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:
