The Research And Application Of MVC Design Pattern And Struts Framework

With the rapid development of network technology and the wide use of J2EE platform, the multilayer web structure base on B/S has developed gradually, and become the mainstream of the web application development. But even using the most advanced software platform J2EE, it also has difficult to implement the application. In the design of multilayer web structure, it has ubiquitous defects that reusable of application is low, the maintenance work is heavy and the adaptability of software is weak. So how to organize program to achieve write, upgrade, maintenance and extend easily and effectively, is one of the focuses of present Internet technical development.This thesis is just base on these questions, through 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 resolve the questions by optimizing the Web development framework and compiling code builder.In order to achieve the research purpose, the main work of this thesis is following: research the thought of the MVC design pattern deeply and analyze the advantages and shortcomings of this pattern and its applicability scope. Analyze the structure of struts framework in detail that implemented the MVC design pattern. Based on the struts framework, through the analysis and contrast of the implement of the multilayer web structure, finally summarize the technical implement scheme of the five layers B/S framework, and then design a reasonable web development framework base on struts. To improve efficiency and validity of programming, the thesis also makes a discussion of the code builder. At the end of the thesis, illustrate the way of realizing the system by an instance, and validate its feasibility.
