功能说明

基于javaweb+mysql的SSM+Maven大学生创新项目管理系统(java+ssm+bootstrap+jsp+mysql)

项目介绍

本项目包含管理员、学生、专家三种角色；管理员角色包含以下功能：管理员登录,学院管理,专业管理,班级管理,用户管理,创新计划查看,查看项目申请,项目申请审核等功能。

学生角色包含以下功能：学生登录,查看创新计划,申请和查看我的项目,创新创业计划书填写等功能。

专家角色包含以下功能：专家登录,查看创新计划,申请项目,学生项目列表,管理预算记录等功能。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。 2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA; 3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可 4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 5.数据库：MySql 5.7版本； 6.是否Maven项目：是；

技术栈

后端：Spring+SpringMVC+Mybatis 2. 前端：JSP+CSS+JavaScript+jQuery+bootstrap

使用说明

使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven; 若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行； 3. 将项目中jdbc.properties配置文件中的数据库配置改为自己的配置; 4. 运行项目，在浏览器中输入http://localhost:8080/ssm_schoolproject_sys 登录
