如何使用：

//订单列表
    @GetMapping("/list")
    public ResultInfo<List<OrderDTO>> list(@RequestParam("openid") String openid,
                                         @RequestParam(value = "page",defaultValue = "0") Integer page,
                                         @RequestParam(value = "size", defaultValue = "10") Integer size){
        if(StringUtils.isEmpty(openid)){
            log.error("【查询订单列表】openid为空");
            throw new SellException(ResultEnum.PARAM_ERROR);
        }
        PageRequest request=new PageRequest(page,size);
        Page<OrderDTO> orderDTOPage=orderService.findList(openid,request);
        return ResultInfoUtil.success(orderDTOPage.getContent());
    }
   //订单详情
    @GetMapping("/detail")
    public ResultInfo<OrderDTO> detail(@RequestParam("openid") String openid,
                                     @RequestParam("orderId") String orderId){
        OrderDTO orderDTO=buyerService.findOrderOne(openid,orderId);
        return ResultInfoUtil.success(orderDTO);
    }
    //取消订单
    @PostMapping("/cancel")
    public ResultInfo cancel(@RequestParam("openid") String openid,
                           @RequestParam("orderId") String orderId){
        buyerService.cancelOrder(openid,orderId);
        return ResultInfoUtil.success();
    }
