一、項目簡述

功能：一個基于JavaWeb的網上書店的設計與實現，歸納 出了幾個模塊，首先是登錄注冊模塊，圖書查找模塊，購 物車模塊，訂單模塊，個人中心模塊，用戶管理模塊，圖 書管理模塊等。 該項目是javaJeb技術的實戰操作，采用了MVC設計模 式，包括基本的entity, jscript, servlet,以及ajax異步請 求，查詢分頁，持久化層方法的封裝等等，對javaweb技 術的鞏固很有幫助，為J2EE的學習打下基礎，適用于課程 設計，畢業設計。

二、項目運行

環境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持)。

項目技術： JSP + Entity+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload 等等。
