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：

</html>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。
