如何在JFrame中获取对其上出现MouseEvent的元素的引用

import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class MainFrame extends JFrame {
    public MainFrame() {
        // 设置JFrame的属性和布局
        setTitle("获取鼠标点击元素的引用");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        // 添加MouseListener
        addMouseListener(new MouseListener() {
            @Override
            public void mouseClicked(MouseEvent e) {
                // 获取鼠标点击的坐标
                int x = e.getX();
                int y = e.getY();

                // 获取鼠标点击位置的组件
                Component component = SwingUtilities.getDeepestComponentAt(getContentPane(), x, y);

                // 打印组件的引用
                System.out.println("Clicked Component: " + component);
            }

            @Override
            public void mousePressed(MouseEvent e) {}

            @Override
            public void mouseReleased(MouseEvent e) {}

            @Override
            public void mouseEntered(MouseEvent e) {}

            @Override
            public void mouseExited(MouseEvent e) {}
        });
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            MainFrame frame = new MainFrame();
            frame.setVisible(true);
        });
    }
}
