我在java中使用ipconfig/all命令和正则表达式来查找MAC地址。
我在Physical Address命令的输出中搜索ipconfig/all。
但问题是我希望正则表达式适用于不同的语言环境，即它可以找到任何语言环境的物理地址。
提前致谢。

选项1：
您可以使用这样的正则表达式（英语，法语，西班牙语）：
/(Physical Address|Adresse Physique|Direccion fisica)/
稍后检查您正在使用的语言环境，并因此更新您的正则表达式。
选项2：
直接使用Java（JDK 1.6）获取MAC地址
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class MacAddress {
public static void main(String[] args) {
try {
//InetAddress address = InetAddress.getLocalHost();
InetAddress address = InetAddress.getByName("192.168.0.158");
/*
* Get NetworkInterface for the current host and then read the
* hardware address.
*/
NetworkInterface ni = NetworkInterface.getByInetAddress(address);
if (ni != null) {
byte[] mac = ni.getHardwareAddress();
if (mac != null) {
/*
* Extract each array of mac address and convert it to hexa with the
* following format 08-00-27-DC-4A-9E.
*/
for (int i = 0; i < mac.length; i++) {
System.out.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
}
} else {
System.out.println("Address doesn't exist or is not accessible.");
}
} else {
System.out.println("Network Interface for the specified address is not found.");
}
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e) {
e.printStackTrace();
}
}
}

不是搜索“物理地址”或其他任何本地化版本（每次需要支持新语言时都需要添加本地化版本），而只需编写一个正则表达式来查找MAC解决问题。
由于我们知道典型的MAC地址由六个分组组成，每个分组包含两个十六进制数字，以冒号，句号或短划线分隔，以下正则表达式将执行此操作：
([a-fA-F0-9]{2}[:\-\.]){5}[a-fA-F0-9]{2}
说明： （两个十六进制数字后跟一个冒号：重复5次）（最后两个十六进制数字）

这是我运行ipconfig /all时得到的结果：

正如你所看到的，寻找字符串“Physical Address”是徒劳的，因为没有一个。但请注意，Windows有自己的MAC地址格式 - 用连字符（字母部分大写）分隔每两个十六进制数字。所以，寻找正则表达式：
([0-9A-F]{2}-){5}[0-9A-F]{2}
会为您提供您正在寻找的MAC地址。
警告：许多计算机都有多个网络接口（有线和wifi，各种VPN等），因此输出中可能有多个MAC。

注意某些计算机，特别是HP / Compaq MAC地址应该可以从
访问Process pcs = Runtime.getRuntime().exec("wmic bios");
如果是BIOS定制的（Largiest Company）那么这个数据应该可以通过使用JNI / JNA（大量的VB / C＃脚本）访问
