Linux下用Java获取本机IP

可能有多个网卡包括虚拟网卡,需要进行排除

String ip = "";
try {
    Enumeration<?> e1 = NetworkInterface.getNetworkInterfaces();//获取多个网卡
    while (e1.hasMoreElements()) {
    NetworkInterface ni = (NetworkInterface) e1.nextElement();

    if(("eth0").equals(ni.getName()) || ("ens33").equals(ni.getName())){//取“eth0”和“ens33”两个网卡
        Enumeration<?> e2 = ni.getInetAddresses();
        while (e2.hasMoreElements()) {
          InetAddress ia = (InetAddress) e2.nextElement();
          if (ia instanceof Inet6Address) {//排除IPv6地址
              continue;
          }
          ip = ia.getHostAddress();
          }
          break;
      }
    }
} catch (SocketException e) {
    e.printStackTrace();
}
