摘要:伴随着时代脚步的前进和信息技术的突飞猛进，信息时代已经到来。计算机技术和网络技术是信息时代的信息载体，它们将代替传统的信息载体被更多的应用于各行各业。而教育事业也随着科技的进步不断的发展，在面对人们日益增加的对教育的需求情况下，传统的教育和考试方式必将面临变革。在线网络考试是近年来考试变革的主要方向，逐渐各大院校应用代替传统考试。

　　　在线考试系统旨在实现考试的无纸化管理。它利用覆盖广泛的网络平台实现在线考试，不需要统一考场，考生无论在何地拥有网络就可进行考试。这种考试平台相对传统的大型考场更易于实现也更加灵活。在线考试由计算机随机抽取题库中的试题，避免了试卷的重复，对于考试作弊现象起到防范作用。计算机阅卷在减少人力消耗的同时避免了人工阅卷中出现的人为错误，提高了考试的质量。在线考试系统使考试更趋于公平、公正、客观，从而提高学生的学习兴趣。

　　　本论文主要介绍一个基于J2EE的中国近代史在线考试系统的系统结构与具体功能的代码实现。本系统主体框架采用Struts中的MVC三层体系结构模式进行设计，具体使用JSP+JavaBean+MySQL技术进行实现。系统前端的视图层由JSP页面实现，模型为系统中各种JavaBean，而Struts中的ActionServlet担任控制器的角色。后端使用MySQL数据库实现数据逻辑，通过jdbc与前端联系。

Abstract:Along with The footsteps of time to move forward and the information technology developments by leaps and bounds, information age has arrived. Computer technology and network technology is the information carrier of the information age, they will take the place of the traditional information carrier is more used in all walks of life. Career education is also in constant development , in the face of the people's growing demand for education, traditional education and examination mode is bound to face change. Online exam is test the main direction of change in recent years, universities gradually application instead of traditional test.

　　　Online examination system aims to achieve paperless management. It uses wide coverage of network platform to realize the online exam, don't need to unified exam, the examinee wherever have network test can be carried out on. This exam platform relative to the traditional large venue more easy to implement and more flexible. Computer grade examination papers in decreasing the consumption of manpower, and avoid the human error in manual marking, improve the quality of the exam. All of these to make the examination more tend to be fair, fair and objective, thus improving the students' interest in learning.

　　　This paper introduces a j2ee-based online examination system of modern Chinese history system structure and specific function code implementation. This system main body framework USES the Struts MVC three layer architecture model for design of concrete using JSP + JavaBean + MySQL technology implementation. System front-end view layer by JSP pages, model for the system in all kinds of javabeans, and Struts the ActionServlet in the role as controller. The back-end using MySQL database for data logic, contact the front through JDBC.
