java根据本地IP获取mac地址 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 人气:1想了解java根据本地IP获取mac地址的方法的相关内容吗,java根据本地Ip获取mac地址在本文为您仔细讲解java根据本地IP获取mac地址的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:java,IP,mac,下面大家一起来学习吧。
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; }
