示例代码

String data = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
BigInteger sum = BigInteger.ZERO;
        String[] split = StrUtil.split(data, 2);
        for (String s : split) {
            BigInteger num = new BigInteger(s, 16);
            sum = sum.add(num);
        }
String sumResult = sum.toString(16).toUpperCase();
