java如何获取客户端mac地址？

以下代码实现浏览器中获取mac地址放入一个输入框或隐藏域，随登录信息一起提交到服务器。因为安全级别的关系可能会出现警告，可选择允许执行。长期使用的话建议用户将改站点加入信任站点或把安全级别调低。

java如何获取mac地址？

以windows举例。

运行命令" cmd ipconfig /all"就会出现以下结果

Physical Address. . . . . . . . . : 20-CF-30-9A-60-EE

。

java就能过这样的命令来获取。以下是示例。

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class TestMac

{

public static void main(String[] args) {

System.out.println("Operation System=" + getOsName());

System.out.println("Mac Address=" + getMACAddress());

System.out.println("通过ip获取mac"+getMACAddress("192.168.1.101"));

}

public static String getOsName() {

String os = "";

os = System.getProperty("os.name");

return os;

}

public static String getMACAddress() {

String address = "";

String os = getOsName();

if (os.startsWith("Windows")) {

try {

String command = "cmd.exe /c ipconfig /all";

Process p = Runtime.getRuntime().exec(command);

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line;

while ((line = br.readLine()) != null) {

if (line.indexOf("Physical Address") 0) {

int index = line.indexOf(":");

index += 2;

address = line.substring(index);

break;

}

br.close();

return address.trim();

} catch (IOException e) {

}

} else if (os.startsWith("Linux")) {

String command = "/bin/sh -c ifconfig -a";

Process p;

try {

p = Runtime.getRuntime().exec(command);

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line;

while ((line = br.readLine()) != null) {

if (line.indexOf("HWaddr") 0) {

int index = line.indexOf("HWaddr") + "HWaddr".length();

address = line.substring(index);

break;

}

br.close();

} catch (IOException e) {

}

address = address.trim();

return address;

}

public static 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;

}

剑天梦的回答原理和我这个一样，都是通过Process 执行命令。我直接补充到答案里了。不过

我这边运行那个命令出来的结果很多，那么花的时间就长了。优点是能够获取别人的mac地址。

Java web 怎么得到客户端的Mac地址

代码如下：

import java.net.InetAddress;

import java.net.NetworkInterface;

import java.net.SocketException;

import java.net.UnknownHostException;

* 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-201309011313/122.206.73.83

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; imac.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());

}
