　　　　　　　基于JSP的网上拍卖系统的分析与设计 PAGE 毕业设计 基于JSP的网上拍卖系统的分析与设计 摘要 随着Internet的日益普及和电子商务的发展,网上拍卖迅速成为一种非常活跃的C2C电子商务模式。文中详细介绍了JSP技术以及分析了基于JSP建立网上拍卖系统的技术手段，深入探讨了如何利用JavaBean技术实现与SQL Server 2000数据库连接的方法。 系统采用界面与业务逻辑分离的三层结构设计，将页面显示交由JSP控制，把业务逻辑封装在JavaBean中，提高了系统的安全性、可维护性、重用性和可扩展性。 系统的注册模块应用了AJAX技术，不但实现了无刷新提交数据而且减轻了服务器的负担;通过缓存系统配置信息减轻数据库服务器的压力;对系统后台模块使用双重密码校验和验证码技术，进一步提升了系统的完全系数，使它能即使在复杂的网络环境也能以最小的系统开销正常运行。 关键词：电子商务，C2C， JavaBean，AJAX ABSTRACT With the increasing popularization of Internet and the development of electronic commerce, the net auction quickly becomes one kind of active C2C electronic commerce. The article detailedly introduces a JSP technique and analyzes the technique means of building a net auction system based on JSP, then deeply discusses how to use JavaBean technique to build connection with SQL Server 2000 databases. The system uses three structural designs which the contact surface and the service logic separates, the page demonstrated hands over by the JSP control, the service logic seal in JavaBean, enhanced the system security, the maintainability, has entrusted with heavy responsibility the nature and may the extension. The system registration module has applied the AJAX technology, not only realized to not renovates submits the data moreover but lighten the server burden; It has reduced the database server through the buffer system disposition information the pressure; The systerm uses dual password verification and the confirmation code technology in the system backstage module, has further promoted the system complete coefficient, and enables it work by the smallest system expenses normal operation in the complex network environment. Key words: Electronic Commerce，C2C，JavaBean，AJAX 目录 TOC \o 1-3 \h \z \u 第一章 绪论 h 1 1.1 系统应用背景与功能 h 1 1.2 系统预览 h 2 1.3 系统特点 h 2 第二章 系统要解决的技术问题 h 4 2.1 连接SQL Server 2000 h 4 2.2 安装jspSmartUpload文件上传组件 h 4 2.3 JSP中文乱码问题的处理 h 5 2.4　页面无刷新地提交数据 h 6 第三章 系统设计 h 8 3.1 系统
