vue医疗系统预约挂号demo

作者主页：编程千纸鹤

作者简介：Java、前端、Pythone开发多年，做过高程，项目经理，架构师

主要内容：Java项目开发、毕业设计开发、面试技术整理、最新技术分享

项目编号：BS-XCX-007

前言：

中国人口众多，医疗资源匮乏，人们就医难从建国开始就一直存在，如何使医疗资源能惠及大众，让老百姓们享受医疗资源更加的公平，也是政府管理者一直在思考解决的问题。解决公平问题，一是要靠制度，二是要靠技术。目前在医疗领域普遍应用的信息化技术手段，就可有效的辅助解决医疗资源有效利用的问题。比如目前医院一号难求的局面，如何更加公平的解决，从而遏制黄牛倒号党的产生，并且更加有利于群众挂号治病。在线预约挂号系统可以在这方面起到非常积极的作用，通过患者注册账号，一个身份证只能挂一个号，人证对照，接诊时必须是本人就诊才可以实现看病就医，一是方便群众在家就可以远程挂号预约时间，二是也可有效的解决就医公平问题。

一，项目简介

本项目基本UNI-APP前端框架开发，后台基于Springboot+Vue开发实现，完成了一个在线预约挂号系统，系统的使用角色有三个：管理员、患者、医生。

患者的主要功能：

  1. 注册登陆
  2. 查看资讯信息：对信息进行点赞、收藏、评论
  3. 查看医院的挂号大厅：可以对医生进行点赞评论，在线预约挂号
  4. 个人中心:管理个人信息，查看预约信息列表，取消预约信息，修改预约信息等操作

医生的主要功能：

  1. 登陆
  2. 查看资讯信息：对信息进行点赞、收藏、评论
  3. 查看医院的挂号大厅：可以对发布的挂号信息进行查看等
  4. 个人中心:管理个人信息，查看预约信息列表等操作

管理员的主要功能：

  1. 登陆系统
  2. 轮播图管理
  3. 公告信息管理
  4. 用户管理：管理员管理、普通用户管理、医生用户
  5. 内容管理：资讯信息管理、资读分类管理
  6. 挂号大厅：发布挂号信息
  7. 挂号信息查看及修改
  8. 查看己取消的挂号信息

二，环境介绍

语言环境：Java:  jdk1.8

数据库：Mysql: mysql5.7

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA、HbuilderX、微信开发者工具

开发技术：后台开发Springboot+Mybatis

前台开发：UNI-APP和微信小程序

五，项目总结

现在人们的生活节奏随着生活压力的增大越来越高，人们变得十分焦虑，不再有耐心等待。而计算机信息化技术有效应用，有效的解决人们对时空效率的要求，它的应用不断地渗入到各个邻域，比如像在医疗领域、教育方面等，信息化技术的使用确实给我们的生活带来很大的改变。比如就医疗领域方面来讲，以前我们很多医院就医生挂号大多都采用的是人工排队挂号的方式，这种方式不难浪费了患者的时间，也降低了就诊的效率，本就资源匮乏的医疗领域，则变的更加紧张，这不仅造成医院拥挤秩序混乱，更是拉动人力物力成本高。在线预约挂号系统则可以有效的解决这一问题，患者只需在家通过电脑访问挂号系统网站即可实现在线挂号，即方便患者，又节省医院资源，提高就诊效率，增加医院收入。
