Java项目:课程在线学习与测试系统(java+SSM+redis+Bootstrap+Tomcat+mysql)

源码获取：博客首页 "资源" 里下载！

基于B/S架构的课程在线学习与测试系统

启动说明

项目为maven管理，最近集成了redis，所以在运行项目是先要下载redis并启动客户端，方可正常运行项目，由于只需要下载redis，无需其他配置，这里就不做过多说明。

项目采用前后端分离技术实现

***

- 框架：SSM（Spring，SpringMVC，Mybatis）

- 缓存：redis

- 数据库：MySQL

- IDE：Intellij IDEA/Eclipse

- 其他：Maven，Git

项目亮点

***

1. 前后端分离。

1. 用户登录权限区分和控制。

1. 防止横向越权和纵向越权。

1. 密码MD5明文加密。

1. 设计高复用的服务器响应对象。

1. guava缓存。

1. pojo，vo抽象模型。

1. 数据绑定对象。

1. Mybatis分页

1. Bootstrap。

1. artTemplate，artDialog，iframe前端模板使用。

1. select2、toastr、sweetalert等等前端插件的使用。

1. redis缓存。

1. 全局异常处理，拦截器权限统一检验。
