    项目介绍

    本项目为后台管理系统,包括管理员、教师、家长三种角色；
    管理员角色包含以下功能：
    学生信息管理：学生列表、班级列表；
    生活展示：运动会、生活照、菜单；
    教师信息管理：教师列表；
    园所管理：园所信息；
    留言板：留言管理；
    系统管理：修改密码；

    教师角色包含以下功能：
    学生信息管理：学生列表、班级列表；
    生活展示：运动会、生活照、菜单；
    教师信息管理：教师列表；
    园所管理：园所信息；
    留言板：留言管理；
    系统管理：修改密码；

    家长角色包含以下功能：
    学生信息管理：学生列表、班级列表；
    生活展示：运动会、生活照、菜单；
    教师信息管理：教师列表；
    园所管理：园所信息；
    留言板：留言管理；
    系统管理：修改密码；
     

    管理员、教师、家长包含相同的菜单，但对应的权限各不相同，如教师只能查看和修改自己负责班级的学生等；

    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: 否；

    技术栈

    1. 后端：Servlet

    2. 前端：JSP+CSS+Javascript+jQuery+easyui+h-ui

    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util/DbUtil.java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/ 登录
