Java获取本地IP方法

获取本地服务器IP经常会出现127.0.0.1,0:0:0:0:0:0:0:1,fe80:0:0:0:960:74bd:e1a0:e5b9%11 这些情况,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());          }      }
