十六进制字符串命令转化为byte数组

十六进制字符命令：03 03 00 00 1F 2D 8A

public static byte[] hexStrToBytes(String hexStr) {
        String[] hexs = splitString(hexStr);
        byte[] hexBytes = new byte[hexs.length];
        for (int i = 0; i < hexs.length; i++) {
            hexBytes[i] = hexToByte(hexs[i]);
        }
        return hexBytes;
    }

结果：
