我有javafx菜单，我想切换到另一个窗口。当我使用Java-8时，一切正常，但是现在我切换到javafx-11和java-11，无法切换。 切换代码
AnchorPane pane = FXMLLoader.load(getClass().getResource("/main/main.fxml"), resources);
我正在搜索Internet和stackoverflow，并尝试了以下操作 1.在Inteliij想法中，我添加了所有模块和库，并在Project Structure中应用了更改。 2.我添加到src包module-info.java 3.我检查了我尝试加载的fxml是否不包含任何错误或未读取的ID。 4.我检查了我要加载的控制器和fxml的名称
module-info.java的代码
module duno {
requires javafx.fxml;
requires javafx.controls;
requires java.logging;
requires javafx.web;
opens main;
}
我正在调用Controller以获得“设置”窗口的方法的代码
@FXML
void goto_settings(ActionEvent event) {
try {
ResourceBundle resources;
switch(settings.getLanguage().get(settings.getSelectedLanguage())) {
case "Czech":
resources = ResourceBundle.getBundle("/bundles/LangBundle_cz");
break;
default:
resources = ResourceBundle.getBundle("/bundles/LangBundle_en");
}
AnchorPane pane = load(getClass().getResource("/settings/settings.fxml"), resources);
rootpane.getChildren().setAll(pane);
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);

不要介意输出中的英语，它只是应用程序中使用的语言
答案 0 :(得分：0)
我自己弄清楚了。 这是我继续的方法。 我多次读取该错误，然后我需要导出一些内容。因此，我发现模块信息已将某些内容导出到某些内容。因此，我将导出设置添加到javafx.fxml。 我无法访问设置的另一个问题，因为rootpane是私有的，并且设置没有打开。所以我尝试了开放设置；它有效：）
所以这是最终版本
module duno {
requires javafx.fxml;
requires javafx.controls;
requires java.logging;
requires javafx.web;
exports settings to javafx.fxml;
opens main;
opens settings;
}
我希望它对以后遇到相同错误的人有所帮助
