    项目介绍

    管理员操作包含以下功能：
    管理员登录,学生管理,成绩管理,教师信息管理,课程信息管理,学院管理,专业管理,班级信息管理,用户管理等功能。

    由于本程序规模不大，可供课程设计，毕业设计学习演示之用

    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

    1. 后端：Spring+SpringMVC+Mybatis

    2. 前端：JSP+CSS+JavaScript+jquery+easyUI

    使用说明

    1. 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-druid-config.properties配置文件中的数据库配置改为自己的配置;

    4. 运行项目，输入http://localhost:8080/ssm_sims 登录

    管理员账号/密码：admin/admin
