基于Java的高校毕业设计选题管理系统
摘 要
随着科技科技快速发展,信息技术已经出现在我们生活中的各个角落,计算机网络的规模也飞速扩大,可以应用的领域也越来越多。在网络上可以进行商业活动,也可以进行日常的通信交流。网络与我们的生活息息相关。
但是在很多高校中,毕业设计选题这个每个大学生都要经过的过程,只能通过手动填写表格并上报的方式来选择想要的毕设题目,既不方便学生选题,也不方便老师管理。费事费力,效果还不尽如人意。由此现状,诞生了此次项目的需求前提。
本次项目为基于Java的高校毕业设计选题管理系统,可以让学生在此系统中直接选报自己想要的题目,老师也可以通过此系统来发布题目。学生可以操作的功能包括:选择课题、修改选择的课题、退选课题,修改个人信息及其密码;教师可以操作的功能包括:添加课题、修改已有课题、删除课题、修改个人信息及其密码;管理员可以操作的功能包括:添加教师、批量添加教师、添加学生、批量添加学生、管理课题、维护系统。
本次项目的开发环境是Eclipse,服务器采用Tomcat,前台页面主要以JSP为主,嵌套较少的JavaScript语句以及CSS样式,后台数据库利用了现在非常流行并且是免费开源的MySQL数据库,采用B/S结构,整个系统采用三层架构模式。所有技术均为免费开源。

Graduation project management system
Abstract
With the rapid development of science and technology, information technology has appeared in every corner of our lives, the rapid expansion of the scale of computer networks, the field can be applied more and more. On the network can carry on the commercial activity, also may carry on the daily communication exchange. The Internet is closely related to our life.
But in many universities, the graduation design topic for each of the students to go through the process, only by manually fill in the form and report the way to select the desired complete set of questions, neither convenient nor convenient students topics, teacher management. Trouble and effort, the effect is not satisfactory. Thus the status quo, the birth of the project requirements premise.
The project for the university graduate design topics management system, allowing students to choose their own direct reporting system in this topic, the teacher can also issue a title through this system. Students can operate the function includes: the selection of topics, modify the selected topic, topic selection, modify personal information and password; teachers can operate functions include: add topics, topic, topic, modify delete and modify personal information and password; administrator can be operation function includes: adding teachers, teachers, batch add add students, students, batch add management issues, maintenance system.
The project development environment is Eclipse, using Tomcat server, the front page is dominated by JSP, the less nested JavaScript statements and CSS style, the backstage database uses MySQL, using B/S structure, the system adopts three layer architecture. All technologies are free open source.
Keywords: Graduation project, java, JSP, B/S structure, three layer architecture
