IP 转换为实际地址 《二》

项目中，有这么一个需求，要把用户操作操作信息做成日志。现在要获取用户的登录IP地址。并转为实际地址。现在给出源码。
第一步获取用户登录IP

// 获取外网真实 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;        }

第二步把获取IP 转为地址
给出源码：IpLocationResult

package com.whf.util;/** * 由ip地址对应的信息的对象模型 * */public class IpLocationResult {    private Integer ret;    private Integer start;    private Integer end;    /**     * 国家     * */    private String country;    /**     * 省份     * */    private String province;    /**     * 城市     * */    private String city;    private String district;    /**     * 网络提供商     * */    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;/*** 处理用户位置信息的业务逻辑类* @author HUPENG* @version 1.0.0* @since jdk1.7* */public  class IpLocationService {    private IpLocationResult ipLocationResult;    /**     * 以ip地址获取地理位置信息等，返回一个对象模型     * @param ipAddress ip地址，形式诸如   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("发送GET请求时发生错误");            e.printStackTrace();        }        try {            ipLocationResult= new Gson().fromJson(httpResponse, IpLocationResult.class);            return ipLocationResult;        } catch (Exception e) {            // TODO: handle exception            //System.err.println("解析json字符串时发生错误，请不要使用例如127.0.0.1的访问使用了本接口的网站");            //e.printStackTrace();            ipLocationResult = new IpLocationResult();//          ipLocationResult.setCity("本地");//          ipLocationResult.setCountry("本地");            ipLocationResult.setCountry("本地");            ipLocationResult.setProvince("");            ipLocationResult.setCity("");;            return ipLocationResult;        }    }}

HttpRequest

package com.whf.util;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.URL;import java.net.URLConnection;import java.util.List;import java.util.Map;/** * 发送http请求的类 * */public class HttpRequest {    /**     * 向指定URL发送GET方法的请求     *      * @param url     *            发送请求的URL     * @param param     *            请求参数，请求参数应该是 name1=value1&name2=value2 的形式。     * @return URL 所代表远程资源的响应结果     */    public static String sendGet(String url, String param) {        String result = "";        BufferedReader in = null;        try {            String urlNameString = url + "?" + param;            URL realUrl = new URL(urlNameString);            // 打开和URL之间的连接            URLConnection connection = realUrl.openConnection();            // 设置通用的请求属性            connection.setRequestProperty("accept", "*/*");            connection.setRequestProperty("connection", "Keep-Alive");            connection.setRequestProperty("user-agent",                    "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");            // 建立实际的连接            connection.connect();            // 获取所有响应头字段            Map<String, List<String>> map = connection.getHeaderFields();            // 遍历所有的响应头字段            for (String key : map.keySet()) {                //System.out.println(key + "--->" + map.get(key));            }            // 定义 BufferedReader输入流来读取URL的响应            in = new BufferedReader(new InputStreamReader(                    connection.getInputStream()));            String line;            while ((line = in.readLine()) != null) {                result += line;            }        } catch (Exception e) {            System.out.println("发送GET请求出现异常！" + e);            e.printStackTrace();        }        // 使用finally块来关闭输入流        finally {            try {                if (in != null) {                    in.close();                }            } catch (Exception e2) {                e2.printStackTrace();            }        }        return result;    }    /**     * 向指定 URL 发送POST方法的请求     *      * @param url     *            发送请求的 URL     * @param param     *            请求参数，请求参数应该是 name1=value1&name2=value2 的形式。     * @return 所代表远程资源的响应结果     */    public static String sendPost(String url, String param) {        PrintWriter out = null;        BufferedReader in = null;        String result = "";        try {            URL realUrl = new URL(url);            // 打开和URL之间的连接            URLConnection conn = realUrl.openConnection();            // 设置通用的请求属性            conn.setRequestProperty("accept", "*/*");            conn.setRequestProperty("connection", "Keep-Alive");            conn.setRequestProperty("user-agent",                    "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");            // 发送POST请求必须设置如下两行            conn.setDoOutput(true);            conn.setDoInput(true);            // 获取URLConnection对象对应的输出流            out = new PrintWriter(conn.getOutputStream());            // 发送请求参数            out.print(param);            // flush输出流的缓冲            out.flush();            // 定义BufferedReader输入流来读取URL的响应            in = new BufferedReader(                    new InputStreamReader(conn.getInputStream()));            String line;            while ((line = in.readLine()) != null) {                result += line;            }        } catch (Exception e) {            System.out.println("发送 POST 请求出现异常！"+e);            e.printStackTrace();        }        //使用finally块来关闭输出流、输入流        finally{            try{                if(out!=null){                    out.close();                }                if(in!=null){                    in.close();                }            }            catch(IOException ex){                ex.printStackTrace();            }        }        return result;    }}
