项目介绍

基于SSM的在线视频教育网站系统设计与实现.系统分为管理员与普通用户两种角色。

1)登录模块

在进入系统首页后，首先看到的是登录界面，该界面会提供注册用户的功能，在登陆界面，输入用户名之后，首先要发送ajax请求验证用户名是否存在，第一时间内给用户提示。

2)客户端模块

本模块分为密钥管理，角色管理，权限管理，个人信息，课程信息等组成。

3)后台管理模块

本模块包括用户管理，作品信息管理等。用户管理：提供管理员查询用户，锁定解锁用户，修改用户信息，充值余额。课程信息管理：提供管理员增加删除修改功能。系统日志查看：查看所有系统的动作信息。访问ip管理：提供对访问IP的管理，可以进行拉黑IP等操作。

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. 后端：SSM(Spring SpringMVC MyBatis)

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，配置tomcat，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/xx 登录; xx为项目路径；

后台访问地址：localhost:8080/xx/admin
