摘要
随着计算机互联网的不断发展,学生考试的技术手段和载体发生了划时代的变化。计算机技术、网络技术和考试理论的日渐成熟,使考试从传统的纸笔考试到计算机辅助考试再发展到基于互联网的在线考试成为现实。基于互联网技术支持的在线考试系统就是借助遍布全球的因特网,考试既可在本地进行,也可在异地进行,大大拓展了考试的灵活性。而且智能组卷系统,自动阅卷评分和试卷分析将教师从繁重的工作中解脱出来,这大大提高了工作效率,真正的实现了无纸化考试。
本系统采用 Struts+JavaBean框架建立了一个比较完善的B/S模式的智能在线考试系统,本系统主要是为了能满足公司各个部门的标准化考试的功能需求,以求使得考试形式更具智能化、更具合理性。
在Struts框架中,模型分为两个部分:系统的内部状态和可以改变状态的操作(事务逻辑)。内部状态通常由一组 ActionForm JavaBean表示。根据设计或应用程序复杂度的不同,这些Bean可以是自包含的并具有持续的状态,或只在需要时才获得数据。用DAO设计模式封装数据,使得系统结构清晰,数据库操作与业务逻辑各自独立,也利于系统功能的扩展。

The development Of A Online Examination System Based On J2EE
Abstract
With the continuous development of the , students examination techniques and vector epoch-making changes have taken place. Computer technology, network technology and the maturing of the theory examination in order that the examination from the traditional pen and paper exams puter-aided re-examination of the development of -based online exam to e a reality. -based technical support is to make use of online examination system of the around the world, the examination can be conducted locally and can also be carried out in different places, greatly expanding the flexibility of the exam. Paper and intelligent system, automatic scoring and test score analysis will be teaching from the heavy work greatly enhanced the efficiency of the realization of a truly paperless examination.
The system uses a Struts + JavaBean framework for the establishment of a plete B / S mode smart online examination system, the system is mainly in order to meet the departments of pany’ all the functions of the standardized test requirements, in order to make exam form of more intelligent, more reasonable.
In the Struts framework, the model is divided into two parts: the system's internal state and can change the state of operations (business logic). Internal state by a group of normally expressed ActionForm JavaB
