中小型电商系统商品属性设计与实现

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了中小型电商系统商品属性设计与实现相关的知识，希望对你有一定的参考价值。
这两年做过不少的小型电商系统，有的卖衣服，有的卖鞋子，有的卖电器，甚至还有些卖虚拟服务的。不同商品的属性千差万别，为了减少以后卖xxx的电商系统的工作量，特将属性系统做成通用版的。
设计思路如下：
1、可自定义的无限级商品类别。
2、各类别可自定义属性，属性的类型有：普通文本、数字、价格、单项选择、多项选择、日期、文本域、富文本、图片、布尔值等，添加商品时自动加载所需的组件。
3、支持公共属性。
4、支持属性继承，即子类别自动继承父类别的属性，并支持覆盖父类别同名属性。
5、支持属性值验证，添加商品时对必填项、正则表达式进行自动验证。
6、支持属性分组，添加商品时属性按照属性分组名进行分组。
模型设计：
Classify：商品类别表
Attribute：属性表
AttributeOption：属性选项表，只有类别为“单项选择”和“多项选择”时，属性需要设置属性选项。
Product：商品表
ProductAttribute：商品属性关系表
这里只是对商品属性进行了简单的建模，与属性无关的模型没有画出。
关键代码：

这种属性设计适用范围很广，几乎所有事物都可以使用属性来描述，比如新闻系统中的新闻，论坛中的帖子等等其实都可以用到。园子里有很多关于电商系统属性的设计，但几乎都只有模型。最近工作涉及到这一块，索性就将自己的设计思路与实现过程粗略的写出来，以供交流。
