Best way to get geo-location in Java [closed]

by

An easy way is with GeoLite (http://dev.maxmind.com/geoip/legacy/geolite/). Because it uses a local database no web service calls are needed and it’s much faster for geocoding large numbers of IPs.

Here is how:

Add this Maven artifact:

<dependency>
    <groupId>com.maxmind.geoip</groupId>
    <artifactId>geoip-api</artifactId>
    <version>1.2.11</version>
</dependency>

Download the geolocation data file from http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz

Unpack the file into any folder. Then do:

LookupService cl = new LookupService("/var/geolite/GeoLiteCity.dat",
                    LookupService.GEOIP_MEMORY_CACHE | LookupService.GEOIP_CHECK_CACHE);

Location location = cl.getLocation("some ip address");

The result will be in the Location object in the latitude, longitude, city, region and countryCode properties.

Please take a look at their accuracy estimates to ensure it meets the needs of your project: http://www.maxmind.com/en/geolite_city_accuracy .
