java實現根據ip地址獲取地理位置

最近項目某個功能需要根據ip地址從第三方接口獲取詳細的地理位置，從網上找了很多例子，主要接口有新浪的，淘寶的，騰訊的。試了淘寶的，如果是數量級小的還可以，如果數量級達到上十萬級就速度慢了，會導致系統崩潰。下面例子是新浪的，例子不是適合每個項目，需要改一下.

 /** ipSearchUrl=http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=（這是新浪的接口地址） 在項目中新浪的接口地址沒有直接寫死，而是去讀屬性文件。 */ public static String getIpInfoBySina(String ip){ // 讀取屬性文件(屬性文件key-value和格式) final String PROP_IPSEARCHURL="ipSearchUrl"; 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);//這個是從屬性文件中獲取url，即新浪接口地址if(StringUtils.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; }

讀新浪的接口地址很快，我本人測試到了九萬條左右，十分鐘。淘寶的話一個多小時，五萬多條。還有一個小技巧，就是把讀到的ip存到map中，然後下次讀的話就直接從map取出，這樣快很多。這個會衍生出很多問題，當日誌文件達到百萬級，千萬級，怎麼解決。類似淘寶這樣的，一秒多少訂單，每個訂單ip不一樣。我不知道怎麼解決。有大神知道回我一下。
下面是用淘寶的。
