ERROR StatusLogger No log4j2 configuration file found [reactivemongo 0.11.7]

[Павел Хандрамай]

I have created a reactivemongo simple app.

import reactivemongo.api.{BSONSerializationPack, MongoDriver}
import reactivemongo.api.commands.Command
import reactivemongo.bson.{BSONArray, BSONDocument}

import scala.concurrent.ExecutionContext.Implicits.global

object TestMongo extends App {

  val driver = new MongoDriver
  val servers = List("localhost:27017")
  val connection = driver.connection(servers)
  val db = connection.db("test")

  val command = BSONDocument(
    "aggregate" -> "test",
    "pipeline" -> BSONArray(
      BSONDocument("$match" -> BSONDocument("foo" -> "bar"))
    )
  )
  val runner = Command.run(BSONSerializationPack)
  runner.apply(db, runner.rawCommand(command)).one[BSONDocument].map(b => println(BSONDocument.pretty(b))).recover {
    case e: Exception => println(e.printStackTrace())
  }

}

build.sbt

name := "Test"

version := "1.0"

scalaVersion := "2.11.7"

resolvers ++= Seq(
  "Sonatype Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots/"
)

libraryDependencies ++= Seq(
  "org.reactivemongo" %% "reactivemongo" % "0.11.7"
)

[info] Running TestMongo 

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

{

  result: [

    0: {

      _id: BSONObjectID("55f01130ad94330a95bfc128"),

      foo: "bar"

    }

  ],

  ok: BSONDouble(1.0)

}

And app is still running. I need press Ctrl+C to exit.

What i'm doing wrong? And what "ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console." ?

You'd better use the ReactiveMongo aggregate framework (rather than RAW command): http://reactivemongo.org/releases/0.11/documentation/advanced-topics/aggregation.html .

I get this code from http://reactivemongo.org/releases/0.11/documentation/advanced-topics/commands.html . And aggregate is just example. Instead it can be "count" command or another one.

ReactiveMongo does not involve the use of RAW command ?

To reproduce not necessary any command. Enough connect to the database.

val db = connection.db("test")

The command API is there to call feature not implemented as operation on database or collection API. Aggregate or count operations are available on collection.

Running the following code with sbt run, the application is shutting down properly.

import scala.concurrent.ExecutionContext.Implicits.global

import reactivemongo.api._

object Main extends App {
  lazy val md = MongoDriver()

  try {
    val con = md.connection(Seq("localhost:27017"))
    con.db("test")
  } finally {
    md.close()
  }
}

Yes, you are right. Sorry, my mistake.
