Play 2.6 reactivemongo multiple database

In your Play application, you can use ReactiveMongo with multiple connection pools (possibly with different replica sets and/or different options), using the @NamedDatabase annotation.

Consider the following configuration, with several connection URIs.

# The default URI
mongodb.uri = "mongodb://someuser:somepasswd@localhost:27017/foo"

# Another one, named with 'bar'
mongodb.bar.uri = "mongodb://someuser:somepasswd@localhost:27017/lorem"
Then the dependency injection can select the API instances using the names.

import javax.inject.Inject

import play.modules.reactivemongo._

class MyComponent @Inject() (
  val defaultApi: ReactiveMongoApi, // corresponds to 'mongodb.uri'
  @NamedDatabase("bar") val barApi: ReactiveMongoApi // 'mongodb.bar'
) {

}
