Java-No.01 Java Linux下擷取伺服器ip地址

標籤：

1、在window下擷取本機ip地址

InetAddress inet = InetAddress.getLocalHost();  System.out.println("原生ip=" + inet.getHostAddress());

該方法在linux下擷取到的ip為127.0.0.1，原因是你linux伺服器上hosts配置了 127.0.0.1 localhost

可以修改hosts下將127.0.0.1改成你的本機真實ip地址

2、linux下代碼擷取本機ip地址

public static String getLocalHostIP() {        try {            for (Enumeration<NetworkInterface> nis = NetworkInterface                    .getNetworkInterfaces(); nis.hasMoreElements();) {                NetworkInterface ni = nis.nextElement();                if (ni.isLoopback() || !ni.isUp())                    continue;                for (Enumeration<InetAddress> ias = ni.getInetAddresses(); ias.hasMoreElements();) {                    InetAddress ia = ias.nextElement();                    if (ia instanceof Inet6Address) continue;                    return ia.getHostAddress();                }            }        } catch (Exception e) {            e.printStackTrace();        }        return "";    }
