Instantiate an FXMLLoader and use an instance load method rather than a class static load method. You can then retrieve the controller instance from the loader instance.
实例化 FXMLLoader 并使用实例加载方法而不是类静态加载方法。然后，您可以从加载程序实例中检索控制器实例。
FXMLLoader loader = new FXMLLoader(
getClass().getResource(
"customerDialog.fxml"
)
);
Pane pane = (Pane) loader.load();
CustomerDialogController controller =
loader.<CustomerDialogController>getController();
controller.initData(customer);
