Java 实战中精品养老院管理系统的实现流程是怎样的

这期内容当中小编将会给大家带来有关Java 实战中精品养老院管理系统的实现流程是怎样的，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

一、项目简述

本系统功能包括：通知公告，老人管理，护工管理，问答管理等等功能。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX（Webstorm也行）+ Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）。

项目技术：

Springboot + Maven + mybatis+ Vue 等等组成，B/S模式 + Maven管理等等。

系统控制器（登录、注销、修改、新增登）业务：
