Online Transaction System Design And Development Based On J2EE

In recent years, the development of electronic business has become a great challenge to the traditional web technologies, and Internet-based e-commerce platform has been the urgent requirement for enterprises to develop e-commerce, the traditional web technologies hasn't satisfied with the demand of the e-commerce system. With the development of software technology and Internet, J2EE technology system which representatives distributed object technology provides technical support for enterprise structure of the new Internet-based electronic business system. The J2EE platform specification defines a component-based module that simplifies enterprise development and deployment. It provides a multilayer application module of the distribute type and a series of technical standards for structures with scalability, flexibility, ease of maintenance of the e-commerce system provides a good mechanism, develop technique.The research for the development of building small and medium-sized e-commerce online system with J2EE technology is made:At first, introduced the feature of the system development the architecture and the core technology of J2EE platform are simply introduced. J2EE platform for the development and deployment of e-business application framework provides complete application architecture. Based on the J2EE platform the MVC (Module/View/Controller) design pattern and the Struts application framework are used in the design and implementation of the system.Secondly, analyzed the core function of the system in detail, the presentation layer, business layer and lasting layer are discussed. The design ideas and the application guidelines of the system are expounded in the paper. At the same time the lasting layer and the general technical means to achieve the lasting layer are researched. The architecture of the system is designed according to the MVC design pattern.Finally, the function module of the system is designed and divided according to the demand analysis of the system. The function procedure and the operation procedure are designed in the paper. Based on the above work the database design, presentation layer, business and lasting layer are designed in detail and implemented.Based on this design a multilayer, expansive and maintainability system can be got which increase the implement efficiency of the system and the reusability of the practical system. The design and implement of the system has obvious practical significance and the application value for the enterprises to develop the e-commerce system.
