基于Android的大学学生请销假管理系统app
博主介绍：本人专注于Android/java/数据库/微信小程序技术领域的开发，以及有好几年的计算机毕业设计方面的实战开发经验和技术积累；尤其是在安卓（Android）的app的开发和微信小程序的开发，很是熟悉和了解；本人也是多年的Android开发人员；希望我发布的此篇文件可以帮助到您；
文章末尾获取源码下载方式
功能演示
详情演示视频可以咨询后面的公众号；
1：后台演示
2：客户端演示
一、项目介绍
下拉列表选择,同步到个人主页(院系、专业)
一、注册登录:
1：学生端用"规定学号样式"注册()，2：选择"院系",“专业",“班级”1.2登录页面logo，
3：首页轮播图片
4：提供部份logo，图片，其余可根据需要自行安排
二、请销假1：学生能够实现请假、销假申请，以及筛选条件查看请销假详情（请假附件可添加图片，文件)
2：教师端可实时接收处理,并分类统计
三、拓展页面(应用)
1：查看已办或待办事件
2：可给自己添加日程安排（提醒)
3：学校新闻
(直接跳转到学校官网页面, https://www.jzci.edu.cn/)
四、设置页面
个人信息：用户登录之后可以查看用户的基本资料以及对密码信息进行修改
二、运行环境
1：客户端使用Android stuido进行开发；
2：服务端后台使用Myeclipse2014进行开发；
3：mysql数据库进行数据存储；
4：需要jdk1.7以上
5：使用雷电模拟器或者Androidstuio自带的模拟器进行运行
三、使用技术
总体设计逻辑和思路：
1：先设计数据库表文件
2：写服务端jsp页面以及写api接口给客户端提供数据
3：完成后台服务端的数据交互，也就是jsp页面数据的存储和显示
4：进行客户端页面的开发；
5：进行客户端对api接口的调用，也就是获取数据库的数据以及在客户端进行显示移动端：
1：使用android原生控件以及xml布局文件来完成界面的显示
2：使用java代码完成功能的数据和逻辑交互
3：使用http网络请求完成数据的请求；
4：使用json数据解析完成客户端数据的回调和显示服务端后台：
1：使用mysql完成数据的存储
2：使用jdbc完成数据库和代码的逻辑交互
3：使用jsp完成网页数据的显示
4：使用java代码完成api接口的编写以及以及数据的回调
四、数据库设计
