Web Research And Application Based On The J2EE Platform And MVC Model

With the rapid development of network technology,on a global scale the Internet has become an necessary tools for information exchange,technical cooperation and commercial activities.Web as the most widely used worldwide and the most effective accessing and publishing information of the media,today enterprises more and more depend on a variety of Web applications to enhance the operation and management effectiveness.In this situation,application and development based on the web become hot spots of computer research.Enterprise Edition(J2EE)is a standard development platform in enterprise application by sun company.It is for us to develop enterprise web application with abubdant technological choices.However,a high quality system depends on the support of a well-designed structure.How to correctly use core J2EE technologies to design and build a strong,flexible,and reusable web Framework is the challenge we have to face.MVC design pattern which is based on J2EE Web application development software design model of choice,has great advantages in the development of multi-tier web applications by separating the data and its view.Based on J2EE platform,Struts is a framework implemented with MVC design pattern.Struts can reduce the burden of constructing the multi-tier web applications by providing a reusable software architecture.But when developing J2EE projects using the standard Struts framework,it demonstrates some shortcomings,such as the low ratio of the reuse of the internal modules,some components' not meeting the actual requirements, the lack of the components aiming to develop the normalized model layer,the complexity when extending the verification framework.Under the analysis of J2EE framework and MVC model's basis theory,the paper researches the Struts framework's the realization of principles and characteristics,and analyzes the shortcomings of constructing the view part of the Struts framework by using JSP and Taglib.By using the advantages of XML technology and overcoming the Struts framework's some shortcomings,the paper effectively explores and researches the key technologies and the application of the StrutsCX model.Against the view part of Struts framework of MVC design pattern, the StrutsCX model proposes the solution that the view part uses XML / XSLT replacing JSP,the solution will separate content and the displaying content to avoid developing systems slowly and maintain difficultly.At the same time,the output XML documentation of the system which can be converted into a variety of document file format by XSTL style sheet meets a variety of client requirements too.
