新峰商城之订单（一）：确认页面开发

新峰商城订单从生成到处理结束，主要以下几个流程：

（1）提交订单（商城用户发起）

（2）订单入库（后台逻辑）

（3）支付订单（商城用户发起）

（4）订单处理（确认订单、取消订单、修改订单）

一、订单确认的前置步骤

通过购物车页面的结算按钮进入订单确认页面，如果购物车中无数据，则提示“购物车中无数据”，数据正常则执行settle()方法并进跳转，跳转路径为/shop-cart/settle,并在此控制器方法中进行订单确认页面中数据的查询和整合，其代码如下所示：

<div class="order_button fr"><th:block th:if="${itemsTotal == 0}"><input class="order_button_c" type="button" name="tip"onclick="tip()"value="去结算"/></th:block><th:block th:unless="${itemsTotal == 0}"><input class="order_button_d" type="button" name="settle"onclick="settle()"value="去结算"/></th:block>
</div>

其中tip(）方法和settle()方法代码如下所示：

/*** 购物车中数量为0时提示*/
function tip() {Swal.fire({text: "购物车中无数据，无法结算",icon: "error",iconColor:"#f05b72",});}
/*** 跳转至结算页面*/
function settle() {window.location.href = '/shop-cart/settle'}

二、订单确认页面显示主要数据

订单确认页不同于购物车中商品数据，还包括用户数据和支付数据，其详细信息如下图所示：

三、订单确认页面控制层

在ShoppingCartController类中增加settlePage()方法，用于处理/shop-cart/settle请求，并将数据带到订单确认页面进行渲染，代码如下所示：

@GetMapping("/shop-cart/settle")public String settlePage(HttpServletRequest request,HttpSession httpSession) {int priceTotal = 0;//从session中获取用户信息，包括收货信息NewBeeMallUserVO user = (NewBeeMallUserVO) httpSession.getAttribute(Constants.MALL_USER_SESSION_KEY);List<NewBeeMallShoppingCartItemVO> myShoppingCartItems = newBeeMallShoppingCartService.getMyShoppingCartItems(user.getUserId());if (CollectionUtils.isEmpty(myShoppingCartItems)) {//无数据则不跳转至结算页return "/shop-cart";} else {//总价for (NewBeeMallShoppingCartItemVO newBeeMallShoppingCartItemVO : myShoppingCartItems) {priceTotal += newBeeMallShoppingCartItemVO.getGoodsCount() * newBeeMallShoppingCartItemVO.getSellingPrice();}if (priceTotal < 1) {NewBeeMallException.fail("购物项价格异常");}}request.setAttribute("priceTotal", priceTotal);request.setAttribute("myShoppingCartItems", myShoppingCartItems);return "mall/order-settle";}

此方法查询商品信息并计算总价，然后将priceTotal和myShoppingCartItems两个对象放入request请求中，再跳转到order-settle页面。

四、订单确认页面制作

在resources/templates/mall目录中新增订单确认页order-settle.html，模板代码如下所示：

此页面中主要渲染的数据有收货信息、商品信息、价格信息等数据，收货信息直接读取session对象中的数据，商品信息获取同购物车中的商品数据获取类似，页面读取myShoppingCartItems数据，使用th:each循环语法将商品信息进行渲染。价格信息中运费为0，总价字段直接读取priceTotal字段。
