J2SE实现windows下读取网卡的物理地址

这个例子使用了J2SE5.0的ProcessBuilder类执行外部的程序，相对于 Runtime.exec ,它更方便，可以设置环境变量等。

package com.kuaff.jdk5package;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

public class ProcessBuilderShow
{
public static List getPhysicalAddress()
{
      Process p = null;
      //物理网卡列表
      List address = new ArrayList();

      try
      {
         //执行ipconfig /all命令
         p = new ProcessBuilder("ipconfig", "/all").start();
      }
      catch (IOException e)
      {
         return  address;
      }
      byte[] b = new byte[1024];
      StringBuffer sb = new StringBuffer();
      //读取进程输出值
      InputStream in = p.getInputStream();
      try
      {
         while (in.read(b)>0)
         {
            sb.append(new String(b));
         }
      }
      catch (IOException e1)
      {
      }
      finally
      {
         try
         {
            in.close();
         }
         catch (IOException e2)
         {
         }
      }
      //以下分析输出值，得到物理网卡
      String rtValue = sb.substring(0);
      int i = rtValue.indexOf("Physical Address. . . . . . . . . :");
      while(i>0)
      {
         rtValue = rtValue.substring(i + "Physical Address. . . . . . . . . :".length());
         address.add(rtValue.substring(0,18));
         i = rtValue.indexOf("Physical Address. . . . . . . . . :");

}

      return address;

}
public static void main(String[] args)
{
      List address = ProcessBuilderShow.getPhysicalAddress();
      for(String add:address)
      {
         System.out.printf("物理网卡地址:%s%n", add);
      }
}
}
