摘要

在網絡高速發展的時代，眾多的軟件被開發出來，給用戶帶來了很大的選擇余地，而且人們越來越追求更個性的需求。在這種時代背景下，房東只能以用戶為導向，所以開發租房網站是必須的。
系統采用了Java技術，將所有業務模塊采用以瀏覽器交互的模式，選擇MySQL作為系統的數據庫，開發工具選擇 eclipse來進行系統的設計。基本實現了租房網站應有的主要功能模塊，本系統有管理員；首頁、個人中心、用戶管理、房屋類型管理、房屋信息管理、預約看房管理、在線簽約管理、租賃評價管理、交流論壇、系統管理，用戶；首頁、個人中心、預約看房管理、在線簽約管理、租賃評價管理、我的收藏管理，前臺首頁；首頁、房屋信息、交流論壇、房屋資訊、個人中心、后臺管理、在線客服等功能。
對系統進行測試后，改善了程序邏輯和代碼。同時確保系統中所有的程序都能正常運行，所有的功能都能操作，并且該系統有很好的操作體驗，實現了租房網站。
