基于javaweb的养老院管理系统(java+ssm+bootstrap+jsp+mysql)

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb+SSM的养老院管理系统(java+SSM+BootStrap+jsp+Maven+mysql)

养老院管理系统

该系统主要功能室养老院系统，采用mvc三层架构

1、采用技术书spring、springmvc、mybatis、maven等技术 2、数据库是mysql,共11张表 3、前端使用bootstrap架构 4、本系统提供两个角色，管理员和普通护理人员，在登录时会进行角色管理，不同角色看到内容不同 5、用户管理包括用户的展示、查询、新增、删除、分页等功能 6、老人管理包括老人信息详情、查询、联系人、事故、护理等级、修改、删除、新增等功能 7、房间管理包括房间详情、查询、修改、删除、新增，支持多个同时删除 8、工资管理主要功能室对员工工资的管理 9、请假管理是管理员工的请假天数、扣除工资等 10、护理等级包括老人和护理人员配对管理

11、工资统计是对工作人员工资管理

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.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：MySql 5.7版本；

技术栈

后端：Spring SpringMVC MyBatis 2. 前端：JSP+bootstrap+jQuery

使用说明

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. 将项目中applicationContext.xml配置文件中的数据库配置改为自己的配置;
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，配置tomcat，然后运行；

运行项目，输入localhost:8080/xxx 登录
