Design And Implementation Of The Chinaunicon Mobile Payment System Based On J2EE Structure

Chinaunicom mobile payment is a service that the users can realize individual payment with the support of bank cards. The maximal advantage of the payment lies in effective integrating the banks, merchants and consumers.The payment platform that Chinaunicom Company and Chinaunionpay Company join developed provides pay service for the Chinaunicom CDMA mobile consumers , including services such as bank card balance inquiry,paying,consuming and so on.We have designed Chinaunicom payment system according to demanding analysis, It includes system design principle,system main frame,software structure. Finally, detailedly analyses and designs the safe transction of the payment system.Having designed entire system frame, the main body of this thesis having studied the realization of the payment system .we adopt J2EE system structure in the process of realization. Respectively detailed design to Web tier, business logic tier, data persistence tier, and database tier. It focuses on improving the resue, maintainence and extention of the enterprise application by use of framework and EJB design patterns. Thus the paper not only has theory base but also has successful practical significance.The main part works in system develop:1): Various design patterns of EJB have been used to realized the business tierBusiness tier has Packaged business logic of the system and the core data , It's the core of the entire system , web tier only carry out interactive with the back-end database by the help of business tier. The EJB modules of the business tier being divided to two parts by analying basis of function module, being to be independent in system: Business logic module and data persistence module, adopt SessionBean and EntityBean respectively to realize, have used various EJB design patterns, feasible business tier be easy to stretch out and draw back, and be able to effective make use of the network resource.2) Realize the modules of WEB tier based on the Struts frameThe web tier modules mainly accomplish the expression and processs controlled of system. The system web tier is developed based on Struts. Its flow control,the processing of user request and consumer's expression is stricty separated .It feasibles WEB tier has fine readability and upkeep.In the process of entire systematic design and realization, author's main part works having been used for the earlier need analysis, systematic design , the design of systematic software frame and the realization of some function modules.
