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。

Design and Application of Selected Topic 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 sending the selected graduates to the unit cannot adapt to the demands of the time, the Internet –based graduation system of selecting topic born.
The selection system enables students to complete the choice of topic on graduation design by Internet. This system adopts Web, and be suited to the local area network and Internet. It must realize the verification, the jurisdiction management, mail notice etc. and can store and search for topics. With the most open topic management system and the most flexible elected topic system, it can automatically judge the jurisdiction and freeze the user .
As we have used the JSP technology as a main method, the multistage role management has been adopted in this system, including the jurisdiction in the possession of system managers, deans, students and teachers. This paper mainly introduces the users’ jurisdiction division and elaborates the idea of system design and the methods and steps of realization, laying a solid foundation on further research.
Key words: Verification; Jurisdiction; Multistage role management.
