近年来互联网购物的普及使得人们对网上购物变得更加热衷。传统购物方式受其价格、种类等因素限制，不能满足当下用户新形势的购物要求，而网上书店借由互联网或移动设备的普及以其轻便、及时等友好特性，受到广大购物者的追捧。因此，一个好的网上书店可以带给人们更多的选择。
本次采用B/S架构实现系统工程开发，系统架构采用时下流行的SpringMVC框架为服务端Web程序，为整个系统提供逻辑业务处理服务和主要算法支持，SpringMVC在数据持久层整合Mybatis框架映射数据库，为系统开发提供简单直接的数据处理操作。网上书店系统的前端页面使用了JSP技术，这是一个和HTML相似网页视图。JSP技术是开发Web应用程序的常用视图技术，它拥有Java语言跨平台的特性，以及业务代码分离、组件重用、基础Java Servlet功能和预编译等特征。数据库采用Mysql，数据库开发中使用了PowerDesigner进行数据库设计。各功能运行正常，基本能实现需求分析中的主要需求。

The popularity of Internet shopping in recent years has made people more enthusiastic about online shopping. The traditional way of shopping is limited by its price，type and other factors，which cannot meet the shopping requirements of the new situation of users at present，and the online bookstore borrows from the Internet or the popularity of mobile devices with its portable，timely and other friendly characteristics，and is sought after by the majority of shoppers. Therefore，a good online bookstore can bring people more choices.
Using the B/S architecture to implement the system engineering development，the system architecture uses the popular Spring MVC framework for the server-side Web program，providing logical business processing services and main algorithm support for the whole system，and the Spring MVC integrates the Mybatis framework mapping database in the data persistence layer to provide simple and direct data processing operation for the system development. The front page of the online bookstore system uses JSP technology，which is a page view similar to HTML. JSP technology is a common view technology for the development of Web applications，it has Java language cross-platform features，and features such as business code separation，component reuse，underlying JavaServlet functionality，and pre-editing. The database adopts Mysql，and Power Designer is used for database design in database development. Each function runs normally，basically can realize the main demand in the demand analysis.
