我只能想到两个选择：
1.重新启动应用程序,而不是最好的用户体验.
2.创建一个可以注册/注销组件的本地化管理器,在更改时,它将迭代所有组件并更改文本.

1和2都觉得尴尬.

其他信息：
目前,方向不是目标.
该应用程序被混淆.

例：

LocRes_en.properties：

    text1 = English text

LocRes_ja.properties

    text1 = Japanese text

ChangeLocale.java：

    import java.awt.EventQueue;
    import java.awt.FlowLayout;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.util.Locale;
    import java.util.ResourceBundle;

    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JLabel;

    public class ChangeLocale {

        private JFrame frame;

        public static void main(String[] args) {
            EventQueue.invokeLater(new Runnable() {
                public void run() {
                    try {
                        ChangeLocale window = new ChangeLocale();
                        window.frame.setVisible(true);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        }

        public ChangeLocale() {
            initialize();
        }

        private void initialize() {
            frame = new JFrame();
            frame.setBounds(100,100,450,300);
            frame.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
            FlowLayout flowLayout = new FlowLayout(FlowLayout.CENTER,5,5);
            frame.getContentPane().setLayout(flowLayout);

            JButton btnChangeLoc = new JButton("Change Locale");
            frame.getContentPane().add(btnChangeLoc);

            final JLabel lblLabel1 = new JLabel("New label");
            frame.getContentPane().add(lblLabel1);
            Locale.setDefault(new Locale("en"));
            ResourceBundle r = ResourceBundle.getBundle("LocRes");
            lblLabel1.setText(r.getString("text1"));

            btnChangeLoc.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    Locale.setDefault(new Locale("ja"));
                    ResourceBundle r = ResourceBundle.getBundle("LocRes");
                    // Manually iterate through all components :(
                    lblLabel1.setText(r.getString("text1"));
                    //
                }
            });
        }
    }
