1、项目介绍及开发技术
1.1 项目介绍
传统办法管理信息首先需要花费的时间比较多，其次数据出错率比较高，而且对错误的数据进行更改也比较困难，最后，检索数据费事费力。因此，在计算机上安装民宿租赁系统软件来发挥其高效地信息处理的作用，可以规范信息管理流程，让管理工作可以系统化和程序化，同时，民宿租赁系统的有效运用可以帮助管理人员准确快速地处理信息。
民宿租赁系统在对开发工具的选择上也很慎重，为了便于开发实现，选择的开发工具为IDEA，选择的数据库工具为Mysql。以此搭建开发环境实现民宿租赁系统的功能。其中管理员管理用户，新闻公告。
民宿租赁系统是一款运用软件开发技术设计实现的应用系统，在信息处理上可以达到快速的目的，不管是针对数据添加，数据维护和统计，以及数据查询等处理要求，民宿租赁系统都可以轻松应对。
1.2 开发技术
Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

3、功能截图
用户信息管理：用户信息的查询管理，可以删除用户信息、修改用户信息、新增用户信息，还进行了对用户名称的模糊查询的条件。
民宿收藏管理：根据民宿收藏进行条件查询，还可以对民宿收藏进行新增、修改、查询操作等等。
公告信息管理： 根据公告信息进行新增、修改、查询操作等等。
4、数据库表结构设计
