OA办公管理系统，这是一款由JSP+SSM（spring+springmvc+mybatis）+MySQL实现的简单的OA办公管理系统， 主要实现的功能有员工注册登录，自动计算当前月迟到、早退、加班、缺勤天数并根据图表展示， 任务管理（任务发布、更新、删除、进度条展示完成度），通知管理（通知发布、更新、删除）， 站内信发布、回复、删除等，发布公告和任务及站内信时可上传图片等。
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：Spring+SpringMVC+Mybatis 2. 前端：JSP+CSS+JavaScript
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; 3. 将项目中db.properties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/OAManagerSys 登录 注意：路径必须为/OAManagerSys,否则会有图片加载不出来 管理员账号/密码：admin/admin 账号/密码：zhangtao/123
