Research Of Technology Of Adaptive Component Based On Reflection

As the development of Internet application,software compute environment is changing from centralized to open and dynamic platform,and will instead by service-oriented compute mode.So traditional software component technology is hard to deal with these changings.The paper researches about technology of flexible and adaptive software component based on the theory of reflection.The paper researches some key contents as following:The first is the research about the component's self-adaptation technology. The paper points out a reflective model of component on the basis of technology of reflection,designs control and dependence relationship between different parts of component.So it can adjust itself while running,and improve flexibility and adaptive capablity of software.The second is the way of software integration based on components on Internet.The integration frame not only implements components composition platform based on meta model and software architecture,but also service-oriented software integration.The third is the research about reconfiguration mechanism of software integration frame.The paper proposers reflective structure of integration frame.Drawing lessons from open-implement,users can select components or services to composit system according to functional and performance requirements in different domain.So it can help achieve high quality of software integration.At last, this paper takes the teacher data center system for example.Use component based on reflection mechanism to satisfy dynamic operating environment as well as various users' demands.Then achieve system's integration.These validate that the technology is rational,available and effective.
