Iterator<Map.Entry<String, List<DyDailyBillInput>>> iterator = collect.entrySet().iterator(); while (iterator.hasNext()){ Map.Entry<String, List<DyDailyBillInput>> next = iterator.next(); String orderId = next.getKey(); List<DyDailyBillInput> nextValue = next.getValue(); DyDailyOrderConfirm orderConfirm = convertOrderInfo(orderId, nextValue); Optional<DyDailyOrderConfirm> select = dyDailyOrderConfirmService.select(orderId, dataDate); if (select.isPresent()){ calcNewAmountThenUpdate(select.get(), orderConfirm, formatDataDate); }else { appendOrderInfoThenInsert(orderConfirm, nextValue.get(0).getOrderId(), formatDataDate); } } 解释一这段代码

具体来说，代码中的collect是一个类型为Map<String, List<DyDailyBillInput>>的集合，其中String表示键的类型，List<DyDailyBillInput>表示值的类型。代码首先通过调用entrySet()方法获取到collect中所有键值对的...

MyShoppingWebDataContext db = new MyShoppingWebDataContext(); protected void Page_Load(object sender, EventArgs e) { this.Title = "提交订单"; var user = db.User.Single(m => m.UserName == Session["userName"].ToString()); lblUserName.Text = Session["userName"].ToString(); lblName.Text = user.Name.ToString(); lblAddress.Text = user.Address.ToString(); lblPhone.Text = user.PhoneNum.ToString(); lblEmail.Text = user.Email.ToString(); float total = 0; lblGoods.Text = ""; for (int i = 0; i < int.Parse(Session["Num"].ToString()); i++) { var result= db.OrderItem.SingleOrDefault(m => m.OrderId == user.Id && m.ItemName == Session[i + "Name"].ToString() && m.status == 0); if (result != null) { var item = db.OrderItem.Single(m => m.OrderId == user.Id && m.ItemName == Session[i + "Name"].ToString() && m.status == 0); total += float.Parse((item.ItemPrice * float.Parse(item.ItemNum.ToString())).ToString()); lblGoods.Text += item.ItemName + " " + " " + "×" + item.ItemNum + "
"; } } lblTotalPrice.Text = total.ToString(); }

这是一个C#代码片段，它处理了一个页面加载。该页面显示了用户提交订单的表单，其中包含用户的个人信息、所订购商品的详细信息和总价。首先，代码从数据库中获取当前用户的信息并将其显示在页面上。...

for (UserPetOrder userPetOrder : list) { Long userId = userPetOrder.getUserId(); User user = userService.getById(userId); userPetOrder.setUser(user); Long petId = userPetOrder.getPetId(); Pet pet = petService.getById(petId); userPetOrder.setPet(pet); Long orderId = userPetOrder.getOrderId(); Order order = orderService.getById(orderId); userPetOrder.setOrder(order); }

此外，代码还获取了orderId属性，并通过orderService获取相应的Order对象，然后将其设置回原来的UserPetOrder对象中，使用setOrder()方法。这段代码的目的是将关联的用户、宠物和订单对象设置回每个...

解释 protected void Button1_Click(object sender, EventArgs e) { if (Session["UserId"] == null) { Response.Redirect("Default.aspx"); return; } string userid = Session["UserId"].ToString(); string spId = Request.QueryString["id"].ToString(); string orderId = Request.QueryString["oid"].ToString(); //实例化对象 Model.Comment en = new Model.Comment(); en.SPId = int.Parse(spId); en.UserId = int.Parse(userid); en.Orderid = int.Parse(orderId); en.Content = txtContent.Text; en.AddTime = DateTime.Now; //用户业务逻辑层 BLL.CommentBusiness busi = new BLL.CommentBusiness(); busi.Add(en); var orderB = new XiangXiDDBusiness(); orderB.UpdateState(en.Orderid); Alert.AlertAndRedirect("评论成功", "MyOrder.aspx"); }

在这个函数中，首先检查当前用户是否已登录，如果没有登录，则将页面重定向到默认页，return 语句用于退出函数。接下来，从 Session 和 QueryString 中获取一些参数值，用于构造实例化对象 Model.Comment。...

ModelAndView modelAndView = new ModelAndView(); //支付方式不同，渲染就不同, WXPAY_NATIVE使用codeUrl, ALIPAY_PC使用body Map<String, String> map = new HashMap<>(); if (bestPayTypeEnum == BestPayTypeEnum.WXPAY_NATIVE) { map.put("codeUrl", response.getCodeUrl()); map.put("orderId", orderId); map.put("returnUrl", wxPayConfig.getReturnUrl()); return ServerResponse.createBySuccess(map); }else if (bestPayTypeEnum == BestPayTypeEnum.ALIPAY_PC) { // map.put("body", response.getBody()); // template.process(map, new FileWriter("D:\\hello.html")); return ServerResponse.createBySuccess(response.getBody()); }

如果支付方式是WXPAY_NATIVE，那么将返回一个包含codeUrl、orderId和returnUrl的Map对象；如果支付方式是ALIPAY_PC，那么将返回response的body。其中，WXPAY_NATIVE使用codeUrl来生成支付二维码，而ALIPAY_PC则需要...

const processSaleOutBoundDetailArr = async (saleOutBoundArr, tokenData, accountData) => { let saleOutBoundDetailArr = [] if (saleOutBoundArr?.length > 0) { for (const item of saleOutBoundArr) { const saleOutBoundDetailRes = await getSaleOutBoundDetail( { id: item.id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain } ); if (saleOutBoundDetailRes.data.errcode === 0) { item.detailList = await processMaterial(item.id, saleOutBoundDetailRes.data.data.material_entity, tokenData, accountData) } saleOutBoundDetailArr.push(item) } } return saleOutBoundDetailArr } const processMaterial = async (orderId, materials, tokenData, accountData) => { let materialArr = [] if (materials && materials.length) { const materialIds = [...new Set(materials.map(item => item.material_id))]; const materialPromises = materialIds.map(id => { return getMaterialDetail({ id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }); }); const materialDetails = await Promise.all(materialPromises); materialArr = materials.map(material => { const materialDetail = materialDetails.find(detail => detail.data.errcode === 0 && detail.data.data.id === material.material_id); if (materialDetail) { const meterailData = materialDetail.data.data; material.model = meterailData.model material.fetch_category_id = meterailData.fetch_category_id material.tax_rate = meterailData.tax_rate material.orderId = meterailData.orderId } return material; }); } return materialArr; }; 优化这段代码

这段代码可以优化的地方有： 1. 使用for...of循环代替for循环，可以使代码更加简洁易读。... material.orderId = meterailData.orderId; } return material; }); return materialArr; };

@GetMapping("/comment/{goodsId}") public Result comment(@PathVariable Integer goodsId) { ArrayList<Object> comments = new ArrayList<>(); List<OrderItem> list = orderItemService.list(new QueryWrapper<OrderItem>().eq("goods_id", goodsId)); for (OrderItem orderItem : list) { Integer orderId = orderItem.getOrderId(); Orders orders = ordersService.getById(orderId); Integer userid = orders.getUserid(); User user = userService.getById(userid); if (StrUtil.isNotBlank(orderItem.getComment())) { comments.add(Dict.create().set("avatar", user.getAvatarUrl()).set("user", user.getNickname()).set("comment", orderItem.getComment())); } } return Result.success(comments); }

这段代码是一个基于Spring Boot框架的RESTful API接口，使用了@GetMapping注解，表示这个接口对应HTTP GET请求方式。接口路径是/comment/{goodsId}，其中{goodsId}是一个占位符，表示这个接口需要传入一个商品ID作为...

protected void btnOrder_Click(object sender, EventArgs e) { //检查库存 if (CheckStock() == false) { return; } DataSet ds = business.GetList(int.Parse(Session["UserId"].ToString())); List<string> missStock = new List<string>(); //循环片段购物车中的商品，添加订单数据 for (int I = 0; I < ds.Tables[0].Rows.Count; I++) { DataTable dt = ds.Tables[0]; BLL.XiangXiDDBusiness bus = new BLL.XiangXiDDBusiness(); XiangXiDD xx = new XiangXiDD(); xx.OrderID = DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + DateTime.Now.Millisecond.ToString(); xx.SPID = long.Parse(dt.Rows[I]["SPID"].ToString()); xx.SPName = dt.Rows[I]["SPName"].ToString(); xx.SPPrice = Convert.ToDecimal(dt.Rows[I]["SPPrice"].ToString()) * decimal.Parse(dt.Rows[I]["Num"].ToString()); xx.shuliang = Convert.ToInt32(dt.Rows[I]["Num"].ToString()); xx.Member = Session["UserName"].ToString(); bus.Add(xx); } business.ClearCart(int.Parse(Session["UserId"].ToString())); //清空购物车 Alert.AlertAndRedirect("结算成功！", "Default.aspx"); }

添加订单数据时，使用了 XiangXiDD 类来表示详细订单信息，订单编号(xx.OrderID)使用了当前时间的毫秒数构成，商品ID(xx.SPID)、商品名称(xx.SPName)、商品单价(xx.SPPrice)、商品数量(xx.shuliang)、会员名(xx....

@Service public class OrderService { @Resource private OrderMapper orderMapper; // @Autowired private RestTemplate restTemplate; @HystrixCommand(fallbackMethod = "queryOrderByIdFallback") public Order queryOrderById(Long orderId) { // 查询订单 Order order = orderMapper.findById(orderId); // String url = "http://user-service/user/" + order.getUserId(); User user = restTemplate.getForObject(url, User.class); // order.setUser(user); // 返回 return order; } public Order queryOrderByIdFallback(Long orderId){ System.out.println("查询Order ID出错了"); // 查询订单 Order order = orderMapper.findById((long) 101); // 托底数据 // 返回 return order; } }

这是一个使用了Spring Cloud和Hystrix的订单服务类，其中： - 通过@Resource注解注入了一个OrderMapper实例，用于查询数据库中的订单信息。 - 通过@Autowired注解注入了一个RestTemplate实例，用于调用用户服务的...

解释代码@Transactional public OrderInfo add(OrderInfo orderInfo) { // 1、生成最基本的订单信息，用户信息，放到orderInfo里 Long userId = orderInfo.getUserid(); //订单id：用户id+当前年月日时分+4位流水号 String orderId = userId + DateUtil.format(new Date(),"yyyyMMddHHmm") + RandomUtil.randomNumbers(4); orderInfo.setOrderid(orderId); //用户相关 UserInfo userInfo = userInfoService.findById(userId); orderInfo.setLinkaddress(userInfo.getAddress()); orderInfo.setLinkman(userInfo.getNickname()); orderInfo.setLinkphone(userInfo.getPhone()); // 2、保存订单表 orderInfo.setCreatetime(DateUtil.formatDateTime(new Date())); orderInfoMapper.insertSelective(orderInfo); List<OrderInfo> orderInfoList = orderInfoMapper.findByOrderId(orderId); // 3、查询订单里面的书籍列表，遍历 List<GoodsInfo> goodsList = orderInfo.getGoodsList(); for(GoodsInfo orderGoodsVO : goodsList){ Long goodsId = orderGoodsVO.getId(); //书籍信息 GoodsInfo goodsDetail = goodsInfoService.findById(goodsId); if(goodsDetail == null){ continue; } Integer orderCount = orderGoodsVO.getCount() == null?0:orderGoodsVO.getCount(); //想买多少 Integer goodsCount = goodsDetail.getCount() == null?0:goodsDetail.getCount(); //有多少库存 //4、扣库存 if(orderCount>goodsCount){ throw new CustomException(ResultCode.ORDER_PAY_ERROR); } goodsDetail.setCount(goodsCount - orderCount); //5、增加销量 int sales = goodsDetail.getSales()==null?0:goodsDetail.getSales(); goodsDetail.setSales(sales+orderCount); goodsInfoService.update(goodsDetail); //6、书籍订单关联表，增加关系 OrderGoodsRel orderGoodsRel = new OrderGoodsRel(); orderGoodsRel.setOrderid(orderInfoList.get(0).getId()); orderGoodsRel.setGoodsid(goodsId); orderGoodsRel.setCount(orderCount); orderGoodsRelMapper.insertSelective(orderGoodsRel); } //7、清空购物车 cartInfoService.empty(userId); return orderInfo; }

第一步是生成订单号（orderId），其中包含了用户id、当前时间、以及4位流水号。然后将用户信息（地址、联系人、电话）放入订单信息中。第二步是保存订单表，将订单信息插入到数据库中。然后查询订单信息，获取订单...

String orderId = user.getOrder().getOrderId();代替以上语句

可以使用以下代码替换原来的语句： ...String orderId = order.getOrderId(); 这样做的目的是为了提高代码的可读性和可维护性。将多个操作分解成单独的语句，使得代码更易于理解，也方便后续对代码的修改和调试。

SELECT <include refid="Base_Column_List"/>,a.${timeField} orderTime,b.ticket_no pendingTicketNo, f.rela_id returnGoodsId,f.ticket_no returnGoodsNo,c.is_classes FROM order_info AS a LEFT JOIN order_biz_rela AS b ON a.order_id = b.order_id and b.biz_type=1 and b.is_delete=1 INNER JOIN store_staff AS d ON a.create_user_id =d.user_id and a.store_id=d.store_id INNER JOIN buyer_info AS e ON a.buyer_id=e.buyer_id LEFT JOIN order_biz_rela AS f ON a.order_id = f.order_id and f.biz_type=2 and f.is_delete=1 INNER JOIN classes_biz c ON c.biz_id = a.order_id AND c.biz_type = 1 WHERE a.order_id=#{orderId} 优化

你可以为以下列添加索引：a.order_id、b.order_id、b.biz_type、b.is_delete、d.user_id、d.store_id、e.buyer_id、f.order_id、f.biz_type、f.is_delete、c.biz_id和c.biz_type。另外，你可以考虑使用INNER JOIN...

根据代码的上下文，order_result 是一个变量，它存储了 result['content']['orderResult'] 的值。根据之前的讨论，result['content']['orderResult'] 是一个字符串类型（str）。因此，可以推断出 order_...

/** * 支付页面 */ @RequestMapping("/order/pay") public String pay( @RequestParam(value = "orderId") Long orderId, Model model) { if (getLoginUser() == null) {//用户未登录 return "redirect:/"; } //订单不存在 Order order = orderService.get(orderId); if (order == null) { return renderNotFond(); } //登录用户既不是该订单的租客，也不是房东或者管理员，就不能看 if (!Objects.equals(getLoginUserId(), order.getCustomerUserId()) && !Objects.equals(getLoginUserId(), order.getOwnerUserId()) && !loginUserIsAdmin()){ return renderNotAllowAccsee(); } House house = houseService.get(order.getHouseId()); if (house == null) { //房子不存在 return renderNotFond(); } //该订单的房子信息 order.setHouse(houseService.get(order.getHouseId())); model.addAttribute("order",order); return "front/pay"; }

该方法接收一个参数：orderId 表示订单的 ID。该方法返回一个视图名称，展示支付页面。首先，该方法判断用户是否登录。如果用户未登录，则重定向到首页。接着，从 orderService 中获取 order 对象，如果该对象为空...

@RequestMapping("/selectByOrderId/{orderId}") public ServerResponseVo selectByOrderId(@PathVariable String orderId){ List<OrderDetails> orderDetails = iOrderDetailsService.list(new QueryWrapper<OrderDetails>().eq("order_id", orderId)); return ServerResponseVo.createBySuccess(orderDetails); }

这段代码看起来像是一个Java Spring框架...具体来说，它使用了Mybatis-Plus框架提供的list方法，查询订单详情表中所有orderId等于传入参数orderId的记录，并将查询结果封装到一个ServerResponseVo对象中返回给调用方。

@GetMapping("/detail") public Result detail(@RequestParam String orderid){ List<queryorder> detail = orderService.detail(orderid); if (detail != null) return Result.success(detail); return Result.error(); }

这是一个使用 Spring Boot 框架的 Java 后端接口，该接口使用 @GetMapping 注解，映射了一个 GET 请求路径为 "/detail"。该接口中有一个参数：orderid，使用 @RequestParam 注解标注，表明这个参数是从请求的 URL ...
