这里说的是在JPanel中进行监听。直接来看代码比较直观：

// 首先我们要定义一个类来继承JPanel类，并添加鼠标监听
public class MyPanel extends JPanel
        implements MouseListener, MouseMotionListener {

    public MyPanel() {

        // 添加鼠标响应
        this.addMouseListener(this);
        this.addMouseMotionListener(this);
    }

    // 根据提示，自动生成了要实现的各种鼠标事件通知函数
    // 常用的都有
    @Override
    public void mouseClicked(MouseEvent mouseEvent) {}
    @Override
    public void mousePressed(MouseEvent mouseEvent) {}
    @Override
    public void mouseReleased(MouseEvent mouseEvent) {}
    @Override
    public void mouseEntered(MouseEvent mouseEvent) {}
    @Override
    public void mouseExited(MouseEvent mouseEvent) {}
    @Override
    public void mouseDragged(MouseEvent mouseEvent) {}
    @Override
    public void mouseMoved(MouseEvent mouseEvent) {}
}
