篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JavaWeb课程设计——基于Jsp+Servlet+MySQL的科研申报系统课程设计相关的知识，希望对你有一定的参考价值。
项目类型：JAVA WEB项目
项目名称：基于Jsp+Servlet的教师科研成果申报系统
用户类型：3个角色（管理员+教师+审批人）
系统类型：后台管理系统
设计模式：jsp+Servlet+MVC
开发工具：Eclipse/Idea均可以导入使用
数据库：mysql+Navicat
数据库表：4张
适用：软件工程、计算机科学与技术等JAVA课程的学习和实验
PS:本系统基于web环境，在开发语言方面，由于Java的可移植性好，可在各个操作系统之间进行无障碍的转换，具有多操作系统性，因而选择Java作为本系统的开发语言。本系统的开发过程与一般的软件开发类似，先进行系统的需求分析，再对系统进行总体设计，之后划分模块，最后再对每个单独的模块进行编码与开发。而这一系列的设计过程都与一般的系统设计相同。并且Idea和Eclipse均可以使用
