IP 轉換爲實際地址 《二》

項目中，有這麼一個需求，要把用戶操作操作信息做成日誌。現在要獲取用戶的登錄IP地址。並轉爲實際地址。現在給出源碼。
第一步獲取用戶登錄IP

// 獲取外網真實 IP 地址
        public static String getV4IP(HttpServletRequest request){
            String ip = "";
            String chinaz = "http://ip.chinaz.com";

            StringBuilder inputLine = new StringBuilder();
            String read = "";
            URL url = null;
            HttpURLConnection urlConnection = null;
            BufferedReader in = null;
            try {
                url = new URL(chinaz);
                urlConnection = (HttpURLConnection) url.openConnection();
                in = new BufferedReader( new InputStreamReader(urlConnection.getInputStream(),"UTF-8"));
                while((read=in.readLine())!=null){
                    inputLine.append(read+"\r\n");
                }
                //System.out.println(inputLine.toString());
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }finally{
                if(in!=null){
                    try {
                        in.close();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }

            Pattern p = Pattern.compile("\\<dd class\\=\"fz24\">(.*?)\\<\\/dd>");
            Matcher m = p.matcher(inputLine.toString());
            if(m.find()){
                String ipstr = m.group(1);
                ip = ipstr;
                //System.out.println(ipstr);
            }
            return ip;
        }

第二步把獲取IP 轉爲地址
給出源碼：IpLocationResult

package com.whf.util;

/**
 * 由ip地址對應的信息的對象模型
 * */
public class IpLocationResult {
    private Integer ret;
    private Integer start;
    private Integer end;
    /**
     * 國家
     * */
    private String country;
    /**
     * 省份
     * */
    private String province;
    /**
     * 城市
     * */
    private String city;
    private String district;
    /**
     * 網絡提供商
     * */
    private String isp;
    private String type;
    private String desc;
    public Integer getRet() {
        return ret;
    }
    public void setRet(Integer ret) {
        this.ret = ret;
    }
    public Integer getStart() {
        return start;
    }
    public void setStart(Integer start) {
        this.start = start;
    }
    public Integer getEnd() {
        return end;
    }
    public void setEnd(Integer end) {
        this.end = end;
    }
    public String getCountry() {
        return country;
    }
    public void setCountry(String country) {
        this.country = country;
    }
    public String getProvince() {
        return province;
    }
    public void setProvince(String province) {
        this.province = province;
    }
    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public String getDistrict() {
        return district;
    }
    public void setDistrict(String district) {
        this.district = district;
    }
    public String getIsp() {
        return isp;
    }
    public void setIsp(String isp) {
        this.isp = isp;
    }
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
    public String getDesc() {
        return desc;
    }
    public void setDesc(String desc) {
        this.desc = desc;
    }

}

IpLocationService

package com.whf.util;


import com.google.gson.Gson;


/**
* 處理用戶位置信息的業務邏輯類
* @author HUPENG
* @version 1.0.0
* @since jdk1.7
* */
public  class IpLocationService {

    private IpLocationResult ipLocationResult;

    /**
     * 以ip地址獲取地理位置信息等，返回一個對象模型
     * @param ipAddress ip地址，形式諸如   123.123.123.123
     * */
    public IpLocationResult getIpLocationResult(String ipAddress){
        if (ipLocationResult!=null) {
            return ipLocationResult;
        }
        String url = "http://int.dpool.sina.com.cn/iplookup/iplookup.php";
        String param = "format=json&ip=" + ipAddress;
        String httpResponse = null;
        try {
            httpResponse = HttpRequest.sendGet(url, param);
        } catch (Exception e) {
            // TODO: handle exception
            System.err.println("發送GET請求時發生錯誤");
            e.printStackTrace();
        }


        try {
            ipLocationResult= new Gson().fromJson(httpResponse, IpLocationResult.class);
            return ipLocationResult;
        } catch (Exception e) {
            // TODO: handle exception
            //System.err.println("解析json字符串時發生錯誤，請不要使用例如127.0.0.1的訪問使用了本接口的網站");
            //e.printStackTrace();
            ipLocationResult = new IpLocationResult();
//          ipLocationResult.setCity("本地");
//          ipLocationResult.setCountry("本地");
            ipLocationResult.setCountry("本地");
            ipLocationResult.setProvince("");
            ipLocationResult.setCity("");;
            return ipLocationResult;
        }
    }
}
