The Research And Implementation Of Web Application Based On Ajax And J2EE Framework

At present, development of enterprise-class Web application in J2EE platform have been gradually the fundamental mode of enterprise MIS. The use of framework can simplify developing process and shorten developing time. Because the complicated configuration and deployment, the EJB model of the J2EE hasn't been extensively applied. The development of open-source framework provides the design of Web application with a new choice. But the amount of open-source framework is numerous, and each framework has respective strengths and weaknesses, apply to different situations. So how to choose appropriate frameworks to set up enterprise-class Web application system is a problem which needs to be resolve. In addition, the interaction and interface of traditional Web application is poor, so this question limited the development of Web application.This paper aims at the problems in the design process of Web application and presents a kind of solution of problems--the framework named SSH(Struts+ Spring+Hibernate)+ Ajax. By the Integration of three kinds of framework and Ajax, this framework has advantages of each type of framework and Ajax. Such as, this integrated framework have the clear control structure like Struts, and the convenience of operating database by using Hibernate, and loosely coupling functional module by using Spring's IoC container, and the flexible configuration and easily transplant. Through the use of Ajax, Browser can asynchronous communicate with Server. Moreover, the interaction and interface of Web application has been enhanced and the user experience has been improved. The Web application with friendly interface and convenient operation and good scalability and reliability can be developed by using the SSH+Ajax framework.According to the J2EE development technology, this paper details the research and implementation of SSH+Ajax framework and the point is the method of integrating the Ajax technique and the traditional Web framework. At last, using the SSH+Ajax framework, design and realize the"Comprehensive Administration Management System"of Beijing entry-exit inspection and quarantine bureau.
