以下3个方法能将byte[]转化成16进制字符串,可以任选一个
/* * * Convert byte[] to hex string.这里我们可以将byte转换成int,然后利用Integer.toHexString(int) *来转换成16进制字符串。 * @param src byte[] data * @return hex string */ public static String bytesToHexString(byte[] src){ StringBuilder stringBuilder = new StringBuilder(""); if (src == null || src.length <= 0) { return null; } for (int i = 0; i < src.length; i++) { int v = src[i] & 0xFF; String hv = Integer.toHexString(v); if (hv.length() < 2) { stringBuilder.append(0); } stringBuilder.append(hv); } return stringBuilder.toString(); } public static String bytes2HexString(byte[] b) { String ret = ""; for (int i = 0; i < b.length; i++) { String hex = Integer.toHexString(b[i] & 0xFF); if (hex.length() == 1) { hex = "0" + hex; } ret += hex; } return ret;} public static String toHex(byte[] buffer) { StringBuffer sb = new StringBuffer(buffer.length * 2); for (int i = 0; i < buffer.length; i++) { sb.append(Character.forDigit((buffer[i] & 240) >> 4, 16)); sb.append(Character.forDigit(buffer[i] & 15, 16)); } return sb.toString();}
