            }
            reader.close();
            return buffer.toString();
        } catch (MalformedURLException e) {
            e.printStackTrace();

            }
        }
        return null;
    }
}

測試：

@Test  
public void getAddressByIp() throws Exception {  
    // 參數ip  
    String ip = "219.136.134.157";  
    // json_result用於接收返回的json數據  
    String json_result = null;  
    try {  
        json_result = AddressUtils.getAddresses("ip=" + ip, "utf-8");  
    } catch (UnsupportedEncodingException e) {  
        e.printStackTrace();  
    }  
    JSONObject json = JSONObject.fromObject(json_result);  
    System.out.println("json數據： " + json);  
    String country = JSONObject.fromObject(json.get("data")).get("country").toString();  
    String region = JSONObject.fromObject(json.get("data")).get("region").toString();  
    String city = JSONObject.fromObject(json.get("data")).get("city").toString();  
    String county = JSONObject.fromObject(json.get("data")).get("county").toString();  
    String isp = JSONObject.fromObject(json.get("data")).get("isp").toString();  
    String area = JSONObject.fromObject(json.get("data")).get("area").toString();  
    System.out.println("國家： " + country);  
    System.out.println("地區： " + area);  
    System.out.println("省份: " + region);  
    System.out.println("城市： " + city);  
    System.out.println("區/縣： " + county);  
    System.out.println("互聯網服務提供商： " + isp);  
      
    String address = country + "/";  
    address += region + "/";  
    address += city + "/";  
    address += county;  
    System.out.println(address);  

結果：

{"code":0,"data":{"country":"中國","country_id":"CN","area":"華南","area_id":"800000","region":"廣東省","region_id":"440000","city":"廣州市","city_id":"440100","county":"越秀區","county_id":"440104","isp":"電信","isp_id":"100017","ip":"219.136.134.157"}}  
國家： 中國  
地區： 華南  
省份: 廣東省  
城市： 廣州市  
區/縣： 越秀區  
互聯網服務提供商： 電信  
中國/廣東省/廣州市/越秀區  

 但用淘寶的API時，真的很慢，少量數據還可以，一旦數據上萬，那就結束不了了，等了好久都運行不完。

沒辦法，開始嘗試其他方法。

 

用【GeoLite2 City】庫（源自：Java 通過Request請求獲取IP地址對應省份、城市）

 pom.xml:

<dependency>
            <groupId>com.maxmind.geoip2</groupId>
            <artifactId>geoip2</artifactId>
            <version>2.8.1</version>
        </dependency>

測試：

public static void main(String[] args) throws IOException{      
      // 創建 GeoLite2 數據庫     
      File database = new File("/Users/admin/GeoLite2-City.mmdb");     
      // 讀取數據庫內容   
      DatabaseReader reader = new DatabaseReader.Builder(database).build();       
      InetAddress ipAddress = InetAddress.getByName("171.108.233.157");     

      // 獲取查詢結果      
      CityResponse response = null;
        try {
            response = reader.city(ipAddress);

      // 獲取國家信息
      Country country = response.getCountry();
      System.out.println(country.getIsoCode());               // 'CN'
      System.out.println(country.getName());                  // 'China'
      System.out.println(country.getNames().get("zh-CN"));    // '中國'

      // 獲取省份
      Subdivision subdivision = response.getMostSpecificSubdivision();
      System.out.println(subdivision.getName());   // 'Guangxi Zhuangzu Zizhiqu'
      System.out.println(subdivision.getIsoCode()); // '45'
      System.out.println(subdivision.getNames().get("zh-CN")); // '廣西壯族自治區'

      // 獲取城市
      City city = response.getCity();
      System.out.println(city.getName()); // 'Nanning'
      Postal postal = response.getPostal();
      System.out.println(postal.getCode()); // 'null'
      System.out.println(city.getNames().get("zh-CN")); // '南寧'
      Location location = response.getLocation();
      System.out.println(location.getLatitude());  // 22.8167
      System.out.println(location.getLongitude()); // 108.3167
        } catch (GeoIp2Exception e) {
            e.printStackTrace();
        }     


}  

這個就很快了，不過只能獲取到城市。
