java获取ip地址和Mac地址

public class GetMacAddress extends HttpServlet{

public void doGet(HttpServletRequest request, HttpServletResponse response)

    在JAVA中有时候会需要定位到某台电脑，而通过IP定位显然是不行的，有一种解决方案是通过定位到电脑的物理地址来定位电脑，这是本文要介绍的内容。    1. PhysicalAddressUtilpackage com.jetsum.web.util;import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.logging.Level;

import java.util.logging.Logger;import test.Test;

public class PhysicalAddress

{

 public static String getMACAddress()

 {  String address = "";

  String os = System.getProperty("os.name");

  if (os != null)

  {

   if (os.startsWith("Windows"))

   {

    try

    {

     ProcessBuilder pb = new ProcessBuilder("ipconfig", "/all");

     Process p = pb.start();

     BufferedReader br = new BufferedReader(

       new InputStreamReader(p.getInputStream()));

     String line;

     while ((line = br.readLine()) != null)

     {

      if (line.indexOf("Physical Address") != -1)

      {

       int index = line.indexOf(":");

       address = line.substring(index + 1);

       break;

      }

     }

     br.close();

     return address.trim();

    } catch (IOException e)

    {    }

   } else if (os.startsWith("Linux"))

   {

    try

    {

     ProcessBuilder pb = new ProcessBuilder("ifconfig");

     Process p = pb.start();

     BufferedReader br = new BufferedReader(

       new InputStreamReader(p.getInputStream()));

     String line;

     while ((line = br.readLine()) != null)

     {

      int index = line.indexOf("硬件地址");

      if (index != -1)

      {

       address = line.substring(index + 4);

       break;

      }

     }

     br.close();

     return address.trim();

    } catch (IOException ex)

    {

     Logger.getLogger(Test.class.getName()).log(Level.SEVERE,

       null, ex);

    }   }

  }

  return address;

 }

}

    2.使用String address = PhysicalAddressUtil.getMACAddress() ;
