LoadException при попытке загрузить новое окно fxml

0 голосов
/ 10 мая 2019

У меня есть меню javafx, я хочу перейти в другое окно.Когда я использовал Java-8, все работало, но теперь я переключился на javafx-11 и java-11 и не могу переключиться.Код переключения 

AnchorPane pane = FXMLLoader.load(getClass().getResource("/main/main.fxml"), resources);

Я искал Интернет и stackoverflow и попытался выполнить следующее. 1. В идее Inteliij я добавил все модули и библиотеки и применил изменения в структуре проекта.2. Я добавил в пакет src module-info.java 3. Я проверил, не содержит ли fxml, который я пытаюсь загрузить, какие-либо ошибки или unsed идентификаторы.4. Я проверил имена контроллеров и fxmls, которые я пытаюсь загрузить

Код модуля-info.java 

module duno {
    requires javafx.fxml;
    requires javafx.controls;
    requires java.logging;
    requires javafx.web;

    opens main;
}

Код метода из контроллера, который я вызываю, чтобы получитьОкно настроек 

    @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) {

Не обращайте внимания на английский в выводе, это просто язык, используемый в приложении

Я понял это самостоятельно.Вот как я поступил.Я читаю ошибку несколько раз, а потом мне хоть что-то нужно экспортировать.Итак, я обнаружил, что информация модуля экспортирует что-то во что-то.Поэтому я добавил настройки экспорта в javafx.fxml.Другая проблема в том, что я не смог получить доступ к настройкам, потому что корневая панель была закрытой, а настройки не были открыты.Поэтому я попытался открыть настройки;и это работает:)

Так вот окончательная версия 

module duno {
requires javafx.fxml;
requires javafx.controls;
requires java.logging;
requires javafx.web;
exports settings to javafx.fxml;

opens main;
opens settings;

}

Я надеюсь, что это поможет кому-то в будущем с той же ошибкой
