基于J2EE技术的网上考试系统的开发与设计.doc

北京科技大学天津学院本科生毕业设计（论文）本科生毕业设计(论文)-1-基于J2EE技术的网上考试系统的开发与设计摘　　要在网络技术逐渐渗入社会生活各个层面的今天，传统的考试方式也面临着变革，而网络考试则是一个很重要的方向基于网络的考试系统是传统考场的延伸，加上数据库技术的利用，大大简化了传统考试的过程因此网络考试系统是电子化教学不可缺少的一个重要环节所以现在较好的考试方法为网络考试，考生通过姓名、准考证号码或口令进行登录，试卷可以根据题库中的内容即时生成，可避免考试前的压题；而且可以采用大量标准化试题，从而使用计算机判卷，大大提高阅卷效率；还可以直接把成绩送到数据库中，进行统计、排序等操作因此，采用网络考试方式将是以后考试发展的趋势网络考试系统的实现技术有多种，我们开发制作的网络考试系统是采用典型的浏览器/服务器型的b/s架构，系统按照功能的分类划分为相对独立但又相关的两大部分，其开发主要包括考生考试应用程序的开发、服务器考试管理系统应用程序的开发本考试系统以Windows XP操作系统、MySQL为数据库平台，开发工具为MyEclipse 6.5MyEclipse 6.5是非常流行的基于java语言的可视化编程工具，MySQL 是一个小型关系型数据库管理系统。

首先建立考试系统应用程序框架,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成满意的可行系统在开发过程中遵循了软件工程原理，经历了需求分析、概要设计、详细设计、测试与配置几个阶段，直至后期的系统维护，从而保证了软件的质量论文内容共分六部分：第一部分是引言，简要介绍了网络考试系统，开发工具的选择；第二部分是网络考试系统功能分析与应用程序框架的建立，确定了系统的确切需求同时建立考试管理系统应用程序框架；第三部分是考试管理系统概要设计，将服务器考试管理系统按照功能的分类划分为相对独立但又相关的五大功能模块，并在此基础上逐步细化；第四部分是考试管理系统详细设计；第五部分是测试与调试；第六部分是致谢页The network examination system realized by J2EE techniqueAbstract Seep into today that society life of each level gradually in the network technique, the traditional examination method also faces to replace, and network examination is a very important direction. According to the examination system of the network is process that the exploitation that the tradition tests a field extensions. With the Technique of database, simplifying the tradition examination consumedly. For this reason network examination system is an important link of the electronical teaching indispensability. So the good examination in now method examines for the network, the examinee passes the name and allow to research number or passwords proceed the logging, for a contents according to a real time born, can avoiding the examination press; And can adopt large quantity standardize to try, from but the usage calculator judges book, increases to grade examination papers the efficiency consumedly; Can also send to the score directly in the database, proceed the covariance, row preface etc. operation. Therefore, adoption network examination the way will examine the trend of the development later on.The network examination system realizes technique contain variety, we develops the network examination system of the creation is development and examination backup system that the classification that the type of b/s to adopts typical browser/ server type configurings, the system divides the line according to the function to apply the procedure for opposite independence but again related two greatest molds a development, server for, its development primarily including users examination applying procedure examination control systems apply the development of the procedure. This examination system regard the operate system of WindowsXP,MySQL as the database terrace, the development tool is MyEclipse 6.5. MyEclipse 6.5 is very popular of according to the Java is phonetic to see to turn to weave the distance tool, the MySQL is a table's top relation database management system.  First establish the examine system application procedure frame, then, start to the beginning the prototype system proceeds to require on behalf, revising continuously with improve, until formation satisfied can a system. Followed the software engineering principle in develop process, experience the need analysis, essentials design, detailed design, test with install a few stages, keep to the in the late system to support, from but guaranteed the quantity of the software.The thesis contents is divided into totally six part: The first part is choice that preface that server examination management system, the synopsis introduced the network the examination the system, developping the tool; The second part is a network examination system function analysis and apply the procedure frame establish, making sure the system to really slice the need to establish at the same time examination control system application procedure frame; The third part is classification that examination management the system essentials designs, examining the server to control the system to divide the line according to the function for opposite independent but again related five greatest functions mold piece, and here foundation top gradually thin turn; The four-part cent is a detailed design in system in management in examination; The fifth the part is a test with install; The sixth part is the page with gratitude.目　　录摘　　要 1Abstract 2引 言 61需求分析 71.1系统目标 71.2可行性分析 71.2.1现有的数据库程序的分层结构 71.2.1.1 传统二层结构 71.2.1.2 网络分布式应用系统 71.2.2 XML语言 81.3 本系统的选择方案 91.4 建模工具的选择 92 基于UML的系统分析 102.1用例图 102.1.1 用户关系图 102.1.2 系统用例图 102.2 顺序图 112.2.1 老师活动顺序图 112.2.2考生活动顺序图 122.3 类图 133 数据库的分析设计 143.1 图 143.2 表设计 143.2.1 用户表设计 143.2.2 课程表设计 153.2.3 试题表设计 153.2.4 试卷表设计 163.2.5 成绩表设计 163.2.6 试卷试题表 174 系统实现 184.1 开发平台的选择 184.2 编辑工具的选择 184.3 系统编码 184.3.1 核心配置文件web.xml 184.3.2 Spring配置文件applicationContent.xml 204.3.3 struts2.0配置文件struts.xml 254.3.4 DWR配置文件dwr.xml 29。
