订单信息赋值

**cfmall-order/src/main/java/com/gyz/cfmall/order/service/impl/OrderServiceImpl.java**

计算订单总额，应付金额，设置积分等信息

    private OrderCreateTo createOrder() {
        OrderCreateTo createTo = new OrderCreateTo();
        //构建订单信息
        OrderEntity orderEntity = this.builderOrder();
        //构建订单项信息
        List<OrderItemEntity> itemEntityList = this.builderOrderItems(orderEntity.getOrderSn());
        //验价(计算价格、积分等信息)
        this.computePrice(orderEntity, itemEntityList);

        createTo.setOrder(orderEntity);
        createTo.setOrderItems(itemEntityList);
        return createTo;
    }

    private void computePrice(OrderEntity orderEntity, List<OrderItemEntity> itemEntityList) {
        //总价
        BigDecimal total = new BigDecimal("0.0");
        //优惠价
        BigDecimal coupon = new BigDecimal("0.0");
        BigDecimal intergration = new BigDecimal("0.0");
        BigDecimal promotion = new BigDecimal("0.0");
        //积分、成长值
        Integer integrationTotal = 0;
        Integer growthTotal = 0;

        //订单总额，叠加每一个订单项的总额信息
        for (OrderItemEntity orderItem : itemEntityList) {
            //优惠价格信息
            coupon = coupon.add(orderItem.getCouponAmount());
            promotion = promotion.add(orderItem.getPromotionAmount());

            //总价
            total = total.add(orderItem.getRealAmount());
            //积分信息和成长值信息
            integrationTotal += orderItem.getGiftIntegration();

        }
        //1、订单价格相关的

        orderEntity.setIntegration(integrationTotal);

        //设置删除状态(0-未删除，1-已删除)
        orderEntity.setDeleteStatus(0);
    }

订单状态、订单确认状态、自动确认时间赋值，见：设置订单相关的状态信息

    private OrderEntity builderOrder() {
        OrderEntity orderEntity = new OrderEntity();

        String orderSn = IdWorker.getTimeId();
        orderEntity.setOrderSn(orderSn);

        AddrAndFareVo addrAndFareVo = r.getData("data", new TypeReference<AddrAndFareVo>() {
        });

        //订单相关信息
        orderEntity.setFreightAmount(new BigDecimal(addrAndFareVo.getFare()));
        orderEntity.setReceiverName(addrAndFareVo.getMemberAddressVo().getName());
        orderEntity.setReceiverProvince(addrAndFareVo.getMemberAddressVo().getProvince());
        orderEntity.setReceiverCity(addrAndFareVo.getMemberAddressVo().getCity());
        orderEntity.setReceiverDetailAddress(addrAndFareVo.getMemberAddressVo().getDetailAddress());
        orderEntity.setReceiverPostCode(addrAndFareVo.getMemberAddressVo().getPostCode());
        orderEntity.setReceiverPhone(addrAndFareVo.getMemberAddressVo().getPhone());
        orderEntity.setReceiverRegion(addrAndFareVo.getMemberAddressVo().getRegion());

        //设置订单相关的状态信息
        orderEntity.setStatus(OrderStatusEnum.CREATE_NEW.getCode());
        orderEntity.setAutoConfirmDay(7);
        orderEntity.setConfirmStatus(0);

        return orderEntity;
    }
