javamac地址获取mac地址

发布时间: 2021-03-18 10:56:54

Ⅰ java怎么获取系统mac地址

首先，创建工程，包，和一个类。
在此不加详述，我们直接看代码。
这里，我把这个类命名为GetMacAddr
这里，最最关键的就是这里这个方法。
我们通过NetworkInterface这个类来操作。
也就是通过getLocalHost()方法先得到本机IP，
然后调用getHardwareAddress()方法得到一个byte数组的地址。
我们把六位地址传到一个byte数组里面，然后输出来就是。
不多废话，看代码：
private void getMACAddr()
throws SocketException, UnknownHostException {
// 获得IP
NetworkInterface netInterface =
NetworkInterface.getByInetAddress(InetAddress.getLocalHost());
// 获得Mac地址的byte数组
byte[] macAddr = netInterface.getHardwareAddress();
System.out.print("MAC Addr:\t");
// 循环输出
for (byte b : macAddr) {
// 这里的toHexString()是自己写的格式化输出的方法，见下步。
System.out.print(toHexString(b) + " ");
}
}
上一步骤中，为什么会出现一个toHexString()方法呢？
因为可能10进制转16进制时候可能会出现单字符，
所以，如果有出现单字符的情况，我们在其前面添加一个“0”做占位符。
这也是为了视觉的直观，也夹带着个人的习惯。
private static String toHexString(int integer) {
// 将得来的int类型数字转化为十六进制数
String str = Integer.toHexString((int) (integer & 0xff));
// 如果遇到单字符，前置0占位补满两格
if (str.length() == 1) {
str = "0" + str;
}
return str;
}

Ⅱ JAVA中如何获取指定IP的MAC地址

public static String getMacAddressIP(String remotePcIP) {
String str = "";
String macAddress = "";
try {
Process pp = Runtime.getRuntime().exec("nbtstat -A " + remotePcIP);
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) {
macAddress = str.substring(
str.indexOf("MAC Address") + 14, str.length());
break;
}
}
}
} catch (IOException ex) {
}
return macAddress;
}

Ⅲ 请问java如何获取手机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。

Ⅳ 如何用java获取mac地址

Ⅳ Java代码如何获取客户端的MAC地址

public String getMAC() { String mac = null; try { Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all"); InputStream is = pro.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String message = br.readLine(); int index = -1; while (message != null) { if ((index = message.indexOf("Physical Address")) > 0) { mac = message.substring(index + 36).trim(); break; } message = br.readLine(); } System.out.println(mac); br.close(); pro.destroy(); } catch (IOException e) { System.out.println("Can't get mac address!"); return null; } return mac; }

Ⅵ 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。

Ⅷ java中怎么获取电脑的mac地址

importjava.net.InetAddress;

importjava.net.NetworkInterface;

importjava.net.SocketException;

importjava.net.UnknownHostException;


/*

*物理地址是48位，别和ipv6搞错了

*/

publicclassLOCALMAC{


	/**

	*@paramargs

	*@throwsUnknownHostException

	*@throwsSocketException

	*/

	publicstaticvoidmain(String[]args)throwsUnknownHostException,SocketException{

		//TODOAuto-generatedmethodstub

		

		//得到IP，输出PC-201309011313/122.206.73.83

		InetAddressia=InetAddress.getLocalHost();

		System.out.println(ia);

		getLocalMac(ia);

	}


	privatestaticvoidgetLocalMac(InetAddressia)throwsSocketException{

		//TODOAuto-generatedmethodstub

		//获取网卡，获取地址

		byte[]mac=NetworkInterface.getByInetAddress(ia).getHardwareAddress();

		System.out.println("mac数组长度："+mac.length);

		StringBuffersb=newStringBuffer("");

		for(inti=0;i<mac.length;i++){

			if(i!=0){

				sb.append("-");

			}

			//字节转换为整数

			inttemp=mac[i]&0xff;

			Stringstr=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());

	}

}

Ⅸ Java获取电脑mac地址，如果是双网卡获取的mac地址是不是随机的

是采用类似下面的方法获取mac地址的吗？
NetworkInterface.getByInetAddress(InetAddress.getLocalHost()).getHardwareAddress()
是的话，不是随机的。
是当前使用的，是第一个。
可以写个测试的demo验证下！
