Research And Application Of Web Framework Based On EDSH

Abstract:With the rapid development of Web Technology, Web application has become more and more popular. How to quickly and easily develop applications with beautiful interface and powerful functions, with strong scalability, reusability and low couple is a key consideration of issues for developers. In this case, Web framework came into being, framework has made a significant contribution for software reuse, besides, it’s also an important guarantee to improve the efficiency of software development. Currently, popular Web framework can’t meet the needs of each Web application development, so look for a new framework for developing Web applications has become a priority for developers.The first, this paper introduces the research background and meaning of the topic and domestic and overseas research status of Web application framework and RIA technology; the second, this paper analyzes the application system model, the RIA technology, JSON technology as well as the principle and advantage of Ext JS framework, DWR framework, Spring framework, Hibernate framework; the third this paper analyzes the problem of current used frequently Web application framework-SSH, and then this project aiming at the problem of current Web application framework, starting from the presentation layer of Web application, integrate a new Web framework-EDSH framework. This framework using the current relatively popular in the Ext JS and DWR framework to replace the Struts framework of SSH, has reduced the coupling between the level, improved the scalability and maintainability of the system; then the EDSH security problems of the development of web application framework are studied, according to the main safety problems put forward the concrete solution, the use of the development of Web application framework provides the reliable security.Finally, by using EDSH framework in the fixed assets investment plan system, has proved modular degree of new framework is high, besides, it’s easy to develop and maintain. Compared with the SSH framework, the new framework not only improves the aesthetics of the interface, shortens response time, reduces the developers’work, improves the efficiency of application development, and make the system more reliable security performance.
