本文介绍了如何枚举Java中所有已启用的NIC卡的IP地址?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如果没有解析 ipconfig
的输出,有没有人有100%纯粹的java方式呢?
Short of parsing the output of ipconfig
, does anyone have a 100% pure java way of doing this?
推荐答案
这很简单:
try {
InetAddress localhost = InetAddress.getLocalHost();
LOG.info(" IP Addr: " + localhost.getHostAddress());
// Just in case this host has multiple IP addresses....
InetAddress[] allMyIps = InetAddress.getAllByName(localhost.getCanonicalHostName());
if (allMyIps != null && allMyIps.length > 1) {
LOG.info(" Full list of IP addresses:");
for (int i = 0; i < allMyIps.length; i++) {
LOG.info(" " + allMyIps[i]);
}
}
} catch (UnknownHostException e) {
LOG.info(" (error retrieving server host name)");
}
try {
LOG.info("Full list of Network Interfaces:");
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
LOG.info(" " + intf.getName() + " " + intf.getDisplayName());
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
LOG.info(" " + enumIpAddr.nextElement().toString());
}
}
} catch (SocketException e) {
LOG.info(" (error retrieving network interface list)");
}
