The Design And Implementation Of Web Framework Based On Ajax

With development of the Web technology and people have become increasingly demanding , users find the use of traditional methods of interaction allowsz is difficult to use and experience a bad sense on the one hand, on the other hand it is not conducive to developers to develop and maintain on the use of traditional methods of interaction. So when Web2.0 concepts have been proposed, it immediately received widespread attention and response. Compared with traditional Web 1.0 model, the core concepts of application architecture with Web2.0 model have two aspects: First is a service-oriented direction and the second is the platform-oriented direction. Web2.0 applications designed to meet the online users interact with the Web site needs to achieve the client page refresh rate closer to the native desktop application at the same time to achieve diversification of Web applications, instant and interactive user experience together. The core of the Web2.0 technology is the Ajax. Ajax technology to solve the traditional Web presentation layer lack the flexibility and interactivity of the defects be achieved through an asynchronous client and server interact and greatly enhanced the efficiency and performance of the Internet. Ajax technology is still in the developmental stage, it strengthened the ability of Web applications but there are some problems limited its application. At present, people generally integrate the various Web technologies to combine a new framework to use. Framework built-in a variety of features that can help people to develop, deploy and maintain, so Ajax has become a mainstream development approach.The Web platform in this paper to introduct the Spring framework from the open source community to use its two core mechanisms IOC, AOP and MVC framework. As the Spring itself "non-invasive" characteristics, it can be easily integrated with Hibernate. Therefore, if the Ajax technology can be a perfect combination with the J2EE platform together, then the Web-presentation layer and business logic can be separated from the better, making the presentation layer, logic layer and data layer easier maintenance and expansion in the new structure .It can be Achieve the concept of Web2.0 interactivity and platform of unity turely. In this paper, we use Ajax (YUI) technology, combined with the J2EE open-source framework to make Ajax framework and J2EE platform to reach a perfect integration and seamless connectivity programs. And use research results to develop an application to show the performance of these three great advantages and a broad space for development.
