Java 将字节数组转成十六进制字符串，java十六进制,public stati

public static String getHexString(byte[] b) throws Exception {  String result = "";  for (int i=0; i < b.length; i++) {    result += Integer.toString( ( b[i] & 0xff ) + 0x100, 16).substring( 1 );  }  return result;}public static byte[] getByteArray(String hexString) {  return new BigInteger(hexString,16).toByteArray(); }//该片段来自于http://byrx.net
