Akka Persistence MongoDB Weather example

In this section, we will develop a simple Akka Persistence Weather Application to explore the CQRS/ES pattern. We will use MongoDB as our application Akka Persistence journal to store our events.

Use the following steps to experiment with Akka Persistence with MongoDB:

1. Create an SBT Scala project from your favorite IDE:

      Project name: akka-persistence-mongodb-weather-ap 

2. Update build.sbt with the following content:

build.sbt:

      name := "akka-persistence-mongodb-weather-app"
      version := "1.0.0"
      scalaVersion := "2.12.4"
      libraryDependencies ++= {
        Seq(
          "com.typesafe.akka" %% "akka-actor" % "2.5.9",
          "com.typesafe.akka" %% "akka-persistence" % "2.5.9",
          "com.typesafe.akka" %% "akka-slf4j" % "2.5.9"
        )
      }
      build.properties
      sbt.version = 0.13.16 

3. Create the Model:

      package com.packt.publishing.wf.persist.model 
      case class WeatherForcastPerHour(city:String, date:String...
