Play Geolocation Plugin

Build Status

This is a play module for IP based Geolocation. Currently, the module supports the following services to retrieve the IP data:

Freegeoip

freegeoip.net provides a public HTTP API for software developers to search the geolocation of IP addresses. It uses a database of IP addresses that are associated to cities along with other relevant information like time zone, latitude and longitude.

Maxmind GeoIP2 Country

Determine an Internet visitor's country based on their IP address.

However, support to other geolocation services is possible using the API provided by this plugin.

Compatibility Matrix

Playframework version Module version
2.5.x 2.1.0
2.4.x 2.0.0
2.3.x 1.4.1
2.3.x 1.4.0
2.3.x 1.3.0
2.3.x 1.2.0

How to use

The first step is include the the dependency in your build.sbt or project/Build.scala file:

build.sbt

name := "sitemapper-java-sample"

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  // Add your project dependencies here,
  javaCore,
  javaJdbc,
  "com.edulify" %% "geolocation" % "2.1.0"
)

resolvers ++= Seq(
  Resolver.url("Edulify Repository", url("https://edulify.github.io/modules/releases/"))(Resolver.ivyStylePatterns)
)

project/Build.scala

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {

  val appName         = "geolocation-java-sample"
  val appVersion      = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    "com.edulify" %% "geolocation" % "2.1.0"
  )

  val main = play.Project(appName, appVersion, appDependencies).settings(
    // Add your own project settings here
    resolvers += Resolver.url("Edulify Repository", url("https://edulify.github.io/modules/releases/"))(Resolver.ivyStylePatterns)
  )

}

Enable the module in your conf/application.conf:

Since there is support to Freegeoip and Maxmind, there is also two modules that you enable, depending on which one you want to use. To eanble the module, just add the following line to you conf/application.conf file:

play.modules.enabled += "com.edulify.modules.geolocation.providers.FreegeoipModule"

Or, in case you want to use Maxmind instead:

play.modules.enabled += "com.edulify.modules.geolocation.providers.MaxmindModule"

Configurations

This plugins offers the following configurations:

Configuration Description Default
geolocation.cache.on Caches geolocation results calls false
geolocation.cache.ttl How long it should cache the results 5 seconds
geolocation.enabled If the plugin is enabled or not true
geolocation.maxmind.license Maxmind license none

Per instance, you can add the following in your conf/application.conf:

geolocation {
  cache {
    on = true
    ttl = 10s
  }
  maxmind.license = "your-maxmind-license"
}

Also, notice that the cache uses the cache support offered by Playframework. A complete configuration can be found below:

play.modules.enabled += "com.edulify.modules.geolocation.providers.FreegeoipModule"

geolocation {
  cache {
    on = true
    ttl = 10s
  }
}

Code example

This is the expected way to use the plugin.

import javax.inject.Inject;

import play.mvc.Result;
import play.mvc.Controller;
import play.libs.concurrent.HttpExecution;

import java.util.concurrent.CompletionStage;

import com.edulify.modules.geolocation.Geolocation;
import com.edulify.modules.geolocation.GeolocationService;

public class Application extends Controller {

  private GeolocationService geolocationService;

  @Inject
  public Application(GeolocationService geolocationService) {
    this.geolocationService = geolocationService;
  }

  public static CompletionStage<Result> index() {
    ...
    geolocationService.getGeolocation(request.remoteAddress())
      .thenApplyAsync(new Function<Geolocation, Result>() {
        ...
      }, HttpExecution.defaultContext());
  }
}

Implement your own geolocation service provider

Out of the box, this plugins supports Freegeoip and Maxmind, but you can add your own geolocation service provider implementation and everything will works as expected. To do that, just create an implementation of com.edulify.modules.geolocation.GeolocationProvider and a Play Module to configure it:

The GeolocationProvider:

package com.acme.geolocation;

import com.edulify.modules.geolocation.Geolocation;
import com.edulify.modules.geolocation.GeolocationProvider;

public class MyGeolocationProvider implements GeolocationProvider {

    private WSClient ws;

    @Inject
    public MyGeolocationProvider(WSClient ws) {
        this.ws = ws;
    }

    @Override
    public CompletionStage<Geolocation> get(String ip) {
        // Do a request to your geolocation service and
        // then return a Promise with a geolocation object
    }
}

The Module:

package com.acme.geolocation;

import com.edulify.modules.geolocation.GeolocationProvider;
import com.google.inject.AbstractModule;

public class MyGeolocationModule extends AbstractModule {

  @Override
  protected void configure() {
    // bind to your own MyGeolocationProvider implementation
    bind(GeolocationProvider.class).to(MyGeolocationProvider.class);
  }
}

After that, you just have to configure the provider:

# Configure your own module here
play.modules.enabled += "com.acme.geolocation.MyGeolocationModule"

geolocation {
  cache {
    on = true
    ttl = 10s
  }
}

Things like cache and timeouts will work seamless.
