這篇文章主要為大家展示了“Java如何實現在線購書商城系統”,內容簡而易懂,條理清晰,希望能夠幫助大家解決疑惑,下面讓小編帶領大家一起研究并學習一下“Java如何實現在線購書商城系統”這篇文章吧。
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。
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。
