利用zxing中jse开发包。

public static void main(String[] args) throws WriterException {

		String text = "hello, world !";

		Hashtable<EncodeHintType, String> hints = new Hashtable<EncodeHintType, String>();
		hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");
//		hints.put(EncodeHintType.MARGIN, "5");
		
		BitMatrix matrix = new MultiFormatWriter().encode(text, BarcodeFormat.QR_CODE, 200, 200, hints);

		File file = new File("qrcodeImage.png");

		try {

			MatrixToImageWriter.writeToFile(matrix, "png", file);
//			MatrixToImageWriter.toBufferedImage(matrix);

		} catch (IOException e) {

			e.printStackTrace();

		}
	}
