通过IP获取地理位置
通过IP获取地理位置
IP数据库选型
1、MaxMind公司（https://www.maxmind.com/en/geoip2-cit） 提供的IP解析数据库有：GeoIP2 City Database（收费）、GeoLite2 City（免费，但2019年1月2日后其不再更新）。
其解析正确率如下：
代码实现:
package com.cz.iptransform
import java.io.File
import java.net.InetAddress
import com.maxmind.geoip2.DatabaseReader
import com.maxmind.geoip2.model.CityResponse
import org.slf4j.LoggerFactory
import scala.collection.mutable
/**
* @Description Convert IP to physical address
* @Author chezhao
* @datae 2019/2/22
*/
object IPAddress1 {
private val logger = LoggerFactory.getLogger(IPAddress1.getClass)
/**
* @Description Convert IP to physical address (通过 GeoIP2 GeoLite2开源免费的数据库 解析)
* @param ip IP that needs to be converted
* @param path The path to the GeoLite2-City.mmdb
* @return map map("key","value") map 的 value 为 中文 和 英文 拼接而成 eg: "江苏#Jiangsu"
*/

2、纯真（ http://www.cz88.net/）IP数据库
纯真IP数据库是开源的IP库，支持多语言。数据库大小：9M，收集了包括中国电信、中国移动、中国联通、长城宽带、聚友宽带等 ISP 的 IP 地址数据，包括网吧数据。IP数据库每5天更新一次。纯真IP库的获取率是99%
代码实现：
package com.cz.iptransform
import com.cz.iputil.IPLocationUtil
import org.slf4j.LoggerFactory
import scala.collection.mutable
/**
* @Description Convert IP to physical address
* @Author chezhao
* @datae 2019/2/22
*/
object IPAddress2 {
private val logger = LoggerFactory.getLogger(IPAddress2.getClass)
/**
* @Description Convert IP to physical address (通过 纯真IP数据库 解析)
* @param ip IP that needs to be converted
* @param path The path to the qqwry.dat
* @return map("key","value")
*/
