Based On J2EE Structure And The MVC Pattern Research And Implementation Of Bank Sales Management System

With the rapid development of computer and network technology, more and more companies are getting out of the traditional manual management to information management. In the course of the evolution, when the structure and business process of the enterprise were changed, old systems would not meet the changes, and we have to establish a new one to adapt. So establishing an efficient and flexible process management methods and a framework that easy to maintain have been one of the developing trends of business system. J2EE with the support of workflow technology is a platform which have good security, flexibility, reusability and malniainability, so it is an ideal choice to build the new business systems.According to characteristics of existing bank credit card, this paper firstly introduces principles and characteristics of web system development in J2EE Architecture, MVC model and some developing plans following the MVC design and their characteristics, then explains the roles the Struts, Spring and Hibernate played on different tiers in their respective system. In this new architecture, Struts takes charge of the presentation tier, finishing page displays and responding user's requirements; Spring takes charge of business logic tier, completing the business logic and management of application programs; Hibernate takes charge of data persistence tier, completing data persistence on the basis of analysis on Multi-tier J2EE web systems.At the same time, it points out the advantages after the integration and analyzes characteristic of the integrated application model which introduces DWR framework of Ajax. During the period of function designing, a set of scheme is designed successfully that could accomplish authority control of the overall system and function of process management. It can also simplify the table structure of background management and increase flexibility of process configuration. In order to give full play of the integrating advantage between Struts, Spring and Hibernate and effectively reduce the dependence between the tiers. Finally, this paper constructs a stable management system which can implement the processes of applying changes of credit card limit, processing application of changing credit card limit, getting feedback of changing credit application and risk control on the foundation of Struts, Spring and Hibernate framework and Oracle database.
