signing which bases on the view layer, also the encapsulation of the custom tag and the compiled language for the basic interface of action are finished according to the request of the system. In this system, the business layer is a combo of single-example mode and IoC mode, so the compiled language for the common deputize and the encapsulation of the business logic interface have been realized. The realized mode that is applied to the framework design of the persistent layer is based on the framework of the persistent layer in existence, also the encapsulation of creating example for Session and the encapsulation of database for common use are realized. As a result, it will reduce the coupling, and a lot of temporary objects created in this process will be avoided.
Favorable expansibility and maintainability can be achieved in this system framework. This frame is not only applied to the systemic development but also can be applied to the most B/S system which bases on the frame of SSH in the field of J2EE.
