java - FXML 加载异常未指定资源

Question

我开始使用 SceneBuilder 和 JetBrains IDE 构建程序，我想使程序国际化，所以我制作了一个属性文件。在 SceneBuilder 上一切正常，但是当我尝试使用 JetBrains 运行该程序时，出现此异常

这是我目前的代码

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setScene(new Scene(root, 1200, 1000));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

FXML 文件:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.geometry.Insets?>
<?import javafx.scene.Cursor?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.HBox?>

<BorderPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
   <top>
      <HBox spacing="20.0" BorderPane.alignment="CENTER">
         <children>
            <Button mnemonicParsing="false" text="%newWorkButton">
               <cursor>
                  <Cursor fx:constant="CLOSED_HAND" />
               </cursor></Button>
            <Button mnemonicParsing="false" text="%dbButton" />
         </children>
         <padding>
            <Insets bottom="15.0" left="15.0" right="15.0" top="15.0" />
         </padding>
         <BorderPane.margin>
            <Insets />
         </BorderPane.margin>
      </HBox>
   </top>
</BorderPane>

我知道问题是在尝试加载属性文件时发生的，但为什么它在 SceneBuilder 中可以正常工作，而当我尝试运行它时却不起作用？

PS:问题发生在 %newWorkButton 或 %dbButton 出现时，因为那是它使用属性文件的部分。

我正在回答我自己的帖子，因为我几天前就找到了答案。正如您在 Main 中看到的那样，我让这一行加载了 fxml:

Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"))

但是因为我使用的是属性文件，所以我也需要加载它，所以这就是我所做的:

 ResourceBundle resources = ResourceBundle.getBundle("Language/lang_pt");;

 Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"),resources);
