java - Java 中的国际化错误

Question

我正在学习Java，我们的老师告诉我们一个netbeans中的国际化示例，他为不同的语言创建了三个属性文件(在netbeans中你可以轻松创建属性文件)，所以我在家里使用eclipse尝试这个，现在我创建了3 个属性文件与我们老师创建的文件夹完全相同(.java 文件所在的文件夹)我做了与他相同的代码，但我得到了一个错误，然后我尝试在netbeans中运行netbeans项目(我从老师的计算机上获取它)，它给了我同样的错误，现在我认为编码很好，但是有属性文件中存在一些错误

这是代码

package example;


import java.awt.EventQueue;
import java.awt.Font;
import javax.swing.ButtonGroup;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.border.EmptyBorder;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import java.util.Locale;
import java.util.ResourceBundle;


public class MyFrame extends JFrame {

    private static final long serialVersionUID = 1L;
    /**
     * 
     */
    private JPanel contentPane;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    MyFrame frame = new MyFrame();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    /**
     * Create the frame.
     */
    public MyFrame() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 156);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);

        final JLabel lbl = new JLabel("My Internationalization Example");
        lbl.setFont(new Font("Tahoma", Font.PLAIN, 14));
        lbl.setBounds(106, 21, 204, 17);
        contentPane.add(lbl);

        JRadioButton rdbtnEnglish = new JRadioButton("English");
        rdbtnEnglish.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {

                Locale lang = new Locale("en" , "US");
                ResourceBundle message = ResourceBundle.getBundle("src/example/MessageBundle_en_US", lang);
                lbl.setText(message.getString("LangValue"));
            }
        });
        rdbtnEnglish.setBounds(42, 59, 109, 23);
        contentPane.add(rdbtnEnglish);

        JRadioButton rdbtnFrance = new JRadioButton("France");
        rdbtnFrance.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {

                    Locale lang = new Locale("fr" , "FR");
                    ResourceBundle message = ResourceBundle.getBundle("src/example/MessageBundle_fr_FR", lang);
                    lbl.setText(message.getString("LangValue"));
                }
        });
        rdbtnFrance.setBounds(153, 59, 142, 23);
        contentPane.add(rdbtnFrance);

        JRadioButton rdbtnGerman = new JRadioButton("German");
        rdbtnGerman.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {

                Locale lang = new Locale("de" , "DE");
                ResourceBundle message = ResourceBundle.getBundle("src/example/MessageBundle_de_DE", lang);
                lbl.setText(message.getString("LangValue"));
            }
        });
        rdbtnGerman.setBounds(297, 59, 109, 23);
        contentPane.add(rdbtnGerman);


        ButtonGroup myGroup = new ButtonGroup();
        myGroup.add(rdbtnEnglish);
        myGroup.add(rdbtnFrance);
        myGroup.add(rdbtnGerman);

        rdbtnEnglish.setSelected(true);




    }

}

这是所有三个属性文件中的内容

MessageBundle_en_US.properties

LangValue = My Internationalization Example

MessageBundle_de_DE.properties

LangValue = Meine Internationalisierung Beispiel

MessageBundle_fr_FR.properties

LangValue = Mon internationalisation Exemple

现在这是我的属性和java文件所在的文件夹

D:\Documents\Work\Eclipse\InternationalizationExample\src\example

这是一个屏幕截图，可以更好地查看

现在，当我运行时，我的程序会运行，但是当我选择选项时，它会给我这个错误，我在谷歌上搜索了整整3个小时，并尝试了从更改位置、文件夹等所有内容

当我单击另一个选项 BOOM 时，出现错误

错误是

为了获得更多帮助，我已将整个 Eclipse 项目上传到此 rar 中

Answer 1

将 getBundle 语句更改为:

ResourceBundle message = ResourceBundle.getBundle("src/example/MessageBundle_en_US", lang);

至:

ResourceBundle message = ResourceBundle.getBundle("example/MessageBundle", lang);
