使用rabbitMq实现定时任务

场景：我的项目是一个内容管理中心，需要实现文章&广告的定时上下架功能。

实现可选方案有：

自己设计任务表进行定时轮询
redis的过期事件
rabbitMQ的TTL，通过设定消息的超时时间，交换机的x-dead-letter-exchange，超时后转移到待消费队列实现。
还有其他更多的方案，此处选择3

一图胜千言，方案设计图如下：

下面贴代码：

一、配置文件

配置rabbitmq，定义各交换机、队列，并根据routingkey进行绑定。为了更清晰不混乱，特意划分为几个配置文件：

RabbitConfigCommon：配置3个交换机、RabbitTemplate RabbitListenerContainerFactory 、定义各队列&交换机&路由建的名称。下面广告/公告上下架，每种消息一个配置文件：定义相应队列、路由键，绑定交换机，设置绑定策略和参数：

RabbitConfigForAdvOff、RabbitConfigForAdvOn 、RabbitConfigForArticleOff、RabbitConfigForArticleOn、RabbitConfigForDeathFinal（最终死信队列配置）

四、测试类

package com.pld.content.manager.controller.mq;

import com.pld.common.util.MsgResult;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Date;

/**mqtest
 * @author tlj
 * @date 2019/9/29
 */
@RestController
//@Api(value = "mqtest", tags = "mqtest")
public class MqTestController {
    @Autowired
    private TriggerProducer triggerProducer;

    public String sendOrder(){
        System.out.println("消息发送时间:"+System.currentTimeMillis());
       /**orderProducer.sendArticleOnTrigger();
        orderProducer.sendArticleOffTrigger();
        orderProducer.sendAdvOnTrigger();*/
        TriggerTaskInfo req = new TriggerTaskInfo();
        req.setId("03d7cb2c75044dfcac0be830aa17dda2");
        req.setUserId("admin");
        long duration = 10000*1L;
        Date triggerTime = new Date(System.currentTimeMillis()+duration);
        req.setTriggerTime(triggerTime);
        triggerProducer.sendAdvOffTrigger(duration,req);
        return "sendOrder";
    }

    @GetMapping(value = "/backend/mqtest")
//    @ApiOperation(value = "mqtest", notes = "mqtest")
    public MsgResult<String> mqtest() {

        return MsgResult.successStatic( sendOrder());
    }
}

五、其他

任务bean：

/**
 * @author tlj
 * @date 2019/12/31
 */
@Data
public class TriggerTaskInfo implements Serializable{
    // 业务表主键
    private String id;
    // 操作人id
    private String userId;

    private Date triggerTime;


}

其他业务service略...........
