摘要

在网络高速发展的时代，众多的软件被开发出来，给用户带来了很大的选择余地，而且人们越来越追求更个性的需求。在这种时代背景下，房东只能以用户为导向，所以开发租房网站是必须的。
系统采用了Java技术，将所有业务模块采用以浏览器交互的模式，选择MySQL作为系统的数据库，开发工具选择 eclipse来进行系统的设计。基本实现了租房网站应有的主要功能模块，本系统有管理员；首页、个人中心、用户管理、房屋类型管理、房屋信息管理、预约看房管理、在线签约管理、租赁评价管理、交流论坛、系统管理，用户；首页、个人中心、预约看房管理、在线签约管理、租赁评价管理、我的收藏管理，前台首页；首页、房屋信息、交流论坛、房屋资讯、个人中心、后台管理、在线客服等功能。
对系统进行测试后，改善了程序逻辑和代码。同时确保系统中所有的程序都能正常运行，所有的功能都能操作，并且该系统有很好的操作体验，实现了租房网站。
