基于javaweb+mysql的springboot宿舍管理系统(java+springboot+thymeleaf+html+layui+mysql)

运行环境

Java≥8、MySQL≥5.7

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+mysql的SpringBoot宿舍管理系统(java+springboot+thymeleaf+html+layui+mysql)

项目介绍

宿舍管理系统,分为系统管理员与学生两种角色； 系统管理员主要功能包括： 系统管理：用户列表、角色与权限； 学生管理：学生列表、教学班级； 宿舍管理：寝室列表、寝室类型； 入住管理：住宿申请、宿舍分配详情； 学生主要功能包括：

申请入住、个人信息管理；

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

(1)Spring Boot v2.3.1 (2)Spring Data JPA 的 hibernate实现 (3)shiro 用于授权与认证 (4)Thymeleaf+html 服务器端模板引擎 (5)layui 布局前端界面

(6)jQuery 简化Dom操作与Ajax请求

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，配置tomcat，然后运行； 3. 将项目中application.yml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 5. 管理员账户：admin 密码：123

学生账户：0123 密码：123
