如何阻止Jframe窃取键盘输入

import java.awt.KeyboardFocusManager;
import java.awt.KeyEventDispatcher;
import java.awt.event.KeyEvent;

public class KeyboardInputInterceptor implements KeyEventDispatcher {
    @Override
    public boolean dispatchKeyEvent(KeyEvent e) {
        if (e.getSource() instanceof javax.swing.JFrame) {
            // 阻止JFrame窃取键盘输入
            e.consume();
        }
        // 其他处理逻辑...
        return false;
    }

    public static void main(String[] args) {
        KeyboardInputInterceptor interceptor = new KeyboardInputInterceptor();
        KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(interceptor);

        // 创建并显示JFrame
        javax.swing.JFrame frame = new javax.swing.JFrame("My JFrame");
        frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
        frame.setSize(300, 200);
        frame.setVisible(true);
    }
}
