目录
一、项目介绍
前后端分离实现
- 项目分为三个部分：springboot后端、管理后台和用户平台pc端；
- 后端采用springboot+redis+mybatisplus+mysql+JWT token；
- 管理后台采用vue+elementui，用户平台端同样，框架类似，很好的框架、适合新手、老手，都可以，没有复杂错乱的结构。
二、项目截图
管理后台
1.登录（默认管理员账号密码均为：admin）
2. 用户管理
分为学生管理、教师管理，同表设计，界面差不多
3.任务管理
互助单（学生发布）
行政单（教师发布）
审核（退回需要写明原因）
4.管理员管理
5.个人信息、修改密码
用户端
1.登录
2.首页
可以对任务进行接取，搜索任务等
可评论
3.任务发布
互助单发布
行政单差发布
4.个人中心
5.我的发布
6.我的接取
7.消息中心
各种实时消息通知
三、 项目实现简述
1.项目需求、要求文档
2.后端项目
