项目介绍
本系统分为两个角色，一个管理员，一个是护工；
管理员角色主要功能如下：
密码信息管理、系统用户管理(系统用户管理、增加系统用户、系统用户查询)、老人信息管理(老人信息管理、增加老人信息、老人信息查询)、事故记录管理(事故记录管理、增加事故记录、事故记录查询)、请假信息管理(请假信息管理、增加请假信息、请假信息查询)、床位分配管理(床位分配管理、)、入住费用管理、护工薪资管理、护工请假管理
护工角色主要功能如下：
密码信息管理、老人信息查看、请假信息查看、护工薪资查看等；
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；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
技术栈
1. 后端：servlet
2. 前端：JSP+css+javascript+bootstrap+jQuery
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，然后运行；
3. 将项目中util/DBO.java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/yanglaoyuan 登录
管理员账号密码：admin/111
护工账号密码：111/111
