Java 在JTextField的边缘是否有消除模糊的方法？

我正在圆化我的JTextField，但在圆化字段后，边缘模糊，看起来不专业

这是我用来取整JTextField的代码。我正在扩展JTextField并更改paintComponenet值

 //Rouding the field
     protected void paintComponent(Graphics g) {
         g.setColor(getBackground());
         g.fillRoundRect(0, 0, getWidth()-1, getHeight()-1, 15, 15);
         super.paintComponent(g);
    }
    protected void paintBorder(Graphics g) {
         g.setColor(getForeground());
         g.drawRoundRect(0, 0, getWidth()-1, getHeight()-1, 15, 15);
    }
    public boolean contains(int x, int y) {
         if (shape == null || !shape.getBounds().equals(getBounds())) {
             shape = new RoundRectangle2D.Float(0, 0, getWidth()-1, getHeight()-1, 15, 15);
         }
         return shape.contains(x, y);
    }

在绘制方法中，可以尝试对图形使用抗锯齿

您可以在单独的图形对象上设置绘制属性：

Graphics2D g2d = (Graphics2D)g.create();
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
// add painting logic
g2d.dispose();
