java 代碼

JSONObject jsonObject = new JSONObject();
		jsonObject.put("name1", "hao1");
		jsonObject.put("name2", "hao2");
		jsonObject.put("name2", "hao2");
		String string = jsonObject.toString();
		System.out.println(string);
		
		Map<EncodeHintType,Object> hints=new HashMap<EncodeHintType,Object>();
		hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");
		
		BitMatrix bitMarix=new MultiFormatWriter().encode(string, BarcodeFormat.QR_CODE, 200, 200,hints);
	
		String path="/005_STS_ENV/";
		String name="eq.jpg";
		
		Path path2 = FileSystems.getDefault().getPath(path, name);
		
		MatrixToImageWriter.writeToPath(bitMarix, "jpg", path2);
		System.out.println("ok");
