毕业设计-基于Springboot实现公租房申请管理系统

作者简介：Java领域优质创作者、CSDN博客专家 、掘金特邀作者、多年架构师设计经验、腾讯课堂常驻讲师

主要内容：Java项目、毕业设计、简历模板、学习资料、面试题库、技术互助

文末获取源码 

项目编号：BS-XX-120

一，项目简介

本项目基于Springboot开发实现了一个公租房申请管理系统平台，系统分为管理员用户和公租房申请用户。管理员用户又分为三种：超级管理员，基础数据管理员，审核管理员。超级管理员主要用来管理管理员和普通用户信息，资讯信息等，基础数据管理员主要用来管理小区，房屋等相关信息，审核管理员主要用来审核用户的申请信息，给用户进行配租等。前端用户在前台界面可以查看公租房申请的相关政策信息，相关流程，实现在线注册和登陆，并可以在线申请公租房。

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或eclipse

后台开发技术：springboot+mybatis

前台开发技术：layui+jquery

特点技术：短信发送，GoEasy通信技术等
