RabbitMq实现订单超时关闭

1、提供一个发送mq服务

@RequestMapping("/api/mq/rabbit")
public interface RabbitMqApiService {

    @RequestMapping("/sendMq")
    ResponseBO sendMq(RabbitCallBackBO rabbitCallBackBO);
}

2、在创建订单后，发送mq消息，这里很关键的地方是设置发送的延迟时间

RabbitCallBackBO rabbitCallBackBO = new RabbitCallBackBO();
                    rabbitCallBackBO.setCallBackHttpUrl("http://www.yyjunheng.com/client/task/order/timeout/cancel");
                    rabbitCallBackBO.setParams("{\"orderId\":" + order.getId() + "}");
                    rabbitCallBackBO.setMessageType(2);
                    rabbitCallBackBO.setDelayMillisecond(Long.valueOf(delayTime));//这里设置的延迟时间比如30分钟，30分钟后回调用http://www.yyjunheng.com/client/task/order/timeout/cancel
                    rabbitCallBackBO.setRouterKey("order.cancel");
                    rabbitCallBackBO.setExchangeName("exchange_business");
                    rabbitCallBackBO.setResultValue("code");
                    rabbitCallBackBO.setResultCode(0);
                    rabbitCallBackBO.setContentType(1);
                    rabbitCallBackBO.setHttpMethod(1);
                    String resultVO = HttpUtil.getInstance().postWithJson("http://www.yyjunheng.com/api/mq/rabbit/sendMq", JSON.toJSONString(rabbitCallBackBO));

3、提供一个取消订单的服务，就是上面mq消息的回调

@RequestMapping("/client/task")
public interface HealthTaskApiService {
    /**
     * 30分钟未支付订单 更新 为 取消订单 （门店下单 还原库存）
     */
    @GetMapping("/order/timeout/cancel")
    ResponseVO cancelTimeOutOrder(String orderId, HttpServletRequest request);

实现

  @Override
    public ResponseVO updateForCancelOrder(String orderId, HttpServletRequest request) {
        HealthOrder order = healthOrderDao.getUniqueOrder(orderId);
        //这个判断很重要，30分钟的回调回来如果订单不是待支付状态则不能取消订单，否则取消订单
        if (order == null || OrderStateConstant.ARREARAGE_ORDER.getStatusId() != order.getStatusId()) {
            throw new BusinessException(ErrorMsg.BillException.BIll_INFO_ERROR, false);
        }
        order.setStatusId(OrderStateConstant.CANCEL_ORDER.getStatusId());
        //业务代码....
        }
