java根据本地IP获取mac地址的方法

java根据本地IP获取mac地址的方法

本文实例为大家分享了java根据本地IP获取mac地址的具体代码，供大家参考，具体内容如下

import java.net.InetAddress;

import java.net.NetworkInterface;

import java.net.SocketException;

import java.net.UnknownHostException;

public class MacAddress {

/**

* @param args

* @throws UnknownHostException

* @throws SocketException

*/

public static void main(String[] args) throws UnknownHostException, SocketException {

InetAddress ia = InetAddress.getLocalHost();

System.out.println(ia);

getLocalMac(ia);

}

private static void getLocalMac(InetAddress ia) throws SocketException {

// TODO Auto-generated method stub

//获取网卡，获取地址

byte[] mac = NetworkInterface.getByInetAddress(ia).getHardwareAddress();

System.out.println("mac数组长度："+mac.length);

StringBuffer sb = new StringBuffer("");

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

if(i!=0) {

sb.append("-");

}

//字节转换为整数

int temp = mac[i]&0xff;

String str = Integer.toHexString(temp);

System.out.println("每8位:"+str);

if(str.length()==1) {

sb.append("0"+str);

}else {

sb.append(str);

}

}

System.out.println("本机MAC地址:"+sb.toString().toUpperCase());

}

}

下面这个方法是获取客户端请求地址

public String getClientIp(HttpServletRequest request) {

String ip = request.getHeader("x-forwarded-for");

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("WL-Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getRemoteAddr();

}

if(ip.trim().contains(",")){

String [] ips=ip.split(",");

ip=ips[0];

}

return ip;

}
