JFinalConfig 子類需要實(shí)現(xiàn)五個(gè)抽象方法，如下所示：

public class DemoConfigextends JFinalConfig

{ publicvoid configConstant(Constants me)

{} public void configRoute(Routesme) {} 

publicvoid configPlugin(Plugins me) {}

public void configInterceptor(Interceptors me) {}

public void configHandler(Handlersme) {}

}
