JAVA获取本机IP
public static String getIP() {
String localIP = "";
try {
Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();
while (allNetInterfaces.hasMoreElements()) {
NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
Enumeration<InetAddress> addresses = netInterface.getInetAddresses();
while (addresses.hasMoreElements()) {
InetAddress ip = (InetAddress) addresses.nextElement();
if (ip != null
&& ip instanceof Inet4Address
&& !ip.isLoopbackAddress() //loopback地址即本机地址，IPv4的loopback范围是127.0.0.0 ~ 127.255.255.255
&& ip.getHostAddress().indexOf(":") == -1) {
localIP = ip.getHostAddress();
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return localIP;
