引出

---

1.rabbitmq队列方式的梳理，点对点，一对多；
2.发布订阅模式，交换机到消费者，以邮箱和手机验证码为例；
3.topic模式，根据规则决定发送给哪个队列；
4.rabbitmq回调确认，setConfirmCallback和setReturnsCallback；
5.死信队列，延迟队列，创建方法，正常—死信，设置延迟时间；

点对点(simple)

点对对方式传输

Work queues 一对多

1个生产者多个消费者

发布订阅/fanout模式

生产者通过fanout扇出交换机群发消息给消费者，同一条消息每一个消费者都可以收到。

以登陆验证码为例

rabbitmq_138">rabbitmq的配置

需要用到的常量

package com.tianju.auth.util;

/**
 * rabbitmq的常量
 */
public interface RabbitMqConstants {
    String MQ_MAIL_QUEUE="mq_email_queue";
    String MQ_PHONE_QUEUE="mq_phone_queue";
    String MQ_FANOUT_EXCHANGE="mq_fanout_exchange";

    // 参数 String name, boolean durable, boolean exclusive, boolean autoDelete
    boolean durable = true;
    boolean exclusive = false;
    boolean autoDelete = false;

}

RabbitMqConfig.java配置

邮箱队列，电话队列，交换机；

邮箱绑定交换机，电话绑定交换机；

创建队列参数说明：

参数	说明
name	字符串值，queue的名称。
durable	布尔值，表示该 queue 是否持久化。 持久化意味着当 RabbitMQ 重启后，该 queue 是否会恢复/仍存在。 另外，需要注意的是，queue 的持久化不等于其中的消息也会被持久化。
exclusive	布尔值，表示该 queue 是否排它式使用。排它式使用意味着仅声明他的连接可见/可用，其它连接不可见/不可用。
autoDelete	布尔值，表示当该 queue 没“人”（connection）用时，是否会被自动删除。

不指定 durable、exclusive 和 autoDelete 时，默认为 true 、 false 和 false 。表示持久化、非排它、不用自动删除。

创建交换机参数说明

参数	说明
name	字符串值，exchange 的名称。
durable	布尔值，表示该 exchage 是否持久化。 持久化意味着当 RabbitMQ 重启后，该 exchange 是否会恢复/仍存在。
autoDelete	布尔值，表示当该 exchange 没“人”（queue）用时，是否会被自动删除。

不指定 durable 和 autoDelete 时，默认为 true 和 false 。表示持久化、不用自动删除

消费者进行延迟消费

package com.tianju.mq.consumer;

import com.tianju.mq.constants.RabbitMqConstants;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Service;

import java.util.Date;

@Service
@Slf4j
public class UserConsumer {

    @RabbitListener(queues = RabbitMqConstants.MQ_DELAY_QUEUE)
    public void delayConsume(String msg){
        log.debug("[消费者消费信息:{},时间:{}",msg,new Date());
    }
}

总结

1.rabbitmq队列方式的梳理，点对点，一对多；
2.发布订阅模式，交换机到消费者，以邮箱和手机验证码为例；
3.topic模式，根据规则决定发送给哪个队列；
4.rabbitmq回调确认，setConfirmCallback和setReturnsCallback；
5.死信队列，延迟队列，创建方法，正常—死信，设置延迟时间；
