私信源码获取及调试交流

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb的SSM幼儿园信息管理系统(java+ssm+jsp+jquery+mysql)

项目介绍

本项目为后管系统，

管理员角色包含以下功能：

管理员登录,修改个人资料和密码,管理员用户管理,教师管理,家长管理,幼儿信息管理,上课管理等功能。

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：否；

技术栈

后端：Spring+SpringMVC+Mybatis 2. 前端：JSP+jQuery

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spring-mvc.xml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localhost:8080/ssm_youeryuan_info_sys/ 登录
