我在使用 Java 获取 Mac 地址时遇到问题。如果机器安装了虚拟机，我会得到不同的 MAC 地址。当我尝试过滤 IP 地址以获取其 mac，同时 ping(检查可达性)我的专用网络 IP 地址(即 172.xx.xx.xx)时，也会发生同样的情况
下面是我正在尝试的一段代码
public static void main(String args[]) throws IOException {
String loca= System.getProperty("user.home")+File.separatorChar+"Documents"+File.separatorChar+"mac.txt";
FileWriter fw = new FileWriter(loca);
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
NetworkInterface interf = interfaces.nextElement();
if (!interf.isLoopback()){ //interf.isUp() && !interf.isLoopback()
Enumeration<InetAddress> mac2 = interf.getInetAddresses();
while(mac2.hasMoreElements()){
String indivIP= mac2.nextElement().getHostAddress();
if(indivIP.contains(".")){
try {
String iptest = "172.x.x.x.x."; //my private network ip
String test2= InetAddress.getLocalHost().getHostName();
System.out.println("HOST NAME = "+test2);
boolean pingStatus = InetAddress.getByName(indivIP).isReachable(3000);
if(pingStatus == true){
System.out.println("IP address = " + indivIP);
byte[] mac = interf.getHardwareAddress();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "" : ""));
}
System.out.println("mac address to use = "+sb.toString().toLowerCase());
String macAddress = sb.toString().toLowerCase();
try {
fw.append("\n");
fw.append("IP : " + indivIP);
fw.append("\n");
fw.append("MacAddress: " + macAddress);
fw.append("\n");
fw.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}else{
//future upgrade
}
}
}
}
fw.flush();
fw.close();
}
我一直在关注的其他主题 Get MAC address on local machine with Java
Get MAC Address of System in Java
我想要的只是获得以太网适配器网络..我的物理MAC地址与硬件无关。

最佳答案
您是否在虚拟机中运行 Java 代码？虚拟机具有虚拟网络适配器，因此您不会在虚拟机内看到物理 MAC(除非您设法将实际设备从主机传递到虚拟机)。
编辑1:
我修改了你的例子。对于您使用的类，我能想到的唯一方法是使用适配器名称。我有一些源自虚拟机的适配器。它们的名称中都有VirtualBox 或Hyper-V。您需要扩展 VIRTUAL_ADAPTER_NAMES 以匹配您的 VMWare 或任何名称。
public class Mac {
private static final int TIMEOUT = 3000;
private static final String[] VIRTUAL_ADAPTER_NAMES = { "VirtualBox", "Hyper-V" };
private static boolean isRelevant(NetworkInterface networkInterface) throws IOException {
if (!networkInterface.isUp()) {
return false;
}
if (networkInterface.isVirtual()) {
return false;
}
if (networkInterface.isLoopback()) {
return false;
}
String name = networkInterface.getDisplayName();
for (String vName : VIRTUAL_ADAPTER_NAMES) {
if (name.contains(vName)) {
return false;
}
}
return true;
}
private static boolean isIpv4Address(String address) {
return address.matches("[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}");
}
private static void printInfoForInterface(NetworkInterface networkInterface) throws IOException {
System.out
.println("Interface: \t" + networkInterface.getDisplayName() + " (" + networkInterface.getName() + ")");
Enumeration<InetAddress> addresses = networkInterface.getInetAddresses();
while (addresses.hasMoreElements()) {
String address = addresses.nextElement().getHostAddress();
if (isIpv4Address(address)) {
if (InetAddress.getByName(address).isReachable(TIMEOUT)) {
System.out.println("IP address: \t" + address);
printMac(networkInterface.getHardwareAddress());
}
}
}
}
private static void printMac(byte[] mac) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "" : ""));
}
System.out.println("MAC: \t\t" + sb.toString().toLowerCase());
}
public static void main(String args[]) throws IOException {
System.out.println("HostName: \t" + InetAddress.getLocalHost().getHostName());
System.out.println("------------------------------------------\n");
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
try {
NetworkInterface networkInterface = interfaces.nextElement();
if (isRelevant(networkInterface)) {
printInfoForInterface(networkInterface);
}
} catch (IOException e) {
System.err.println("An error occured.");
e.printStackTrace(System.err);
}
}
}
}
我得到的输出(有大量虚拟适配器)是
HostName: HOST
------------------------------------------
Interface: Intel(R) Dual Band Wireless-AC 7260 (wlan1)
IP address: 192.168.2.105
MAC: xxxxxxxxxxxx
