Java获取本地IP地址

import java.net.InetAddress;

import java.net.UnknownHostException;

public class IpTest {

    public static void main(String args[]) throws UnknownHostException {

       String ip = InetAddress.getLocalHost().getHostAddress();

       System.out.println(ip);

    }

}

功能是实现了，但是写的不好！

抽取！抽取！

public class Test {

    private static final Logger logger = LoggerFactory.getLogger(Test.class);

    public static void main(String[] args) throws ParseException {

        String ipAddress = getNativeIp();

        System.out.println(ipAddress);

    }

    //获得本机IP

    private static String getNativeIp() {

        String ipAddrStr = "";

        try {

            ServerSocket ss = new ServerSocket(0);

            ipAddrStr = ss.getInetAddress().getLocalHost().getHostAddress();

            ss.close();

        } catch (Exception e) {

            logger.error("获取本地ip失败:{}", e.getMessage());

        }

        return ipAddrStr;

    }

}
