在运行时更改语言环境并在之后立即更新GUI文本？

Question

我正在编写一个可通过单击按钮更改GUI语言的程序。我正在使用ResourceBundle来获取键值对。但是当我更改语言环境GUI语言时，不会改变...

有什么方法可以执行而无需重新启动程序？

public class Language extends JPanel{

    public JButton Back = new JButton("Done");
    public static JComboBox<Locale> LangCBox;
    private static ResourceBundle message = ResourceBundle.getBundle("messagesBundle",Language.getDefaultLocale());

    private Locale locale;

    public Language()
    {
        langPanel = new JPanel();
        langPanel.setLayout(null);
        this.setLayout(new BorderLayout());
        Back.setBounds(200, 250, 100, 20);
        Back.addActionListener(listen);
        langPanel.add(Back,"Center");
        LangCBox = new JComboBox();             
        LangCBox.addItem(new Locale("ko","KR"));
        LangCBox.addItem(new Locale("en","US"));
        LangCBox.addItem(new Locale("zh","CN"));
        LangCBox.addItemListener(itemEvent -> SetLanguage());
        langPanel.add(LangCBox);
        LangCBox.setBounds(150, 150, 200, 20);
        this.add(langPanel);
    }

    ActionListener listen = new ActionListener()
            {

                @Override
                public void actionPerformed(ActionEvent e) {
                    // TODO Auto-generated method stub
                    if(e.getSource()==Back)
                    {
                        Application.MyCard.card.show(Application.mainPanel,"LogIn");
                    }

                }

            };


    public void SetLanguage()
    {
        ResourceBundle.clearCache();
        Locale locale = LangCBox.getItemAt(LangCBox.getSelectedIndex());
        message = ResourceBundle.getBundle("Messagesbundle",locale);
        validate();

    }

    public static String getString(String key)
    {
        return message.getString(key);
    }

}
