// 获取ip地址
public static String getIpAddress() {
try {
Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();
InetAddress ip = null;
while (allNetInterfaces.hasMoreElements()) {
NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
if (netInterface.isLoopback() || netInterface.isVirtual() || !netInterface.isUp()) {
continue;
} else {
Enumeration<InetAddress> addresses = netInterface.getInetAddresses();
while (addresses.hasMoreElements()) {
ip = addresses.nextElement();
if (ip != null && ip instanceof Inet4Address) {
return ip.getHostAddress();
}
}
}
}
} catch (Exception e) {
// _logger.error("IP地址获取失败", e);
e.printStackTrace();
}
return "";
}

// 获取mac地址
public static String getMacAddress() {
try {
Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();
byte[] mac = null;
while (allNetInterfaces.hasMoreElements()) {
NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
if (netInterface.isLoopback() || netInterface.isVirtual() || !netInterface.isUp()) {
continue;
} else {
mac = netInterface.getHardwareAddress();
if (mac != null) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
if (sb.length() > 0) {
return sb.toString();
}
}
}
}
} catch (Exception e) {
// _logger.error("MAC地址获取失败", e);
e.printStackTrace();
}
return "";
}

此方法过滤了虚拟网卡
