摘　　要：Java反射机制是提高系统灵活性、可扩展性的重要技术,它使得软件系统具有自适应能力,并在运行时随外部环境的变化而改变自身,实现程序的动态演进。介绍了反射的概念和Java反射机制,根据基于O/R映射的数据持久层框架的设计方案,采用反射机制实现了域对象(Domain Object)信息的动态加载,并给出了具体实现方法实例。Java reflection mechanism is an important technology for improving system flexibility and expandability, which makes the software system self-adaptive and changes it, elf with the external environmental variation so as to realize the dynamic evolution of the program. The concept and mechanism of reflection are introduced, and the design approach for the Framework of Persistence Data Tier based on O/R mapping is taken as the basis to realize dynamic loading and storing on domain object with reflection mechanism, and the concrete realizing method example is put forward as well.
