Java项目:学生信息管理系统(java+Servlet+Jsp+easyui+Mysql)

源码获取：俺的博客首页 "资源" 里下载！

介绍

学生信息管理系统,该项目分为管理员、老师、学生三种角色；
管理员主要功能：
学生信息管理、班级信息管理、教师信息管理、系统管理；
老师主要功能：
学生信息管理、班级信息管理、教师信息管理、系统管理；
学生主要功能：
学生信息管理、系统管理；

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.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目 
6.数据库：MySql 5.7版本；

技术栈

1. Servlet+Jsp+easyui

使用说明

1. 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，配置tomcat，然后运行；
2. 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；
3. 将项目中DbUtil.java中的数据库配置改为自己的配置
4. 配置tomcat,运行项目，在浏览器中输入localhost:8080/xxx 登录
5.管理员账号：admin 密码：admin
教师账号：王鹤翔老师 密码：111
学生账号：江小雷 密码：1
