Research And Implementation Of J2EE WEB Application Base On Struts Framework

With the rapid development of network technology and the wide use of J2EE platform, the multi-layer web structure base on B/S has developed gradually, and become the mainstream of the web application development. But low maintainability and reusability, and inflexibility are very common phenomena in Web applications. Consequently, hierarchical designing, the framework of each sub-tier, and selection of development technology become more and more important with complexity of requirement analysis, constraints of R&D time cycle, and requirements of system stability, extensibility and maintainability.This thesis is just base on these questions, through analyzing of J2EE platform technology, the deep study and research of the MVC pattern and struts framework, and combining with the author's practical experiences, expatiate how to use struts framework to make Web system framework hierarchy clear, improve system expansibility and maintainability, by optimizing the Web development framework and using design pattern.In order to achieve the research purpose, the main work of thisthesis is following: research the thought of the MVC design pattern deeply and analyze the segment and develop process of struts framework. According to specialty of J2EE Web application, design the thought of developing by layers using on struts framework. Finally, combining with the author's practical experiences, implement scheme of the five layers B/S framework base on struts framework with that thought. And then makes a discussion about each tiers of website. In order to improve efficiency and validity of programming, the thesis also makes a discussion of some design pattern on J2EE.
