使用java查找ip地址的省市区，使用淘宝的ip地址库http://ip.taobao.com/index.php

package com.common.util;
    
    import java.net.InetAddress;
    import java.net.NetworkInterface;
    import java.util.Enumeration;
    import java.util.Map;
    import java.util.regex.Pattern;
    
    import com.alibaba.fastjson.JSON;
    import com.alibaba.fastjson.JSONObject;
    import com.google.common.collect.Maps;
    
    /**
     * IP地址实用类
     */
    public class IpAddressUtil {
      
      private static final String LOCALHOST = "127.0.0.1";
      private static final String ANYHOST = "0.0.0.0";
      private static final Pattern IP_PATTERN = Pattern.compile("\\d{1,3}(\\.\\d{1,3}){3,5}$");
      
      public static void main(String[] args) {
        System.out.println(getIpRegion("***.***.***.**"));
      }
      
      /**
       * 获取指定IP的区域位置
       */
      public static String getIpRegion(String ip){
        String urlStr = "http://ip.taobao.com/service/getIpInfo.php";
        Map<String, Object> params = Maps.newHashMap();
        params.put("ip", ip);
        String returnStr = HttpUtil.doPost(urlStr, params);
        if (returnStr != null) {
          String[] temp = returnStr.split(",");
          if (temp.length < 3) {
            return "本地";
          }
          JSONObject jsonObject = JSON.parseObject(returnStr).getJSONObject("data");
          String region = jsonObject.getString("region");
          String city = jsonObject.getString("city");
          String isp = jsonObject.getString("isp");
          return region + city + "[" + isp+"]";
        }
        return null;
      }
      
    
        /**

         * @return 本地网卡IP
         */
      public static String getLocalAddress() {
            String localIp = LOCALHOST;
            try {
                Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
                if (interfaces != null) {
                    while (interfaces.hasMoreElements()) {
                        try {
                            NetworkInterface network = interfaces.nextElement();
                            Enumeration<InetAddress> addresses = network.getInetAddresses();
                            while (addresses.hasMoreElements()) {

                                    if (isValidAddress(address)) {
                                        return address.getHostAddress();
                                    }
                                } catch (Throwable e) {
                                    e.printStackTrace();
                                }
                            }
                        } catch (Throwable e) {
                            e.printStackTrace();
                        }
                    }
                }
            } catch (Throwable e) {
                e.printStackTrace();
            }
            return localIp;
        }
        
        private static boolean isValidAddress(InetAddress address) {
            if (address == null || address.isLoopbackAddress())
                return false;
            String name = address.getHostAddress();
            return (name != null && !ANYHOST.equals(name) && !LOCALHOST.equals(name) && IP_PATTERN.matcher(name).matches());
        }
    }

查询结果：
