A Research And Implementation Of MVC-based JAVA Application Framework

An application framework is a reuseable design component which prescribes the system structure of application, explains dependency relationship, responsibility assigning and control flow between entire design and cooperating components, representing itself as methods among a group of abstract classes and their instances therefore providing context relationships to component reuseability. User defined methods are not called by user application codes but framework itself frequently. This mechanism is often called " Hollywood principle" or "Don't call us, we'll call you".So users can concern only business logic while needn't take communication among modules into account, thus both physical and mental power is saved, develop efficiency is increased greatly and the cost is decreased. A rather successful example for application framework is Document-View structure of MFC. C++ programmers can develop applications easely thanks to the framework. But such a framework is not offered in mainstream developing tools for JAVA. Codes for only a simple interface is offered by Jbuilder and even no such codes can be found in Eclipse. To develop a Java appllication, programmers have to design same framework and code repaetly by themselves. To improve it, a MVC-based JAVA application framework is designed and implemented in this paper.
