基于Ajax技术及J2EE架构的RIA集成框架的研究与实现
|
摘要
随着Web2.0的兴起,如何提高用户交互体验成为广大开发设计人员讨论的热点,作为Web2.0核心技术的Ajax也逐渐得到广泛的关注、研究和应用。Ajax最大的优势之一是能够提供浏览器端和服务器端异步交互的功能,这种交互方式有效地降低了服务器的负担。本文通过深入研究Ajax技术及其框架和J2EE体系结构下最流行的开源框架之一WSH (WebWork+Spring+Hibernate),结合目前比较成熟的MVC模式,根据各自的特点,提出了基于Ajax技术及J2EE架构的RIA集成框架,从而提高程序的可重用性和易扩展性,并降低后期维护的复杂度。
在本文提出的基于Ajax技术及J2EE架构的RIA集成框架的基础上,实现了横向审批管理系统的具体设计和开发,进一步论证了将Ajax框架融入到J2EE框架中的可行性和可操作性。在具体的应用开发中,实现了主动刷新请求、被动定时局部刷新,并利用Ajax中DWR框架的反推机制,实现了服务器端推送功能。最后经过总结得出结论,该集成框架能够降低表现层、业务逻辑层和数据持久层之间的耦合度,使得Web应用层次分明,可重用性强,而且通过Ajax技术及其框架的使用,解决了很多传统Web应用中普遍存在的问题,在很大程度上改善了浏览体验。
在具体的设计实现上,本文提出了将DWR框架和WSH框架完美整合无缝连接的开发模式,并将该开发模式应用到横向审批管理系统的实际开发中,以实际应用展示了这种整合所带来的巨大优势。
With the rise of Web2.0, the improvement of user interaction experience becomes a hot topic among the majority of developers and designers. Ajax, as the core technology of Web2.0, has been gradually widespread concern, research and application. One of the biggest advantages of Ajax is the ability to offer asynchronous interaction between browser-side and server-side. This approach of interaction can effectively reduce the burden on the server. Through in-depth study on Ajax technology and WSH which is one of the most popular open source framework under the J2EE architecture, combining the MVC pattern which is relatively mature nowadays, according to the characteristics of them, the article proposed a RIA framework which is based on Ajax technology and J2EE architecture, it can not only improve the reusability and program scalability, but also reduce the complexity of post-maintenance.
Based on the integrated framework, this article has been achieved the specific design and development of horizontal approval management system, further demonstrating the feasibility and operability of this framework. The article realized active and inactive refresh, also achieve the server-side push by using the DWR inverse mechanism in Ajax. Finally comes the conclusion that the integrated framework can reduce the coupling among the presentation layer, business logic and data persistence layer, in the same time, it makes the layers clear in Web applications with highly reusable. By using Ajax and its framework, this article has been solved many problems in traditional Web applications and greatly improved the interaction experience.
This article proposed a development model with seamless integration between DWR and WSH framework in specific designing and implementation. With the using of this development model, the article achieved horizontal approval management system which demonstrates the enormous advantages of this integration.
