java中通過網卡名稱擷取IP地址

複製代碼 代碼如下:package me.xuzs.sso.test;

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

public class InternetTest {

public static void main(String[] args) {
String netCard = "lo";
try {
Enumeration<NetworkInterface> netInterfaces = NetworkInterface
.getNetworkInterfaces();
if (netInterfaces.hasMoreElements()) {
NetworkInterface netInterface = netInterfaces.nextElement();
if (netCard.equals(netInterface.getName())) {
// 子介面，linux下會取到父介面？？
Enumeration<NetworkInterface> subnetInterfaces = netInterface
.getSubInterfaces();
while (subnetInterfaces.hasMoreElements()) {
NetworkInterface subnetInterface = subnetInterfaces
.nextElement();
System.out.println(subnetInterface.getName());
Enumeration<InetAddress> subaddresses = netInterface
.getInetAddresses();
while (subaddresses.hasMoreElements()) {
InetAddress subaddress = subaddresses.nextElement();
System.out.println(subaddress.getHostAddress());
}
}
// 列印介面下所有IP
System.out.println(netInterface.getName());
Enumeration<InetAddress> addresses = netInterface
.getInetAddresses();
while (addresses.hasMoreElements()) {
InetAddress address = addresses.nextElement();
System.out.println(address.getHostAddress());
}
}
}
} catch (SocketException e) {
e.printStackTrace();
}
}
}
