【摘要】 <正> 1.引言中间件处理的是复杂的分布式应用问题,常常面对变化的运行环境和不同的用户需求。当前的基于对象的中间件,无论CORBA,DCOM还是Java RMI基本上都采用了黑箱抽象的设计原则,即对外呈现其功能而隐藏其内部实现,这使这些中间件缺少必要的灵活性和适应性。更多还原

【Abstract】 Current middlewares are limited in their flexibility and adaptabiliy in face of changing environment and different user requirements. Applying the reflection technology to the middleware design has become a new research field. In this psper,the processing of middleware and the reflection mechanism are compared,and then the reflecive view of middleware is yielded. Based on this,the idea of employing binding reification reflective model in middleware design is proposed,and the design principles of a reflective middleware prototype named RECOM are deduced. Whereafter,this paper details RECOM’ s implementation about its binding factories,refletive structure,and configurable reflective layers.更多还原
