java（jdk1.4、jdk1.6）获取mac地址的方法（winxp、win2003、win7、linux）

项目是年代久远的了，用的是jdk1.4，登录验证需要加mac地址验证，而且是需要兼容主流平台的操作系统。

得，任务落到了咱的头上，啃之。

 

考虑到jdk1.4没有API取得mac地址，故使用系统命令cmd ipconfig /all  截取mac地址。但考虑到环境变量的改变有可能影响到 ipconfig命令的执行，而ipconfig.exe命令在操作

系统的路径是c:\windows\system32\ipconfig.我们只要获取到环境变量中windir的值，即c:\window

 

贴上该类，jdk1.4下，在winxp(包括虚拟机)、win2003(包括虚拟机)、win7(联想)均通过，linux和unix没测试。如有错误，欢迎指正。

再附上一个jdk1.6获取mac的方法，但这个方法没进行过不同操作系统的测试。

/** * jdk1.6下API获取mac地址 * @return */public static String getMAC() {Enumeration<NetworkInterface> el;String mac_s = "";try {el = NetworkInterface.getNetworkInterfaces();while (el.hasMoreElements()) {byte[] mac = el.nextElement().getHardwareAddress();if (mac == null)continue;mac_s = hexByte(mac[0]) + "-" + hexByte(mac[1]) + "-"+ hexByte(mac[2]) + "-" + hexByte(mac[3]) + "-"+ hexByte(mac[4]) + "-" + hexByte(mac[5]);System.out.println(mac_s);}} catch (SocketException e1) {e1.printStackTrace();}return mac_s;}
