JDK1.6 获取操作系统IP地址及对应物理mac地址

import java.net.InetAddress;

import java.net.NetworkInterface;

import java.net.SocketException;

import java.util.Enumeration;

public class OSInfo {

public static void listIPMac() throws SocketException{

//首先获取到机器的所有网络接口

Enumeration<NetworkInterface> nis = NetworkInterface.getNetworkInterfaces();

NetworkInterface ni = null;

//网卡的物理mac地址二进制格式

byte[] macbyte = null;

//网卡的物理mac地址

String mac = null;

//遍历所有的网络接口

while(nis.hasMoreElements()){

ni = nis.nextElement();

//当不是回环网卡，并且启动，并且不是虚拟网卡

if(!ni.isLoopback() && ni.isUp() && !ni.isVirtual()){

macbyte = ni.getHardwareAddress();

//把二进制格式化成十六进制

mac = bytesToHexString(macbyte, macbyte.length);

Enumeration<InetAddress> ias = ni.getInetAddresses();

InetAddress ia = null;

while(ias.hasMoreElements()){

ia = ias.nextElement();

//不是 127.0.0.1 回环IP

if(!ia.isLoopbackAddress()){

System.out.println(ia.getHostAddress()+" = " + mac.toUpperCase());

}

}

}

}

}

/*

* 二进制转十六进制

*/

public static String bytesToHexString(byte[] src, int length) {

StringBuilder stringBuilder = new StringBuilder("");

if (src == null || src.length <= 0) {

return null;

}

for (int i = 0; i < length; i++) {

int v = src[i] & 0xFF;

String hv = Integer.toHexString(v);

if (hv.length() < 2) {

stringBuilder.append(0);

}

stringBuilder.append(hv);

}

return stringBuilder.toString();

}

public static void main(String[] args) {

try {

} catch (SocketException e) {

}

}

}

运行结果：

2001:0:4137:9e76:3804:5134:2249:d190 = 00000000000000e0

fe80:0:0:0:3804:5134:2249:d190%11 = 00000000000000e0

fe80:0:0:0:b8c8:25a3:8cb6:a0b7%13 = 0015af5*****

192.168.1.101 = 0015af5*****
