GeoLite2实现ip地址转化为城市地址-java

GeoLite2实现ip地址转化为城市地址-java

1、GeoLite2下载

下载地址：https://www.maxmind.com/en/accounts/363203/geoip/downloads。下载GeoLite2 City即可。

2、导入依赖

<dependency>
    <groupId>com.maxmind.geoip2groupId>
    <artifactId>geoip2artifactId>
    <version>2.14.0version>
dependency>

3、写测试类

package com.soso.influx.demo;

import com.maxmind.geoip2.DatabaseReader;
import com.maxmind.geoip2.exception.GeoIp2Exception;
import com.maxmind.geoip2.model.CityResponse;
import com.maxmind.geoip2.record.*;

import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.io.RandomAccessFile;
import java.net.InetAddress;

public class IP2Adrress {
    public static void main(String[] args) throws IOException, GeoIp2Exception {
        //GeoIP2-City 数据库文件
//        File database = new File("GeoLite2-City.mmdb");
        //将GeoLite2-City.mmdb放在resources中，然后使用下面的方式进行读取数据
        InputStream database = IP2Adrress.class.getClassLoader().getResourceAsStream("GeoLite2-City.mmdb");

        // 创建 DatabaseReader对象
        DatabaseReader reader = new DatabaseReader.Builder(database).build();

        InetAddress ipAddress = InetAddress.getByName("128.101.101.101");

        CityResponse response = reader.city(ipAddress);

        Country country = response.getCountry();
        System.out.println(country.getIsoCode());            // 'US'
        System.out.println(country.getName());               // 'United States'
        System.out.println(country.getNames().get("zh-CN")); // '美国'

        Subdivision subdivision = response.getMostSpecificSubdivision();
        System.out.println(subdivision.getName());    // 'Minnesota'
        System.out.println(subdivision.getIsoCode()); // 'MN'

        City city = response.getCity();
        System.out.println(city.getName()); // 'Minneapolis'

        Postal postal = response.getPostal();
        System.out.println(postal.getCode()); // '55455'

        Location location = response.getLocation();
        System.out.println(location.getLatitude());  // 44.9733
        System.out.println(location.getLongitude()); // -93.2323
    }
}

该类再继承udf类，再把参数转化一下，就可以用在hive上的清洗了。
