【摘要】 软件框架技术是当今B／S系统开发的重要技术。本文对J2EE架构的框架技术作了较为深入的分析和研究，阐述了J2EE企业级软件开发架构、设计模式、软件框架及组件技术等相关技术；并且针对当前在B／S架构设计中普遍存在的页面和代码不能合理分离、开发队伍不能很好协作、系统的扩展性差、维护成本高等问题，针对性地引入了当前最为流行的基于MVC设计模式的Struts框架技术，重点研究了其在企业级J2EE系统应用中的关键技术。论文在需求分析及系统设计基础上，详细论述了应用Struts框架进行民航地面运行监控系统开发的关键技术问题，包括：视图组件功能加强、控制器组件成组业务处理及防表单重复提交机制、模型组件的ORM映射机制、数据持久化操作、EJB组件开发等；此外，在充分实践的基础上，针对Struts框架问题中最重要的模型组件问题和数据持久化问题做进一步的分析和论述，明确指出其中的主要缺点与不足，并针对性地引入轻量级模型组件技术及数据持久化框架技术，丰富发展了Struts框架并成功应用到系统开发中，很好地兼顾了系统稳定性、可扩展性和可维护性的要求，取得了良好的效果。更多还原

【Abstract】 So as B/S for the distribution software system of representative, development has become a kind of general technical configuration in the present enterprise level development of application software. But develop this kind of system, its scale and complexity will far surpass a lot of traditional softwares, these must be for traditional development method put forward with means to challenge sternly. Therefore among software structural design, will make the process of developing of software more efficient, guarantee that the software defect developed is more few, and still make software meet the demand that user expands constantly.It is come to that software frame technology is that software project develops in practice, a general method of solving this kind of problem, this paper based on Struts frame technology of configuration does analyse and study relatively further, have elaborated J2EE software related technology of developing configuration and developing pattern, software frame and assembly technology, and aim at at present B/S and the page surface in configuration design can not separate and develop troops reasonably can not cooperate very well , in article, have studied mainly that software frame technology is being developed J2EE application in distribution type system. It is relatively extensive to have adopted present application Struts frame work, have analysed Struts Advantage and the characteristic of frame, aim on the foundation of ample practice Struts assembly management in frame is simple, database visit assembly can not solve different type Database such as the compatible problem of data and is below have put forward improvement, it is rich and has developed this frame.更多还原
