Le coeur de l'architecture de Play2 est plutôt simple et reste facile à expliquer dans un article court de blog. Vous pouvez découvrir petit à petit le framework à différents niveaux, et à chaque fois découvrir un peu plus sur certains aspects de son design.
Le coeur de Play2 est vraiment très simple et petit, il est complété par un ensemble d'APIs pratiques, de services et permet de faciliter le développement Web.
De manière simple, Play2 est une API qui abstrait le type suivant :
| package models | |
| import play.libs.WS | |
| import play.api.libs.json.JsValue | |
| import play.api.libs.json.Json._ | |
| import scala.Some | |
| import play.api.libs.EventSource | |
| import org.apache.commons.lang.StringUtils | |
| // Define a generic event, |
| package models | |
| import org.specs2.mutable._ | |
| import play.api.test._ | |
| import play.api.test.Helpers._ | |
| class OriginSpecs extends Specification { | |
| "An Origin" should { | |
| "returns the slug for a valid origin" in { |
| def getOrigin(originId: Long): Option[Origin] = Redis.pool.withClient { | |
| client => | |
| for(slug<-Option(client.hget("Url:From:Rev", originId.toString)); | |
| display<-Option(client.hget("Places:Place:"+originId, "display") | |
| )) yield Origin(originId,display,slug) | |
| } | |
| } |
