随着互联网的迅速发展,Internet上的Web应用大量涌现.然而传统主要依靠管理人员人工配置和维护系统的方式由于不断变化的环境和需求而显得有所不足.本文在相关工作的基础上,提出一种基于软件体系结构构建自适应Web系统的技术方案,该方案具有非侵入式设计和自适应相关组件具有可恢复能力的特点.同时,本文也实现了一个自适应系统原型来说明这个方案及其效果. With the rapid development of the Internet, there have been a lot of Web applications on the Internet, however, the traditional methods rely mainly on the manual configuration and maintenance of managers due to the changing environment and the needs of the system.This paper, based on the related work, A technical scheme based on software architecture to construct an adaptive Web system with non-intrusive design and self-adaptive related components has recoverability.At the same time, this paper also implements an adaptive system prototype to illustrate this scheme and Its effect.
