Java implementation obtains geographic location based on IP address _java

Recent project a feature needs to be based on IP address from Third-party interface to obtain a detailed geographical location, from the Internet to find a lot of examples, the main interface with Sina, Taobao, Tencent. Try Taobao, if it is a small order of magnitude can also, if the order of magnitude to reach the 100,000 level on the slow speed, will lead to system crashes. The following example is Sina, the example is not suitable for each project, need to change.

/** ipsearchurl=http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip= (This is Sina's interface address)
In the project Sina's interface address is not directly written dead, but to read the property file. */public static string Getipinfobysina (String IP) {//Read Property file (property file Key-value and format) final String prop_ipsearchurl= IP
    Searchurl ";
    Final String ret_success= "1";
    Final String ret= "RET";
    Final String province= "province";
    Final String city= "City";
    Final String district= "DISTRICT";
    Final String isp= "ISP";
    String ipaddress= "";
    if (Stringutils.isblank (IP)) {return null; String url = systemparampropertyutils.getsystemparamkeyvalue (prop_ipsearchurl);//This is the URL in the subordinate file, that is, the Sina interface address if (Strin Gutils.isnotblank (URL)) {String path=url+ip;//"http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&
      Ip= "+IP;
      HttpClient httpclient = new HttpClient ();
      map<string, string> parammap = new hashmap<string, string> ();
      
      String remoteipinfo= ""; try {remoteipinfo = HttpclientutIl.request (httpclient, Path, Parammap, "Sina");
      catch (Exception e) {e.printstacktrace ();
        } if (Stringutils.isnotblank (Remoteipinfo)) {String _ret=searchvalue (remoteipinfo, ret);
          if (Ret_success.equals (_ret)) {String Provincename=searchvalue (remoteipinfo, province);
          String Cityname=searchvalue (Remoteipinfo, city);
          String District=searchvalue (Remoteipinfo, District);
          String Isp=searchvalue (Remoteipinfo, ISP);
        Ipaddress=provincename+cityname+district+isp;
  }} return ipaddress;
   private static string Searchvalue (String remoteipinfo,string key) {string _value= "";
     if (Stringutils.isnotblank (Remoteipinfo)) {_value=stringutils.substringbetween (remoteipinfo, "\" "+key+" \ ":", ",");        
     if (Stringutils.isnotblank (_value)) {_value=unicodeutils.decodeunicode (_value);
  } return _value;
 }

Read Sina's interface address quickly, I personally tested to 90,000 or so, 10 minutes. Taobao words one hours, more than 50,000. Another trick is to store the IP you read in the map, and then take it out of the map the next time you read it, so much faster. This will spawn a lot of problems, the log file to reach millions, tens, how to solve. such as Taobao, a second number of orders, each order IP is not the same. I don't know how to solve it. A great God knows to return to me.
The following is the use of Taobao.
