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;
}
