基于JSP的毕业设计选题系统的设计与实现

摘 要

随着全球信息化技术的兴起，特别是Internet的日益普及，我国各大中专院校都建立了自己的校园网。毕业生以班级为单位的原始手工报送的选题方式已经不能适应时代发展的需求， 所以基与互联网的毕业设计选题系统也就孕育而生了。

毕业设计选题系统就是能够使学生通过互联网完成毕业设计课题的选定，它采用Web方式，同时适用于局域网和Internet，它要实现审核，权限管理，邮件通知等功能，并能提供题目保存、题目查询等功能,该系统同时拥有最开放的题库管理系统和最灵活的选题系统，能够自动进行权限的判断，对用户进行冻结。

我们采用了JSP技术为主要手段,本系统采用了多级角色管理：包括系统管理员、系主任，学生和老师几种权限.本文主要介绍了用户权限的划分，并详细地论述了系统设计的思想和实现的方法步骤从而为以后的研究打下了基础。

The Design and Implementation of Subject Selection

System for Graduation Based on JSP

Abstract

With the rising of global information technology, especially the growing prevalence of Internet, the technical institute colleges and universities in our country have set up their own Campus Net. For the traditional way of manual submission of selected subject cannot adapt to current demands, the Internet-based graduation subject selection system born.

Such system enables students to choose subject for graduation design through Internet. It adopts B/S pattern, and is suitable to both the local area network and Internet. It must implement functions such as the verification of the subject, the jurisdiction management, mail notification, as well as subject storage and searching. With the open subject management system and the flexible system, it can automatically verify the jurisdiction of a user and freeze the user. The system adopted the JSP as its main technology, and implemented the multistage role management. The system also implemented the management of the privilege of system managers, deans, students and teachers.

Key words: Verification; Jurisdiction; Multistage role management.
