———简易网上书店系统的设计与实现
摘要
本文设计一个简易的电子商务系统——网上书店的设计与实现,以使每一位顾客不用出门在家里就能够通过上网来轻松购书。系统采用界面与业务逻辑分离的三层结构设计,使系统的安全性,可维护性,重用性和可扩展性都大大提高。首先介绍了课题所涉及的相关技术:多层用户/服务器结构以及Web应用的相关数据库访问技术,JSP技术。STRUTS框架以及使用方法。本系统的特色之一在于应用了STRUTS框架技术,而没有采用传统的JSP+JAVABEAN+后台数据库的形式编程,在加入了STRUTS框架后,M(model) V(view) C(controler) 系统的各个层次闲得更加清晰,在JSP页面上大大的减少了JAVA的代码量,使JAVA代码全部在页面上消失,使其烦琐的业务逻辑全部转移到了中间层,由控制层C(controler)去实现这一功能。从而提高了系统的可读性和可维护性。在此基础上论述了网上书店系统的设计目标、系统需求和总体设计方案,功能上的完备,面向对象的三层结构设计,模块化的界面设计是本文章所引用的特点。从而较详细的论述了网上书店系统的详细设计和实现。
关键词:JSP,STRUTS框架,网上书店系统。
Abstract
The paper designs a simple e- commerce system——on-line bookshop, which makes every customer can buy their books on the at home easily without getting out .The system adopts a three-tier architecture project where the interface is separated with professional logic, which could make great improvement on the security, the maintainability, the reusability and the expansibility of the system .Firstly the paper gives a introduction of several key techniques about the task : multi-tier Client/Server Architecture, Web-related technology , JSP(Java Server Page), STRUTS frame and using method. One of the feature of the system is STRUTS frame technique .The programme doesn’t adopt the traditional form of JSP+JAVABEAN+background database. With the STRUTS frame technique, every arrangement of M(model)V(view)C(controler)system es more distinct, the quantity of Java code in JSP page gets reduced, the Java code disappears in the page, it turns all of the intricate professional work to middle tier, with the function realized by controller, which improves the readability and the maintainability of the system. Based of them the paper discussed the design aim ,system requirements and general design scheme,maturity in function ,the three-tier architecture with OO, interface design of modularization are characteristic in this paper, it elaborates upon the details of design of the on-line bookshop system.
Key words:JSP,STRUTS,on-line bookshop.
