从 7.* 迁移 wicket 8.*，AbstractRequestCycleListener 上的 onRequestHandlerResolved() 方法有问题

Question

我正在 Wicket 8.* 迁移，当我在 IRequestCycleListener 方法转换下的 onRequestHandlerResolved() 上挣扎时。

根据我的代码 wicket 7.15.0 中的逻辑结构

public class MyRequestCycleListener extends AbstractRequestCycleListener{
//All methods override here
    @Override
    public void onRequestHandlerResolved(RequestCycle cycle, IRequestHandler handler) {
       if (handler instanceof ListenerInterfaceRequestHandler) {
           ListenerInterfaceRequestHandler requestHandler = (ListenerInterfaceRequestHandler) handler;
           if (requestHandler.getListenerInterface().getListenerInterfaceClass().isAssignableFrom(         IFormSubmitListener.class)) {
                 //here made some login as well as every onSubmit
           }
       }
    }
}

随着 wicket 8.* 的变化 AbstractRequestCycleListener class 转换为 IRequestCycleListener 接口 ListenerInterfaceRequestHandler 重命名为 ListenerRequestHandler 弃用 RequestListenerInterface 并且 IFormSubmitListener 也会出错

如何在 wicket 8.9.0 上将代码转换为迁移？

应该是这样的：

public class MyRequestCycleListener implements IRequestCycleListener{

    @Override
    public void onRequestHandlerResolved(RequestCycle cycle, IRequestHandler handler) {
        if (handler instanceof ListenerRequestHandler) {
             ListenerRequestHandler requestHandler = (ListenerRequestHandler) handler;

            if (requestHandler.getComponent() instanceof Form) {
                  //here made some login as well as every onSubmit
                  Form form = (Form) requestHandler.getComponent();
            }
        }
    }
}
