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<mac.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;
 }
