关于java:Spring-Boot-蓝天幼儿园管理系统拿来练手真不错

我的项目介绍

蓝天幼儿园管理系统，共分为三种角色：

管理员
家长
老师

管理员角色具备性能：

系统管理：用户治理、页面治理、角色治理
校园治理：老师治理、工资管理、物资治理、菜谱治理、班级治理
班级治理：学生治理、布告治理、课程管理
考勤治理：老师考勤、学生考勤、老师考勤统计、学生考勤统计、签到签退

技术栈

1、Springboot

Spring Boot 根底就不介绍了，举荐下这个实战教程：https://github.com/javastacks...

2、html+thymeleaf

环境须要

运行环境：最好是java jdk 1.8，咱们在这个平台上运行的。其余版本实践上也能够。
IDE环境：IDEA，Eclipse,Myeclipse都能够。举荐IDEA;
tomcat环境：Tomcat 7.x,8.x,9.x版本均可
硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
是否Maven我的项目: 是；查看源码目录中是否蕴含pom.xml；若蕴含，则为maven我的项目，否则为非maven我的项目
数据库：MySql 8.0版本；

应用阐明

应用Navicat或者其它工具，在mysql中创立对应名称的数据库，并导入我的项目的sql文件；
将我的项目中yml配置文件中的数据库配置改为本人的配置
应用IDEA/Eclipse/MyEclipse导入我的项目，Eclipse/MyEclipse导入时，若为maven我的项目请抉择maven;若为maven我的项目，导入胜利后请执行maven clean;maven install命令，
运行我的项目，输出localhost:8081 登录
