    项目介绍

    本项目有多种角色,包含管理员、用户、护士、服务前台等角色。由于篇幅限制,只截图了管理员角色的功能。

    管理员角色主要功能包括:

    入院,出院管理,医生管理,药品管理,结算中心,用户管理,日志管理等的功能。

    用户角色主要功能如下:

    结算中心:缴费记录、费用查询;
    护理中心:录入体征数据、体征数据查询、住院历史、用药历史;

    护士角色主要功能如下:
    入院管理:住院查询;
    出院管理:出院查询;
    结算中心:缴费记录、费用查询;
    护理中心:录入体征数据、体征数据查询、用药历史;
    统计中心:病人统计、病房统计;
    药品管理:药品发放;

    服务前台角色主要功能如下:
    入院管理:入院登记、住院查询;
    出院管理:出院登记、出院查询、转院/病房;
    结算中心:费用预缴、缴费记录、费用查询;
    统计中心:病人统计、病房统计;
    药品管理:库存查询;

    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+jquery+bootstrap

    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/ 登录
