An Ajax / Aop, Web Frameworks And Achieve

As the Internet has become more mature, WEB applications featuring responsive user interfaces and maintainability capabilities have become increasingly popular. However, classic WEB applications have generally exhibited problems such as slow performance and heavy network traffic. So, a new design for the web -- Ajax appeared recently. Because Ajax minimizes traffic to the server by sending and requesting just the minimum amount of data needed, it can make Web-based applications more responsive, interactive, and customizable. In short, Ajax recreate the seamless user experience of most other desktop applications.Now how to integrate Ajax technique into MVC design pattern and J2EE container (Such as Spring), especially realize the combination of loose coupling, have not a good solution. If adopt traditional Object Oriented Programming, we should face the problem of code tangling and scattering. So in this paper, proposed to resolve the problem by AOP(Aspect Oriented Programming) to change original J2EE framework behavior. AOP allows the separation of crosscutting concern into single units called aspects, which are modular units of crosscutting implementation. So we can integrate Ajax into J2EE development framework by AOP.In this paper, firstly the principle of Ajax's implement and it's component technologies will be researched. Secondly the limitation of Object Oriented Programming will be researched, AOP how to resolve this problem and the implementation of AOP language. As the result of these research, a Ajax framework model - Ajax/AOP WEB framework - based on the AOP will be gived. Then the implementation of this framework and the benefit it haved compare with the classic solution will be discussed. In the end, the application of this framework in project will be introduced. The testing illustrates this framework can resolve the limitation of classic WEB application and Object Oriented Programming, and it have good performance.
