　　随着 Internet 的发展、应用需求的日趋复杂,传统浏览器-服务器模式下的瘦客户端不再能够满足应用这种需求,进而促使了具有良好用户体验、可以有效利用本地存储计算资源的富客户端应用的出现。富客户端应用遵循“模型-视图-控制器(model-view-controller,简称 MVC)”体系结构风格,运行在客户端的软、硬件运行环境中。随着移动设备硬件、浏览器软件的发展,不同富客户端运行环境能力差异很大。另一方面,因为 Internet 的开放性、动态性,富客户端应用开发人员不可能预知其运行环境的特点。因此,富客户端不可避免地面临异构运行环境造成的适应性问题。提出一种富客户端运行环境自适应中间件,可提供一个符合富客户端应用体系结构风格的 MVC 构件模型,并利用构件的数据模型、控制器与视图这3部分,有针对性地处理富客户端存储环境、计算环境以及显示环境中的适应性问题,提供相应的自适应解决方案。提出的自适应中间件封装了以上构件模型与自适应机制,保证运行于中间件上的富客户端可以适应运行环境,合理、高效地利用运行环境中的存储、计算以及显示资源。

As the Internet has rapidly grown, rich Internet application (RIA) has become the mainstream application since it uses local storage and computes resources more effectively and therefore has better user experience. The client-side of RIA, i.e. rich client, can be thought of a sub-application which adopts“model-view-controller”architecture style and runs on the client-side runtime. Along with the development of mobile device and web browser, there are large differences among different client-side runtimes. However, rich client cannot predict the characteristics of its runtime due to the open nature of the Internet, and therefore suffers from the heterogeneous runtimes. This paper proposes a rich client middleware for runtime self-adaption. The middleware provides a MVC component model and decompose the problem of heterogeneous runtimes into three sub-problems:The problem of heterogeneous storage runtimes, the problem of heterogeneous computation runtimes and the problem of heterogeneous display runtimes. The middleware encapsulates a series of common self-adaption services which solve the problems correspondingly.
