java获取本机IPV4地址，非127.0.0.1

1private static String getHostIp(){
2        try{
3            Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();
4            while (allNetInterfaces.hasMoreElements()){

10                            && ip instanceof Inet4Address
11                            && !ip.isLoopbackAddress() //loopback地址即本机地址，IPv4的loopback范围是127.0.0.0 ~ 127.255.255.255
12                            && ip.getHostAddress().indexOf(":")==-1){
13                        System.out.println("本机的IP = " + ip.getHostAddress());
