【摘要】 随着计算机科学技术的发展和普及,特别是计算机在国民经济中的广泛应用,作为计算机灵魂的软件在社会生活中,尤其是在现代企业中得到广泛的应用。拥有优秀的跨平台特性的Java技术目前在企业应用中占优势,然而部署标准J2EE平台企业级应用太过于复杂且费用高,导致许多中小型企业从技术和资金方面考虑而不愿意或不能够进行这种企业级应用。开源软件是当今计算机工业界最具活力的领域,是软件行业发展的新趋势,它对尚处在童年的中国计算机工业界的意义尤其重大。文章通过研究开源技术软件,提出基于开源Struts框架和Hibernate持久性机制的轻量级J2EE框架,从而为中小企业提供了一个经济的、快速开发部署、稳定而可扩展的企业级应用解决方案。文章首先就J2EE技术和开源软件做了一个论述,根据当前开源技术的发展选择了适合企业应用的开源软件,说明了如何将这些开源软件配合使用,以进行企业级开发部署。接着对一个基于MVC模式的Struts框架和数据持久性框架Hibernate的进行研究,着重于讨论Struts是如何实现MVC模式以及Struts的各组件是如何协同工作的,研究了Java对象持久化技术原理及Hibernate的对象关系映射框架实现机制及工作原理。结合Struts和Hibernate框架,提出了一个开源的轻量级J2EE框架,并将此框架应用于重庆市巴南区卫生管理系统项目的开发。此系统已于2005年3月交付给用户使用,用户反馈良好,从而验证了应用该框架可以达到快速开发稳定可扩展的企业级应用。最后本文分析了企业使用开源技术的利益和风险,对论文所作的工作进行了总结并指出了进一步的研究工作。更多还原

【Abstract】 Along with the development and the popularization of computer science and technology, especially the widespread application of computers in the national economy, software, as computers’soul, obtains its widespread application to the social life, in the modern enterprises in particular. The java technology which has outstanding cross platform characteristics enjoys its superiority in enterprises at present; however, it is too complicated and costly to deploy enterprise level application of the standard J2EE platform. Therefore some medium and small-scale enterprises are unwilling or unable to carry out this kind of enterprise level application considering its technology and their fund. Open Source Technology is the most promising field in current computer industry domain and is a new trend for the development of software profession; what’s more, it possesses great significance in facilitating the development of chinese computer industry domain which is still in its childhood.This article proposes a lightweight J2EE framework on the basis of open source framework Struts and Hibernate of persistence mechanism, and describes how developers apply Open Source Technology so as to provide medium and small-scale enterprises an enterprise level application scheme which is economical, fast to develop and deploy as well as stable and expandable.This article firstly does a general elaboration on J2EE technology and Open Source Technology, then choose Open Source Technology which suits the enterprise application according to the development of current open source technology. It also explains how to make full use of these different kinds of Open Source Technology so as to carry out enterprise level development and deployment. Then, it explores Struts framework on the basis of MVC mode and data persistence frame Hibernate, paying more attention to discuss how Struts realizes MVC mode and how Struts’modules works together. In addition, the java object persistence technology principle and the hibernate object relational mapping frame realization mechanism and the work principle are studied. On the basis of struts and the hibernate framework, one lightweight J2EE framework of open source technology is proposed, which has been applied to opening up sanitation management system project in Chongqing Banan area, and have proved to be a fast to develop, stable and expandable enterprise level application。Finally, this author analyses the benefit and the risk when any enterprise makes use of ths Open Source Technology, and sums up the research works and points out the更多还原
