该项目采用的技术实现

后台框架：Spring、SpringMVC、MyBatis

UI界面：jQuery 、JSP

数据库：MySQL

提示：以下是本篇文章正文内容，下面案例可供参考

一、系统功能

系统分为前台用户界面和后台系统管理：

1. 前台用户界面

用户注册、用户登录、用户中心、浏览房源、房源搜索

查看房源明细、发布房源、提交合同、新闻公告、留言交流

2. 后台系统管理

用户管理：用户列表、用户删除、用户查询

新闻管理：新闻列表、添加新闻、修改新闻、删除新闻、查询新闻

房屋管理：房屋列表、房屋删除、分页查看

留言管理：留言列表、留言删除、留言查询、留言回复列表、回复查询

租赁合同管理：合同列表、查看合同、删除合同

管理员管理：管理员管理、新增管理员、编辑管理员、删除管理员等

技术栈

1. 后端：Spring+SpringMVC+Mybatis\
2. 前端：JSP+CSS+JavaScript+jQuery
