错误说：
because module HLC does not export VideoClub.controllers to module javafx.fxml
所以这是您需要打开 fxml 的包。
添加到您的模块信息：
opens VideoClub.controllers to javafx.fxml;

错误说：
because module HLC does not export VideoClub.controllers to module javafx.fxml
所以这是您需要打开 fxml 的包。
添加到您的模块信息：
opens VideoClub.controllers to javafx.fxml;
