摘要
随着企业级开发平台诸如J2EE的普及和发展,越来越多的企业应用采用了这些技术作为快速开发平台,但是,这些应用也面临着一些困扰,特别是性能问题。这主要是由这些系统的分布性、复杂性和数据无关性引起的。文中以一个基于J2EE的MIS的开发实践为背景,讨论了这些问题,并提出了改善系统的设计,使用数据缓存技术和优化数据访问等来避免性能瓶颈的出现,在实际的应用中提高了B/S系统的性能,最后提供了这些方法应用效果的测试数据。
With the popularization and development of enterprise platform such as J2EE, more and more enterprise applications apply thee technologies and take them as a solution for the development of platform. Meanwhile, it also meets some problems for these applications especially the performance issues. It is mainly because of the distribution, complexity and data - insensitive of these applications. On the basis of the development practice of a J2EE- based MIS, discusses a series of approaches to avoid and solve the bottleneck of performance from three aspects, including improve system design, use of data cache technologies and optimization of data access. A realistic example that is supposed to happen how these approaches improve performance on B/S system, then shows the applied effect of these approaches with testing data.
