本文介绍了一种将字符串形式的日期转换为Java Date对象的方法，并实现了商品总价、优惠价及折扣总额的计算逻辑。

Date stringToDate(String dateString) {
        Date dt = null;
        new String();
        if (dateString.contains("T")) {
            String codDateStr = dateString.replace("T", " ");
            if (codDateStr.contains("+")) {
                codDateStr = codDateStr.substring(0, codDateStr.indexOf("+"));
            }

            SimpleDateFormat[] sdfs = new SimpleDateFormat[]{new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS"), new SimpleDateFormat("yyyy-MM-dd HH:mm:ssZ"), new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"), new SimpleDateFormat("yyyy-MM-ddHH:mm:ss"), new SimpleDateFormat("yyyy-MM-dd")};
            SimpleDateFormat[] arr$ = sdfs;
            int len$ = sdfs.length;
            int i$ = 0;

            while(i$ < len$) {
                SimpleDateFormat sdf = arr$[i$];

                try {
                    dt = sdf.parse(codDateStr);
                    break;
                } catch (Exception var10) {
                    ++i$;
                }
            }
        }

        return dt;
    }
public String getCreateDate() {   #get回原始
  return this.createDate;
}

public Date findCreateDate() { # find经转化  妙
    return this.stringToDate(this.createDate);
}

价格计算
this.totalPrice = BigDecimal.ZERO;
        this.totalRePrice = BigDecimal.ZERO;
        this.totalDiscount = BigDecimal.ZERO;
        int len$;
        int i$;
        if (this.theSkus != null && this.theSkus.length > 0) {
            SKU[] arr$ = this.theSkus;
            len$ = arr$.length;

            for(i$ = 0; i$ < len$; ++i$) {
                SKU sku = arr$[i$];
                this.totalPrice = this.totalPrice.add(sku.getPrice().multiply(new BigDecimal(sku.getNum())));
                this.totalRePrice = this.totalRePrice.add(sku.getReprice().multiply(new BigDecimal(sku.getNum())));
                this.totalDiscount = this.totalDiscount.add(sku.getDiscount().multiply(new BigDecimal(sku.getNum())));
            }
        }


拷贝属性
org.springframework.beans.BeanUtils
this.foreach(new CartHandler() {
            public void execute(Suit suit, SkuType skuType, SKU sku) {
                SKU e = new SKU();
                if (suit != null) {
                    ;
                }

                BeanUtils.copyProperties(sku, e);
                result.add(e);
            }
        });
