前言

设计订单过期，不能单纯靠Redis，需要兜底策略

代码实现：

import com.coolplay.trade.dto.req.CancelOrderReq;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.collections.CollectionUtils;
import org.springframework.data.redis.core.ZSetOperations;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.Set;
import java.util.concurrent.TimeUnit;


@Service
@Slf4j
public class OrderRedisDelayQueueOperator extends AbstractOrderScheduleDelayQueue {
  @Resource(name = "redisTemplate")
  private ZSetOperations<String, String> orderRedis;

  /**
  * 预售、现货生成订单15分钟后未支付，需要取消订单
  */
  private static final String DELAY_QUEUE_NAME = "order";

  /**
  * 每1秒执行一次
  */
  @Override
  @Scheduled(cron = "0/1 * * * * ? ")
  public void orderEventProcess() {
    if (!redisLock.tryLock(this.getClass().getSimpleName(), TimeUnit.MILLISECONDS, 10, 100)) {
      return;
    }
    Set<String> dq = orderRedis.range(DELAY_QUEUE_NAME, 0L, Long.MAX_VALUE);
    if (CollectionUtils.isEmpty(dq)) {
      return;
    }
    for (String orderNo : dq) {
      Double xs = orderRedis.score(DELAY_QUEUE_NAME, orderNo);
      Double now = System.currentTimeMillis() * 1.0;
      if (xs <= now) {
        log.info("{} timed out", orderNo);
        super.threadPoolTaskExecutor.execute(() -> {
          CancelOrderReq req = new CancelOrderReq();
          req.setOrderNo(orderNo);
          req.setCancelType(OrderActionEnum.TIME_OUT_CANCEL);
          orderService.cancelOrder(req);
        });
      } else {
        //log.info("{} no time out", orderNo);
        //如果最小的都没有过期，剩余的则不用处理了
      编程客栈  break;
      }
    }
  }


  public void addToRedis(String orderNo, long delayTime) {
    orderRedis.add(DELAY_QUEUE_NAME,编程客栈 orderNo, delayTime * 1.0);

  }

  public void removeFromRedis(String orderNo) {

    orderRedis.remove(DELAY_QUEUE_NAME, orderNo);
  }
}

兜底策略

/**
  * 取消订单--10分钟--20分钟执行一次
  */
  @XxlJob("cancelOrder20Minutes")
  public void cancelOrderTenMinutes() {
    log.info("*****[开始：下单十分钟以后系统自动取消订单]*****");
    Date start = DateUtil.dateRoll(new Date(), Calendar.MINUTE,-20);
    Date end = new Date();
   List<ClOrder> clorderList =clOrderMapper.selectListAllOrdrWaiting(start,end);
   if(ObjectUtil.isNotEmpty(clorderList)){
     for(int i=0;i<clorderList.size();i++){
       ClOrder clOrder = clorderList.get(i);
       if(ObjectUtil.isNotEmpty(clOrder)){
         Date orderTime = clOrder.GsDIwQKEgetOrderTime();
         long between = cn.hutool.core.date.DateUtil.between(orderTime, new Date(), DateUn编程客栈it.MINUTE);
         if(between>10){
           ClOrder clOrderTemp = new ClOrder();
           clOrderTemp.setOrderState("3");
           clOrderTemp.setId(clOrder.getId());
           clOrderTemp.setMemberId(clOrder.getMemberId());
           String msg="您的订单已经取消，订单金额已发放至您的账户请查收~";
           try {
             boolean b = orderService.cancelOrder(clOrderTemp,msg);
             if(!b){
               log.info("[订单失效：定时任务兜底策略更新失败]**订单ID: {}",clOrderTemp.getId());
             }
             log.info("[Redis订单取消订单失效，定时任务兜底策略生效]");
           }catch (Exception e){
             log.info("[订单失效：定时任务兜底策略更新失败]**订单ID: {}",clOrderTemp.getId());
             e.printStackTrace();
           }


         }
       }
     }
   }
    log.info("*****[结束：下单十分钟以后系统自动取消订单]*****");
  }
