產生二維碼，二維碼產生器

產生二維碼，二維碼產生器

一、利用google提供的的zxing產生不包含logo的二維碼

public static void main(String[] args){try {//二維碼跳轉內容String contet = "http://izhongwei.github.io/blog/index.html";//二維碼產生路徑String path = "E:";MultiFormatWriter multiFormatWriter = new MultiFormatWriter();Map hints = new HashMap();hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");BitMatrix bitMatrix = multiFormatWriter.encode(contet, BarcodeFormat.QR_CODE, 400, 400, hints);// 產生二維碼尺寸大小File file = new File(path,"test.jpg");//產生二維碼後的圖片路徑和名稱ImageWrite.writeToFile(bitMatrix, "jpg", file);//需要ImageWrite類產生圖片System.out.println("二維碼已經產生");} catch (Exception e) {e.printStackTrace();}}

　　運行main方法後在：

二、利用google的zxing產生包含logo的二維碼
