项目介绍

系统描述： OA办公管理系统，这是一款由jsp+ssm（spring+s pringmvc+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。

运行环境：jdk1.8 eclipse tomcat7 mysql5.7

运用技术：jsp+ssm（spring+s pringmvc+mybatis）+mysql

环境要求

1.运行环境：最好是java jdk1.8,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：Tomcat7.x,8.X,9.x版本均可

4.硬件环境：windows7/8/10 4G内存以上；或者Mac OS;

5.是否Maven项目：是；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：MySql5.7/8.0等版本均可；

技术栈

后台框架：ssm、MyBatis

数据库：MySQL

环境：JDK8、TOMCAT、IDEA

使用说明

1.使用Navicati或者其它工具，在mysql中创建对应sq文件名称的数据库，并导入项目的sql文件；

2.使用IDEA/Eclipse/MyEclipse导入项目，修改配置，运行项目；

3.将项目中config-propertiesi配置文件中的数据库配置改为自己的配置，然后运行；
