网上购物电子商务网站的设计与实现

DesignandImplementationofE-CommerceSiteforOnlineShoppingDesignandImplementationofE-CommerceSiteforOnlineShoppingDesignandImplementationofE-CommerceSiteforOnlineShopping网上购物电子商务网站的设计与实现DesignandImplementationofElectronic-CommerceSiteforOnlineShopping. 购物系统网上购物系统（OSS）是基于HTML、CSS、JavaScript、百里香叶（前端）和Java、SpringBug、Hibernate、JPA和MySQL（后端）的一个基于Web的应用程序。为了实现OSS，购物系统不需要昂贵的硬件和软件，只需要互联网连接和桌面。该系统作为一个集中的数据库和应用程序，在线购物者可以方便地从任何地方基于注册凭证访问系统。OSS是一个独立的平台系统，几乎任何用户都可以访问，它使OSS易于使用、质量不断提高。网上购物是生活方式电子商务网络应用，零售各种女性生活方式产品（目前女性和卫生产品）。该项目允许查看各种产品，使注册用户立即使用PayPal支付处理器（即时支付）购买所需产品。本项目通过标准的可访问因特网系统向任何地方的管理员提供方便的访问。它也可以定制为个人在线购物者的需要。本文件将讨论创建和实现电子商务网站的每个基础技术。一种在线购物系统，它允许客户提交来自商店的物品和/或服务的在线订单，该商店同时为步行顾客和在线顾客提供服务。在线购物系统提供订单截止时间的在线显示以及客户所选商品的相关送货窗口。系统接受客户提交的购买订单，以响应在订单截止时间之前的提交时间。在线购物系统直到客户选择的商品从库存中挑选出来之后才与客户的信用供应商结算，但在交付之前。因此，客户可以在线更改订单。此外，可用服务窗口是根据客户选择的订单和服务类型向客户提供的函数，并且根据拣货者的喜好分配拣货任务。在订购商品时，许多购物系统提供一个虚拟购物车，用于存放选购的物品。选择购买的连续项目被放入虚拟购物车中，直到客户完成他们的购物之旅。虚拟购物车可以随时检查，其内容可由客户选择编辑或删除。一旦客户决定提交订单，客户就可以打印虚拟购物篮的内容，以便获得交易的硬拷贝记录。关键词：网上购物系统；JAVA；SQL；数据库；SPRINGBOOT；Html；CSS；JAVA脚本；百里香叶；HIBENATE；
