Java web 怎么得到客户端的Mac地址

Java web 怎么得到客户端的Mac地址,第1张

代码如下:

import javanetInetAddress;

import javanetNetworkInterface;

import javanetSocketException;

import javanetUnknownHostException;

/

物理地址是48位,别和ipv6搞错了

/

public class LOCALMAC {

/

@param args

@throws UnknownHostException

@throws SocketException

/

public static void main(String[] args) throws UnknownHostException, SocketException {

// TODO Auto-generated method stub

//得到IP,输出PC-201309011313/1222067383

InetAddress ia = InetAddressgetLocalHost();

Systemoutprintln(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 = NetworkInterfacegetByInetAddress(ia)getHardwareAddress();

Systemoutprintln("mac数组长度:"+maclength);

StringBuffer sb = new StringBuffer("");

for(int i=0; i<maclength; i++) {

if(i!=0) {

sbappend("-");

}

//字节转换为整数

int temp = mac[i]&0xff;

String str = IntegertoHexString(temp);

Systemoutprintln("每8位:"+str);

if(strlength()==1) {

sbappend("0"+str);

}else {

sbappend(str);

}

}

Systemoutprintln("本机MAC地址:"+sbtoString()toUpperCase());

}

}

1得到局域网网段,可由自己机器的IP来确定 (也可以手动获取主机IP-CMD-ipconfig /all)

2根据IP类型,一次遍历局域网内IP地址

JAVA类,编译之后直接运行便可以得到局域网内所有IP,具体怎样使用你自己编写相应代码调用便可

代码如下::

package bean;

import javaio;

import javautil;

public class Ip{

static public HashMap ping; //ping 后的结果集

public HashMap getPing(){ //用来得到ping后的结果集

return ping;

}

//当前线程的数量, 防止过多线程摧毁电脑

static int threadCount = 0;

public Ip() {

ping = new HashMap();

}

public void Ping(String ip) throws Exception{

//最多30个线程

while(threadCount>30)

Threadsleep(50);

threadCount +=1;

PingIp p = new PingIp(ip);

pstart();

}

public void PingAll() throws Exception{

//首先得到本机的IP,得到网段

InetAddress host = InetAddressgetLocalHost();

String hostAddress = hostgetHostAddress();

int k=0;

k=hostAddresslastIndexOf(“”);

String ss = hostAddresssubstring(0,k+1);

for(int i=1;i <=255;i++){ //对所有局域网Ip

String iip=ss+i;

Ping(iip);

}

//等着所有Ping结束

while(threadCount>0)

Threadsleep(50);

}

public static void main(String[] args) throws Exception{

Ip ip= new Ip();

ipPingAll();

javautilSet entries = pingentrySet();

Iterator iter=entriesiterator();

String k;

while(iterhasNext()){

MapEntry entry=(MapEntry)iternext();

String key=(String)entrygetKey();

String value=(String)entrygetValue();

if(valueequals(“true”))

Systemoutprintln(key+“-->”+value);

}

}

class PingIp extends Thread{

public String ip; // IP

public PingIp(String ip){

thisip=ip;

}

public void run(){

try{

Process p= RuntimegetRuntime()。exec (“ping ”+ip+ “ -w 300 -n 1”);

InputStreamReader ir = new InputStreamReader(pgetInputStream());

LineNumberReader input = new LineNumberReader (ir);

//读取结果行

for (int i=1 ; i <7; i++)

inputreadLine();

String line= inputreadLine();

if (linelength() <17 || linesubstring(8,17)。equals(“timed out”))

pingput(ip,“false”);

else

pingput(ip,“true”);

//线程结束

threadCount -= 1;

}catch (IOException e){}

}

}

}
