以下代码可解决此问题：

public static void main(String[] args) {
        try {
            Enumeration<networkinterface> enumeration = NetworkInterface
                    .getNetworkInterfaces();
            while (enumeration.hasMoreElements()) {
                NetworkInterface networkInterface = enumeration.nextElement();
                if (networkInterface.isUp()) {
                    Enumeration<inetaddress> addressEnumeration = networkInterface
                            .getInetAddresses();
                    while (addressEnumeration.hasMoreElements()) {
                        String ip = addressEnumeration.nextElement()
                                .getHostAddress();
                        final String REGX_IP = "((25[0-5]|2[0-4]\\d|1\\d{2}|[1-9]\\d|\\d)\\.){3}(25[0-5]|2[0-4]\\d|1\\d{2}|[1-9]\\d|\\d)";
                        if (ip.matches(REGX_IP) && !ip.equals("127.0.0.1")) {
                            System.out.println(ip);
                        }
   
                    }
                }
            }
        } catch (Exception e) {
            log.error("获取本机ip出现异常，异常信息为：" + e.getMessage());
        }
    }</inetaddress></networkinterface>
