java获取本机ip地址方法

Enumeration allNetInterfaces = NetworkInterface.getNetworkInterfaces(); InetAddress ip = null; while (allNetInterfaces.hasMoreElements()) { NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement(); System.out.println(netInterface.getName()); Enumeration addresses = netInterface.getInetAddresses(); while (addresses.hasMoreElements()) { ip = (InetAddress) addresses.nextElement(); if (ip != null && ip instanceof Inet4Address) { System.out.println("本机的IP = " + ip.getHostAddress()); } } }
