This article is focused on the analysis of the applied environment of electronic mall and the main achievement function, for the purpose of describing the design and implement process of system is based on the web application developed with multistandard enterprise application standard JAVA EE,framed with classical MVC model architecture,and realized through the bination of lightweight framework SSH and front desk Ajax technology. In the design process a full range of application development software engineering development ideas was used in theUML modeling of the project,which included class diagrams, sequence diagrams. The system is based on B / S distributed architecture to meet a broad range of requirements.Key words: Electronic Mall, SSH, Ajax, Framework 3 1. 引 言隨著網(wǎng)上購物的迅猛發(fā)展，電子商城大量涌現(xiàn)，而電子商城的出現(xiàn)不僅改變了人們傳統(tǒng)的購物方式，也逐漸的影響著人們的消費(fèi)觀，一個好的電子商城不僅能給客戶帶來方便，更能給企業(yè)帶來巨大的財富。本商城主要利用JavaEE 與 Ajax 技術(shù)進(jìn)行開發(fā)，具有很強(qiáng)的安全性、可靠性和可擴(kuò)展性。其前臺實(shí)現(xiàn)了從商品選購到訂單提交整個業(yè)務(wù)流程，后臺實(shí)現(xiàn)了對整個系統(tǒng)的管理，就整體功能而言，能滿足基本的網(wǎng)上購物需求，能讓用戶感到便捷、快速，讓企業(yè)管理、維護(hù)更簡單。 4 2. 設(shè)計目的與任務(wù)隨著信息化技術(shù)在生活中的應(yīng)用越來越廣泛，網(wǎng)上購物也逐漸成為人們的一種生活方式。本系統(tǒng)正是基于這樣一種環(huán)境下應(yīng)運(yùn)而生。本電子商城分為前、后臺兩部分，前臺主要實(shí)現(xiàn)會員的網(wǎng)上購物業(yè)務(wù)流程，后臺則由各種管理員對商城會員、商品、定單等內(nèi)容進(jìn)行管理。3. 需求分析本電子商城分為前后臺兩部分，前臺主要包括非會員和會員用戶，后臺分為商品管理員、訂單管理員、會員管理員和系統(tǒng)管理員。在系統(tǒng)中依據(jù)用戶的權(quán)限執(zhí)行相應(yīng)的功能。系統(tǒng)用例圖如下所示：業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè) 業(yè)業(yè)業(yè)業(yè)業(yè)use業(yè)業(yè) 業(yè)業(yè) 業(yè)業(yè)業(yè)業(yè)業(yè)use業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)useuseuseuse 業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)業(yè)圖 31 系統(tǒng)用例圖 5 4. 系統(tǒng)設(shè)計 分層模式本系統(tǒng)是基于 B/S 模式開發(fā)的 JAVA EE 多層體系結(jié)構(gòu) WEB 應(yīng)用。系統(tǒng)開發(fā)主要分為以下幾層：表示層、業(yè)務(wù)層、DAO 層、持久層。業(yè)務(wù)層和 DAO層都通過接口與其它層進(jìn)行連接從而減小了各層之間的耦合度，實(shí)現(xiàn)高內(nèi)聚、低耦的思
