	public static void main(String[] args) throws IOException {
		String docUploadPath = "D:\\home\\gg.docx";
		File refereeFile = new File(docUploadPath);
		byte[] refereeFileOriginalBytes = FileUtils.readFileToByteArray(refereeFile);
		byte[] refereeFileBase64Bytes = Base64.encodeBase64(refereeFileOriginalBytes);
		String UpFile = new String(refereeFileBase64Bytes, "UTF-8");
		System.out.println(UpFile);
