Research And Implementation Of WEB Framework Based On J2EE

Along with the economical globalization development, the market competition becomes more and more intense. The enterprise in order to improve the capacity of response to the market needs to strengthen unceasingly its own resources control, and needs practically to strengthen relation with the industrial chain upstream and downstreams enterprise. Enterprise's service and the optimization need formidable application system such as ERP, SCM, CRM, PLM and so.on. In recent years, computer technology developed more rapidly, the Internet obtained the rapid popularization, the network coverage and the band width had a big promotion. These essential factors promoted the WEB application system rapid development together.In application system development based on the WEB, J2EE holds an extremely remarkable status. From first the classical long-distance EJB framework, to the local EJB framework, continuously to recently the popular lightweight container framework, the multitudinous enterprise and the development facility makes a lot of research in it, develop many excellent Web frame based on J2EE, for instance Struts framework, Spring framework and Hibernate framework and so on.This article researches on the J2EE system structure, analyzes the classic J2EE structure and the J2EE architecture development phase. This article has conducted the detailed research in the new development of J2EE technology named the lightweight container and its realization. Revolved the Web architecture system, this article makes a discussion from performance tier, domain tier and datasource tier, and researches on their architecture patterns. In the performance tier, the article selects the Struts framework.In the domain tier, the article selects the Spring framework.In the datasource tier, the article selects the Hibernate framework. The article researches on the three kinds of frameworks' principles and the characteristic separately.Based on the above research, the article proposes one kind of new framework, and integrates Struts, Spring and the Hibernate framework in it. The integratedframework is clear, at the same time has contained Struts, Spring and the Hibernate frameworks' outstanding characteristic. It has used oriented interface principle of design.All that effectively enhances the development efficiency, and increases the software's capacity of the extension-and the maintainability. This article designs and realizes a buy-sell-save application system based on the integrated framework finally.
