);
                e.printStackTrace();
            } catch (IOException ex) {
                log.error("消费失败,{}", msg);
                ex.printStackTrace();
            }

        }
    }
}

这里其他的 service 是用于记录 RabbitMQ 的日志，用于处理投递失败和消费失败的情况。

编写测试的生产者

@GetMapping("direct")
public R direct() {
    for (int i = 0; i < 11; i++) {
        SysMessageEntity sysMessageEntity = new SysMessageEntity();
        sysMessageEntity.setCreator("1");
        sysMessageEntity.setGmtCreate(new Date());
        sysMessageEntity.setGmtModified(new Date());
        sysMessageEntity.setMessageId(snowFlake.nextId() + "");
        sysMessageEntity.setModifier("1");
        sysMessageEntity.setName("测试消费direct-" + i);
        sysMessageEntity.setType(0);
        sysMessageEntity.setState(0);
        CommonCorrelationData commonCorrelationData = new CommonCorrelationData();
        commonCorrelationData.setId(sysMessageEntity.getMessageId());
        commonCorrelationData.setData(sysMessageEntity);
        sysMessageService.save(sysMessageEntity);
        rabbitTemplate.convertAndSend(MQConstant.MQQueueAndExchange.DIRECT_QUEUE_EXCHANGE,
                MQConstant.MQQueueAndExchange.DIRECT_QUEUE_ROUTING_KEY, sysMessageEntity,commonCorrelationData);

    }
    return R.ok();
}

@GetMapping("/fanout")
public R fanout() {
    for (int i = 0; i < 11; i++) {
        SysMessageEntity sysMessageEntity = new SysMessageEntity();
        sysMessageEntity.setCreator("1");
        sysMessageEntity.setGmtCreate(new Date());
        sysMessageEntity.setGmtModified(new Date());
        sysMessageEntity.setMessageId(snowFlake.nextId() + "");
        sysMessageEntity.setModifier("1");
        sysMessageEntity.setName("测试消费fanout-" + i);
        sysMessageEntity.setType(0);
        sysMessageEntity.setState(0);
        sysMessageService.save(sysMessageEntity);
        rabbitTemplate.convertAndSend(MQConstant.MQQueueAndExchange.FANOUT_QUEUE_EXCHANGE,
                MQConstant.MQQueueAndExchange.FANOUT_QUEUE_ROUTING_KEY, sysMessageEntity);
    }
    return R.ok();
}

@GetMapping("topic")
public R topic() {
    for (int i = 0; i < 11; i++) {
        SysMessageEntity sysMessageEntity = new SysMessageEntity();
        sysMessageEntity.setCreator("1");
        sysMessageEntity.setGmtCreate(new Date());
        sysMessageEntity.setGmtModified(new Date());
        sysMessageEntity.setMessageId(snowFlake.nextId() + "");
        sysMessageEntity.setModifier("1");
        sysMessageEntity.setName("测试消费topic-" + i);
        sysMessageEntity.setType(0);
        sysMessageEntity.setState(0);
        sysMessageService.save(sysMessageEntity);
        rabbitTemplate.convertAndSend(MQConstant.MQQueueAndExchange.TOPIC_QUEUE_EXCHANGE,
                MQConstant.MQQueueAndExchange.TOPIC_QUEUE_ROUTING_KEY, sysMessageEntity);

    }
    return R.ok();
}

关于 RabbitMQ 的 UI 界面设置

自定义 CorrelationData

因为 MQ 完全监控的原因，可以通过手动确认来处理投递失败的。

 /**

      * 如果消息到达 exchange, 则 confirm 回调, ack = true
      * 如果消息不到达 exchange, 则 confirm 回调, ack = false
      * 需要设置spring.rabbitmq.publisher-confirms=true
      * @param correlationData
      * @param ack
      * @param cause

      */
     @Override
     public void confirm(CorrelationData correlationData, boolean ack, String cause) {
         Message returnedMessage = correlationData.getReturnedMessage();
         if (ack){
             System.out.println("消息是否到达Exchange:{}" +  "消息成功到达Exchange");
         }else {
             System.out.println("消息是否到达Exchange:{}" + "消息到达Exchange失败");
         }

         if (!ack) {
             System.out.println("消息到达Exchange失败原因:{}"+ cause);
             // 根据业务逻辑实现消息补偿机制

         }
     }

通过重写 CorrelationData 来实现完全的监控。

 public class CorrelationData implements Correlation {
     private final SettableListenableFuture<CorrelationData.Confirm> future = new SettableListenableFuture();
     @Nullable
     private volatile String id;
     private volatile Message returnedMessage;

     public CorrelationData() {
     }

     public CorrelationData(String id) {
         this.id = id;
     }

     @Nullable
     public String getId() {
         return this.id;
     }

     public void setId(String id) {
         this.id = id;
     }

     public SettableListenableFuture<CorrelationData.Confirm> getFuture() {
         return this.future;
     }

     @Nullable
     public Message getReturnedMessage() {
         return this.returnedMessage;
     }

     public void setReturnedMessage(Message returnedMessage) {
         this.returnedMessage = returnedMessage;
     }

     public String toString() {
         return "CorrelationData [id=" + this.id + "]";
     }

     public static class Confirm {
         private final boolean ack;
         private final String reason;

         public Confirm(boolean ack, @Nullable String reason) {
             this.ack = ack;
             this.reason = reason;
         }

         public boolean isAck() {
             return this.ack;
         }

         public String getReason() {
             return this.reason;
         }

         public String toString() {
             return "Confirm [ack=" + this.ack + (this.reason != null ? ", reason=" + this.reason : "") + "]";
         }
     }
 }
