Design And Implementation Of J2EE-based Online Shopping Mall

With the rapid development of the Internet, online shopping has become an indispensable part of people’s lives. Especially in recent years, with the rise of Tmall, Jingdong Mall and so on, more and more people have joined the ranks of online shopping, such as Tmall in "11.11", just that generates hundreds of millions of transactions a day there, which is enough description of how popular online shopping. As to the status of today’s network financial mall, it is very necessary to learn how to develop a standout network financial mall in a number of online shopping system which is used to achieve J2EE-based network financial mall needs.Compared to the traditional financial products sales, online shopping has many advantages. For sellers, they may save the cost of business. Ministry of construction of the traditional centralized services,even also the customer to select lightbusiness department of the way, do not need such as the traditional counter service, in addition,most financial products is paid more attention to shopping online channels.This paper first researches the shopping process of network financial mall to understand the business needs of network financial mall. And on the basis, we conducted a needs analysis and a data modeling, design the overall architecture and database system in detail. And According to the features of network financial mall, the system is divided into six functional requirement modules that include commodity management, shopping cart management, order management, payment, user management and system security. Then according to the different roles played in the system, the system is divided into ordinary members, registered shop system members and administrators composed of three characters. And by some key technologies based on J2 EE, detailed design and implementation of them are carried out.1. First,the paper analysis the online mall system based on J2 EE,and with the demand modeling,system modeling,the paper gives the preliminary outline of the outline of the whole system2. Second,the paper design the online store based on J2 EE. On the basis of demandanalysis,and the design of the overall structure of the system and the framework of the module separation,the paper introduces the main design of the system.3. At last,the paper mainly realize function module of online shopping mall based on J2 EE,and then,the paper shows the process of test in the end.Finally, the system is deployed on the server Tomcat, the use cases and test process are implemented. Through the analysis of test results, the feasibility and effectiveness of the online shopping mall system meet the design requirements, and each features have been correct implementation and the system satisfies the needs of users.
