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;
    }
}
