spark streaming 使用geoIP解析IP

1、首先将GEOIP放到服务器上，如，/opt/db/geo/GeoLite2-City.mmdb

2、新建scala sbt工程，测试是否可以顺利解析

import java.io.File
import java.net.InetAddress
import com.maxmind.db.CHMCache
import com.maxmind.geoip2.DatabaseReader
import org.json4s.DefaultFormats

/**
 * Created by zxh on 2016/7/17.
 */
object test {
  implicit val formats = DefaultFormats

  def main(args: Array[String]): Unit = {
    val url = "F:\\Code\\OpenSource\\Data\\spark-sbt\\src\\main\\resources\\GeoLite2-City.mmdb"
    //    val url2 = "/opt/db/geo/GeoLite2-City.mmdb"
    val geoDB = new File(url);
    geoDB.exists()
    val geoIPResolver = new DatabaseReader.Builder(geoDB).withCache(new CHMCache()).build();
    val ip = "222.173.17.203"
    val inetAddress = InetAddress.getByName(ip)
    val geoResponse = geoIPResolver.city(inetAddress)
    val (country, province, city) = (geoResponse.getCountry.getNames.get("zh-CN"), geoResponse.getSubdivisions.get(0).getNames().get("zh-CN"), geoResponse.getCity.getNames.get("zh-CN"))

    println(s"country:$country,province:$province,city:$city")
  }
}

build.sbt 内容如下

import AssemblyKeys._

assemblySettings

mergeStrategy in assembly <<= (mergeStrategy in assembly) { mergeStrategy =>

{

  case entry => {

    val strategy = mergeStrategy(entry)

    if (strategy == MergeStrategy.deduplicate) MergeStrategy.first

    else strategy

  }

}

}

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)

name := "scala_sbt"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies += "com.maxmind.geoip2" % "geoip2" % "2.5.0"

　　将该程序打包，放到服务器上，执行scala -cp ./scala_sbt-assembly-1.0.jar test，解析结果如下

country:中国,province:山东省,city:济南

3、编写streaming程序

import java.io.File
import java.net.InetAddress

import com.maxmind.db.CHMCache
import com.maxmind.geoip2.DatabaseReader
import com.maxmind.geoip2.model.CityResponse
import org.apache.spark.rdd.RDD
import org.apache.spark.streaming.{Time, Seconds, StreamingContext}
import org.apache.spark.{SparkContext, SparkConf}

/**
 * Created by zxh on 2016/7/17.
 */
object geoip {

  def main(args: Array[String]): Unit = {
    val conf = new SparkConf().setAppName("geoip_test").setMaster("local[2]")
    val sc = new SparkContext(conf)
    val ssc = new StreamingContext(sc, Seconds(10))
    val lines = ssc.socketTextStream("localhost", 9999)

    lines.foreachRDD((rdd: RDD[String], t: Time) => {
      rdd.foreachPartition(p => {
        val url2 = "/opt/db/geo/GeoLite2-City.mmdb"
        val geoDB = new File(url2);
        val geoIPResolver = new DatabaseReader.Builder(geoDB).withCache(new CHMCache()).build();

        def resolve_ip(resp: CityResponse): (String, String, String) = {
          (resp.getCountry.getNames.get("zh-CN"), resp.getSubdivisions.get(0).getNames().get("zh-CN"), resp.getCity.getNames.get("zh-CN"))
        }

        p.foreach(x => {
          if (x != None && x != null && x != "") {
            val inetAddress = InetAddress.getByName(x)
            val geoResponse = geoIPResolver.city(inetAddress)
            println(resolve_ip(geoResponse))
          }
        })
      })
    })

    ssc.start
  }
}
build.sbt

libraryDependencies += "com.maxmind.geoip2" % "geoip2" % "2.5.0"

注意：红色部分需要放到foreachPartition内部，原因如下：

1、减少加载文件次数，一个Partition只加载一次

2、resolve_ip 函数参数为CityResponse，此参数不可序列化，所以要在Partition内部，这样就不会在节点之间序列化传输

3、com.maxmind.geoip2 版本需要是 2.5.0，以便和spark本身兼容，否则会报错如下：

val geoIPResolver = new DatabaseReader.Builder(geoDB).withCache(new CHMCache()).build();
java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.node.ArrayNode.<init>(Lcom/fasterxml/jackson/databind/node/JsonNodeFactory;Ljava/util/List;)V
