[ Java 套件 ] GeoLite2 - GeoIP2 Java API - Database Example

Prerequisite 
在試用下面範例代碼使用 IP 找對應 Geo location 前, 請先下載對應 DB 與 Java GeoLite2 library: 
* GeoLite2 Free Downloadable Databases 
* GeoIP2-java Github (geoip2-2.8.1-with-dependencies.zip)

1. // A File object pointing to your GeoIP2 or GeoLite2 database  
2. File database = new File("/path/to/GeoIP2-City.mmdb");  
3.   
4. // This creates the DatabaseReader object, which should be reused across  
5. // lookups.  
6. DatabaseReader reader = new DatabaseReader.Builder(database).build();  
7.   
8. InetAddress ipAddress = InetAddress.getByName("128.101.101.101");  
9.   
10. // Replace "city" with the appropriate method for your database, e.g.,  
11. // "country".

13.   
14. Country country = response.getCountry();  
15. System.out.println(country.getIsoCode());            // 'US'  
16. System.out.println(country.getName());               // 'United States'
