一步一步教你用java生成二维码

Image image

= src.getScaledInstance(width, height,

Image.SCALE_SMOOTH);

BufferedImage tag = new BufferedImage(width, height,

BufferedImage.TYPE_INT_RGB);

Graphics g = tag.getGraphics();

g.drawImage(image, 0, 0, null); // 绘制缩小后的图 g.dispose(); src = image;

} // 插入LOGO

Graphics2D

graph = source.createGraphics(); int x =

(QRCODE_SIZE - width) / 2; int y =

(QRCODE_SIZE - height) / 2;

graph.drawImage(src, x, y, width, height, null);

Shape shape

= new RoundRectangle2D.Float(x, y, width, width, 6, 6);

graph.setStroke(new BasicStroke(3f));

graph.draw(shape);

graph.dispose(); }
