@Component
@Slf4j
public class OrderTask {

    @Autowired
    private OrderMapper orderMapper;

    //每分钟执行一次.处理订单超时
    @Scheduled(cron = "0 * * * * ?")
    public void processTimeoutOrder() {
        log.info("OrderTask processTimeoutOrder");
        LocalDateTime localDateTime = LocalDateTime.now().plusMinutes(-15);
        List<Orders> ordersList = orderMapper.getByStatusAndOrderTimeLT(Orders.PENDING_PAYMENT, localDateTime);
        if (ordersList != null && ordersList.size() > 0) {
            for (Orders orders : ordersList) {
                orders.setStatus(Orders.CANCELLED);
                orders.setCancelTime(LocalDateTime.now());
                orders.setCancelReason("订单超时，自动取消");
                orderMapper.update(orders);
            }
        }
    }

    //每天凌晨一点触发一次，处理一直派送中的订单
    @Scheduled(cron = "0 0 1 * * ?")
    public void processDeliveryOrder() {
        log.info("OrderTask processDeliveryOrder");
        LocalDateTime localDateTime = LocalDateTime.now().plusMinutes(-60);
        List<Orders> ordersList = orderMapper.getByStatusAndOrderTimeLT(Orders.DELIVERY_IN_PROGRESS, localDateTime);
        if (ordersList != null && ordersList.size() > 0) {
            for (Orders orders : ordersList) {
                orders.setStatus(Orders.COMPLETED);
                orderMapper.update(orders);
            }
        }
