【摘要】： 随着网络技术和Internet的快速发展,以B/S结构为基础的Web系统开发在信息化建设中得到了广泛的应用。构建在J2EE平台基础上的各种成熟的框架和技术促进了Web应用开发的进一步发展,很大程度上简化了Web应用系统的开发过程。但是,在越来越复杂的企业级Web应用开发领域,业务需求的不断变化以及对新技术的快速适应能力,成为Web应用开发面临的一个巨大的挑战。模型驱动架构(MDA)为上述问题提供了一种新的解决方法。它是一种新的以业务模型为中心的开发模式。它以建立和维护平台无关模型(PIM)为主要开发过程,然后根据选择的平台特性,把平台无关模型(PIM)转换为平台相关模型(PSM),并由平台相关模型(PSM)直接生成代码,完成应用系统的开发。这种开发模式能够很好地适应平台技术的变化,提高开发的效率。同时由于代码可由模型自动生成,开发人员只需维护系统的模型,所以能够更好地解决由需求变化引起的各种问题。虽然MDA具有很多优点,但是目前MDA正处在发展阶段,而Web应用开发已经有很多成熟的架构和技术,是MDA应用的一个较好的方向,如何结合这些架构和技术,应用MDA开发模式来快速开发Web应用程序,已成为软件开发人员的一个难题。本文针对这个问题,首先对传统的开发模式与MDA开发模式进行了比较,介绍了MDA开发的相关原理和技术标准,对MDA的核心技术和开发模型做了深入分析,并且介绍主流的Java Web开发模式和框架技术。然后本文提出了基于MDA来开发Java Web应用软件。结合MDA的开发原理,现有的MDA开发工具以及主流的Java Web框架技术,探讨了平台无关模型(PIM)转换为Java Web应用系统相关模型(PSM)的实现方式,并给出了这种软件开发模式的具体步骤与过程。本文将所设计基于MDA的方案应用在电信铃音广告系统实例开发中,详细介绍了需求分析、总体设计、模型建立以及模型转换、代码生成等开发过程。最后在转换生成的代码框架的基础上进行补充和部署,实现了该系统。开发结果表明,基于MDA方法来开发Web应用是可行的,能较大提高开发的效率,增强系统的可维护性,提高系统对新技术和需求变更的适应能力。
[Abstract]:With the rapid development of network technology and Internet, The development of Web system based on B / S structure has been widely used in the information construction. Various mature frameworks and technologies based on J2EE platform have promoted the further development of Web application development. However, in the increasingly complex field of enterprise Web application development, business requirements are constantly changing and the ability to adapt to new technologies rapidly. Model-driven architecture provides a new solution to the above problems. It is a new business model-centric development model. It builds and maintains leveling. Taiwan independent model (PIM) is the main development process. Then, according to the selected platform characteristics, the platform-independent model (PIM) is transformed into the platform-dependent model (PSMN), and the code is generated directly by the platform-dependent model (PSM) to complete the development of the application system. Improve the efficiency of development. And because the code can be generated automatically by the model, developers only need to maintain the model of the system, so they can better solve the problems caused by the change of requirements. Although MDA has many advantages, But at present, MDA is in the development stage, and Web application development has many mature architecture and technology, which is a good direction for MDA application. How to combine these architecture and technology, how to develop Web application program quickly by applying MDA development mode, Has become a problem for software developers. In order to solve this problem, this paper first compares the traditional development mode with the MDA development mode, introduces the related principles and technical standards of MDA development, and makes a deep analysis of the core technology and development model of MDA. It also introduces the mainstream Java Web development mode and framework technology. Then, this paper presents the development of Java Web application software based on MDA. Combined with the development principle of MDA, the existing MDA development tools and the mainstream Java Web framework technology, This paper discusses the implementation of the platform independent model (Pimm) to the Java Web application system model, and gives the concrete steps and process of this software development model. In this paper, the scheme based on MDA is applied to the development of telecom ring tone advertising system. The requirements analysis, overall design, model establishment and model transformation are introduced in detail. Finally, the system is implemented on the basis of transforming generated code framework. The development results show that it is feasible to develop Web application based on MDA method and can greatly improve the efficiency of development. Enhance the maintainability of the system and improve the adaptability of the system to new technologies and requirements changes.
