Design And Implementation Of Web Framework Based On J2EE

Today,the science and technology change rapidly, computer science plays an important role in the study of all fields, with the development of computer and network technology, enterprise application has started to use the Internet as the platform. Web technology based on B/S (Browser/Server) structure is adopted in the management information system more and more. Design and development of application framework can effectively regulate the system structure; improve the reusability of the code. There are many open source framework, but still can not meet the enterprise specific business operation, stability, high efficiency and scalability aspects of demand.Based on a web application framework co-designed by the author which has been successfully applied in a Management Information System project, this thesis discusses the design and implementation of the web application framework (B/C Clients Framework, BCF) which can adapt to multi-kinds of clients.While been designed independently, the BCF framework makes use of many advantages of prevailing open source frameworks. It has the features of maneuverability, high performance, stability, extendibility, etc. BCF improves on the MVC design pattern, and the wholly separation of business logic and presentation logic makes it possible to set the same business logic for different kinds of clients. BCF handles database transactions and resource management uniformly; it adopts a concise and effective objects-DBMS mapping mechanism. BCF also supports unit test, business use case test and local debugging of business logics. The framework is reusable, both codes and design can be reused to some extent later on.As the core of the project, BCF has been used in the company and has got a good result.
