十进制Ip转换为Ip

object Int2IP {
   def int2IP(ipInt: Long): String =  {
     val sb: StringBuilder = new StringBuilder
     sb.append(ipInt & 0xFF).append(".")
     sb.append((ipInt >> 8) & 0xFF).append(".")
     sb.append((ipInt >> 16) & 0xFF).append(".")
     sb.append((ipInt >> 24) & 0xFF)
     return sb.toString
   }
