Java 根据IP获取客户端Mac地址
博客分类: Java
JavaIEJSPBeanServlet
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
修改的,不建议以此来作为限制依据~

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

最近做一个安全系统,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

} catch (IOException e) {
e.printStackTrace(System.out);
}
return macAddress;
}
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
。
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;
}
