概述:本文主要介绍JSF/JAVA根据IP获取客户端Mac地址,希望对大家有帮助。

  需要对用户的 ip 和 mac 地址进行验证,这里用到获取客户端ip和mac地址的两个方法,留存。

  1.获取客户端ip地址( 这个必须从客户端传到后台):

  jsp页面下,很简单,request.getRemoteAddr() ;

  因为系统的VIew层是用JSF来实现的,因此页面上没法直接获得类似request,在bean里做了个强制转换

  Java代码

  public String getMyIP() {

  try {

  FacesContext fc = FacesContext.getCurrentInstance();

  HttpServletRequest request = (HttpServletRequest)fc.getExternalContext().getRequest();

  return request.getRemoteAddr();

  }

  catch (Exception e) {

  e.printStackTrace();

  }

  return "";

  }

  2.获取客户端mac地址

  调用window的命令,在后台Bean里实现 通过ip来获取mac地址。方法如下:

  Java代码

  public String getMACAddress(String ip){

  String str = "";

  String macAddress = "";

  try {

  Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);

  InputStreamReader ir = new InputStreamReader(p.getInputStream());

  LineNumberReader input = new LineNumberReader(ir);

  for (int i = 1; i < 100; i++) {

  str = input.readLine();

  if (str != null) {

  if (str.indexOf("MAC Address") > 1) {

  macAddress = str.substring(str.indexOf("MAC Address") + 14, str.length());

  break;

  }

  }

  }

  } catch (IOException e) {

  e.printStackTrace(System.out);

  }

  return macAddress;

  }

  完整代码:

  Java代码

  import java.io.IOException;

  import java.io.InputStreamReader;

  import java.io.LineNumberReader;

  public class GetMACAddress {

  public String getMACAddress(String ipAddress) {

  String str = "", strMAC = "", macAddress = "";

  try {

  Process pp = Runtime.getRuntime().exec("nbtstat -a " + ipAddress);

  InputStreamReader ir = new InputStreamReader(pp.getInputStream());

  LineNumberReader input = new LineNumberReader(ir);

  for (int i = 1; i < 100; i++) {

  str = input.readLine();

  if (str != null) {

  if (str.indexOf("MAC Address") > 1) {

  strMAC = str.substring(str.indexOf("MAC Address") + 14,

  str.length());

  break;

  }

  }

  }

  } catch (IOException ex) {

  return "Can't Get MAC Address!";

  }

  //

  if (strMAC.length() < 17) {

  return "Error!";

  }

  macAddress = strMAC.substring(0, 2) + ":" + strMAC.substring(3, 5)

  + ":" + strMAC.substring(6, 8) + ":" + strMAC.substring(9, 11)

  + ":" + strMAC.substring(12, 14) + ":"

  + strMAC.substring(15, 17);

  //

  return macAddress;

  }

public static void main(String[] args) {

  GetMACAddress getMACAddress = new GetMACAddress();

  System.out.println(getMACAddress.getMACAddress("59.78.63.38")); //获得该ip地址的mac地址

  }

  public static String procAll(String str) {

  return procStringEnd(procFirstMac(procAddress(str)));

  }

  public static String procAddress(String str) {

  int indexof = str.indexOf("Physical Address");

  if (indexof > 0) {

  return str.substring(indexof, str.length());

  }

  return str;

  }

  public static String procFirstMac(String str) {

  int indexof = str.indexOf(":");

  if (indexof > 0) {

  return str.substring(indexof + 1, str.length()).trim();

  }

  return str;

  }

  public static String procStringEnd(String str) {

  int indexof = str.indexOf("\r");

  if (indexof > 0) {

  return str.substring(0, indexof).trim();

  }

  return str;

  }

  }

  只要写一个servlet来调用这个类的getMACAddress(String netip)方法就可以获得客户端的mac地址了,相信你会写jsp应该对servlet也不陌生吧,在jsp中调用servlet通过session传递返回的mac地址,加以判断就可以了

  mac地址是可以通过注册表修改的,不建议以此来作为限制依据~

  补充:

  关于获取IP地址的方式,最近在linux下有一个教训,如果单纯通过InetAddress来获取IP地址,就会出现在不同的机器上IP地址不同的问题。

  InetAddress.getLocalHost().getAddress() 实际上是根据hostname来获取IP地址的。linux系统在刚刚装完默认的hostname是localhost,所以通过上面代码获取到的本机 ip就是127.0.0.1, 相对应,比如我的hostname就是rjlin.atsig.com 返回的ip地址确是atsig.com的地址。暂时采用下面代码来处理,当然还不够灵活:

  public static byte[] getIp() throws UnknownHostException {

  byte[] b = InetAddress.getLocalHost().getAddress();

  Enumeration allNetInterfaces = null;

  try {

  allNetInterfaces = NetworkInterface.getNetworkInterfaces();

  } catch (SocketException e) {

  e.printStackTrace();

  }

  InetAddress ip = null;

  NetworkInterface netInterface = null;

  while (allNetInterfaces.hasMoreElements()) {

  netInterface = (NetworkInterface) allNetInterfaces.nextElement();

  if (netInterface.getName().trim().equals("eth0")){

  Enumeration addresses = netInterface.getInetAddresses();

  while (addresses.hasMoreElements()) {

  ip = (InetAddress) addresses.nextElement();

  }

  break;

  }

  }

  if (ip != null && ip instanceof Inet4Address) {

  return b = ip.getAddress();

  }

  return b;

  }

  补充:

  // 获取真实IP的方法().

  public String getIpAddr(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();

  }

  return ip;

  }
