base64转16进制

物联网开发中,通过nb-iot发布过来的数据很多都是base64的数据,我们需要进行转换16进制后续转换10进制加以显示。以下提供base64转16进制方法。代码如下:

原数据:

/4YAAAAFAAB1fDAwMDB8AAAAAAAAAAAAAAB8AAAAAAAAAAAAAHwAAAAAAAAAAAAAfAHzfAB8AAAAAHwAAA==
 private static final char[] DIGITS
            = {'0', '1', '2', '3', '4', '5', '6', '7',
            '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};

    public static final String toHex(byte[] data) {
        final StringBuffer sb = new StringBuffer(data.length * 2);
        for (int i = 0; i < data.length; i++) {
            sb.append(DIGITS[(data[i] >>> 4) & 0x0F]);
            sb.append(DIGITS[data[i] & 0x0F]);
        }
        return sb.toString();
    }

通过方法转换后:
