Ajax Framework And JSON Technology Research And Application In J2EE Architecture

With the advent of the Web 2.0 era, users have a new understanding about the user interface design and interaction design of internet products. The interaction design has gradually become an important criterion for evaluating the merits of Internet products. In order to meet user’s growing demand of system experience, to change the traditional access mode (request-response) of B/S system and import Ajax technology into modern MIS have become an irreversible trend. The asynchronous request access patterns of Ajax and their characteristics of partial refreshment can reduce the network load, share the burden on the server and avoid the emergence of blank pages in the user access, thus greatly improve the user interaction of Web MIS and give users a new experience.This subject focuses on efficient integration of Ajax technology with existing J2EE framework system. In this article, I firstly introduce the concept of Web2.0 and the current mainstream technologies of RIA, and especially focus on the in-depth understanding of Ajax’s principles and the comparison of different popular Ajax frameworks to analyze their strengths and weaknesses and select the suitable framework for the actual project. Secondly, I analyze and sum up the hidden dangers of introducing the Ajax technology into system. Finally, several solutions are given through the study of relevant knowledge.After the preparations of theoretical study, I set up a software development framework system of Dojo+Webwork+Spring+Hibernate to maintain the system low coupling and make the Ajax framework technology efficiently integrated into the system at the same time. And then select JSON which is more efficient as the data load format for Ajax applications through experiments. Last, I successfully apply the DWSH framework system to the actual project "Logistics provider management platform based on the PaaS" to provide a stable and scalable basic framework structure. The system achieved a good practical result, which proved the rationality and feasibility of the DWSH framework system’s application in the development as well as the guiding role, the practical significance and research necessity of my subject.
