Research And Application In E-Government System Model Based On Web Framework Of J2EE

In recent years,with the rapid popularization of Internet,information technology has got a great development,and has an effect on people's life.In this situation,the information-based construction of government and enterprises have stepped up.The application of E-government and E-business has become more and more broad.Because of the changes in the function of government,the old E-government system can't satisfy the demand of government for their unreasonable structure,little expansibility,difficulties in maintenance,being hard to share resource.It is a trend to transform the information communication way of government department and promote their efficiency through exploring the enterprise application of Web.J2EE has concentrated on the enterprise application since it exists,which achieves a great success.However,for most of small and media enterprises,because of the existence of EJB,the traditional scheme of J2EE is too complex,which brings difficulties to the development of projects.Therefore,it is necessary to construct a lightweight Web framework that is equipped with low intrusiveness and able to make the J2EE platform technology in a coupling state.This article research on the J2EE system structure,analyzes the classic J2EE structure and the J2EE architecture development phase.Based on the Web architecture system,this article makes a discussion from performance tier,domain tier and datasource tier.Meanwhile,the article inducts there kinds of Web application frameworks:Struts,Spring and Hibernate,research on the three kinds of frameworks' principles and the characteristic separately.It puts forward one kind of new framework,which integrate Struts,Spring and Hibernate framework.Finally,this article takes a project,"Technological Project Declaring and Approving Management System",as background,researching the application of the lightweight architecture in enterprise information systems.The architecture of this system is based upon the lightweight J2EE architecture and is designed using a layered architecture.This article provides the concrete develop process of declaring information management module.
