Research And Application Based On MVC Design Patten On Web Application Framework

With the development and the popularization of Internet at very fast speed, web application presents the multi-purpose tendency, and that puts forward the more and more high demand to the support of multi-view user interface, the expandability and easy maintenance of web application framework. However at present the procedure-oriented programming of web application techniques are hard to adapt to the new changes. Aiming at the problem of web's application framework presently, this thesis proposed the improving solutions based on Struts framework and a ,convenient configuration file's manager of web application framework.The main work of this thesis as follows:(l)In view of Struts framework's deficiency, applying the Object Oriented programming technique and MVC design pattern, analyzing detailcdly the every tiers' key realization technique of framework.(2)Analysing the merit and deficiency of Struts frame and support mechanism of multi-view user interface, adopting XML and XSL techniques, improving on the view part of Struts controller, realizing support of multi-view user interface in the controller.(3)Aiming at the hard configured deficiency of Struts' configuration file, designing and realizing a configuration file's manager based on JMX technique, it has characteristic of dynamic remove and installation and convenient flexible management , which convert the complicated modification to the configuration file into the simpleness.(4)Designing a system of digital photocopy in the internet and verifying the research conclusion of this thesis.
