图片描述

贴上我的代码
//取消订单

@PostMapping("/cancel")
public  ResultVO cancel(@RequestParam("openid")String openid,
                        @RequestParam("orderId")String orderId)
{
    //TODO  不安全的做法，改进
   OrderDTO orderDTO= orderService.findOne(orderId);
    orderService.cancel(orderDTO);
    return ResultVOUtil.success();
}
