在JList上使用MouseMotionListener来检测鼠标何时输入，然后调用
setCursor将其转换为
HAND_CURSOR。
样例代码：
final JList list = new JList(new String[] {"a","b","c"});list.addMouseMotionListener(new MouseMotionListener() { @Override public void mouseMoved(MouseEvent e) { final int x = e.getX(); final int y = e.getY(); // only display a hand if the cursor is over the items final Rectangle cellBounds = list.getCellBounds(0, list.getModel().getSize() - 1); if (cellBounds != null && cellBounds.contains(x, y)) { list.setCursor(new Cursor(Cursor.HAND_CURSOR)); } else { list.setCursor(new Cursor(Cursor.DEFAULT_CURSOR)); } } @Override public void mouseDragged(MouseEvent e) { }});
