Come configurare Slick 3.0.0 per Postgres DB (con Hikari o senza) Typesafe Play conf

Ho un'app di test che funziona bene con un database in memoria H2. Ora sto cercando di collegarlo al nostro vero database. Sto sia sempre un'eccezione Slick interna, o un'eccezione "No driver adatto", a seconda del mio approccio:Come configurare Slick 3.0.0 per Postgres DB (con Hikari o senza) Typesafe Play conf

Ecco la mia semplice test (che, ancora una volta, sembra funzionare bene in-memory):

"The glimple data model classes" should { 
    "insert a glimple row in the database" in { 
     val db = Database.forConfig("db.edb") // works on db.h2mem1 
     val glimples = TableQuery[GPGlimpleModel] 

     val insertGlimples = db.run(glimples += GPGlimple(None, None, 1, true, true, 1)) 

     val count = Await.result(insertGlimples, Duration.Inf) 

     println(count) 
     count must beEqualTo(1) 
     ...

Se accendo il pool di connessioni, come indicato qui:

db.edb = { 
    driver = org.postgresql.Driver 
    url = "jdbc:postgresql://db-server-1.hyrax.com:5444/CI_0" 
    user = "xxx" // masked to protect the innocent 
    password = "xxx" // masked to protect the innocent 
    keepAliveConnection = true 
    // connectionPool = disabled 
}

ho finiscono per ottenere la seguente eccezione. Nel tentativo di decifrare cosa sta succedendo, ho iniziato con un pool di connessioni abilitato (come in, "connectionPool = enabled" o semplicemente commentando quella linea). Ciò ha portato a più problemi ea un'eccezione molto, molto lunga (mostrata alla fine di questo post).

Il capo di tale eccezione è:

[error] [error] java.lang.NoClassDefFoundError: com/zaxxer/hikari/HikariConfig [error] caused by java.lang.ClassNotFoundException: com.zaxxer.hikari.HikariConfig

E che proprio non ha senso per me ... perché ancora una volta, funziona bene in memoria.

Ed ecco la linea del driver build.sbt per Postgres:

"org.postgresql" % "postgresql" % "9.4-1201-jdbc41",

che segue è la completa esclusione ... ho postato a github come suggerito alla fine della traccia:

esempio Lavorare per me:

application.conf

database { 
    dataSourceClass = org.postgresql.ds.PGSimpleDataSource 
    properties = { 
    databaseName = "some_db" 
    user = "local" 
    password = "local" 
    } 
    numThreads = 10 
}

build.sbt

libraryDependencies ++= Seq(
    "com.typesafe.slick" %% "slick" % "3.0.0", 
    "com.zaxxer" % "HikariCP" % "2.4.1", 
    "org.postgresql" % "postgresql" % "9.4-1201-jdbc41", 
    // ... 
)

E poi mi basta chiamare

Database.forConfig("database")

Utilizzo di Java 7, Scala 2.11.6 e 0.13.6 sbt.

Secondo il [HikariCP github] (https://github.com/brettwooldridge/HikariCP#initialization), si dovrebbe importare ** ** HikariCP e non ** HikariCP-java6 ** se stavi usando java 7 o 8. – jlents

@jlents corretto, corretto – sap1ens

Una soluzione con utente di base su application.conf

play.modules.enabled += "modules.DatabaseModule" 

MyNameIs = { 
    database = { 
    driver = org.postgresql.Driver 
    url = "jdbc:postgresql://localhost:5432/databasename" 
    user = "postgreuser" 
    password = "" 
    numThreads = 10 
    connectionTimeout = 5000 
    validationTimeout = 5000 
} 

dispatcher { 
    fork-join-executor { 
    parallelism-factor = 2 
    parallelism-max = 20 
    } 
}

sulla dir applicazione è possibile creare modulo di database come questo

import javax.inject.{Provider, Inject, Singleton} 

import com.google.inject.AbstractModule 
import com.typesafe.config.Config 
import play.api.inject.ApplicationLifecycle 
import play.api.{Configuration, Environment} 
import slick.jdbc.JdbcBackend 

import scala.concurrent.Future 

class DatabaseModule(environment: Environment, configuration: Configuration)  
    extends AbstractModule { 
override def configure(): Unit = { 
    bind(classOf[Config]).toInstance(configuration.underlying) 
    bind(classOf[slick.jdbc.JdbcBackend.Database]).toProvider(classOf[DatabaseProvider]) 
    bind(classOf[models.UserDAO]).asEagerSingleton() 

    } 
} 

@Singleton 
class DatabaseProvider @Inject() (config: Config, lifecycle: ApplicationLifecycle) extends Provider[slick.jdbc.JdbcBackend.Database] { 

    private val db = slick.jdbc.JdbcBackend.Database.forConfig("MyNameIs.database", config) 

    lifecycle.addStopHook {() => 
    Future.successful(db.close()) 
    } 

    override def get(): JdbcBackend.DatabaseDef = db 
}

su App/modelli: UserDAO

import java.sql.Date 
import javax.inject.{Inject, Singleton} 

import com.typesafe.config.Config 
import slick.driver.PostgresDriver.api._ 
import scala.concurrent.Future 
import scala.concurrent.ExecutionContext.Implicits.global 

case class User(id: Option[Long] = None, name: String, firstname: String, email: String, password: String, birthday: Option[Date] = None, signDate: Option[Date] = Some(new Date(System.currentTimeMillis))) 

@Singleton 
class UserDAO @Inject()(config: Config, db: Database) { 


    private val users = TableQuery[Users] 

    override def delete(ids: Long*): Future[Boolean] = { 
    Future.sequence(for (id <- ids) yield { 
     db.run(users.filter(_.id === id).delete).map(_ == 1) 
    }).map { 
     _.find(i => i == false) == None 
    } 
    } 

    def insert(user: User): Future[Unit] = db.run(users += user).map{()} 

    override def update(obj: User): Future[Boolean] = ??? 

    override def create(obj: User): Future[Boolean] = db.run(users += obj).map(_ == 1) 

    override def all: Future[Seq[User]] = db.run(users.result) 

    private class Users(tag: slick.lifted.Tag) extends Table[User](tag, "user") { 


    type S = String 
    type D = Date 
    type L = Long 
    // attribute name in table database 
    def id = column[L](ID, O.AutoInc, O.PrimaryKey) 

    def name = column[S](NAME) 

    def password = column[S](PASSWORD) 

    def firstname = column[S](FIRSTNAME) 

    def email = column[S](EMAIL) 

    def birthday = column[D](BIRTHDAY) 

    def signDate = column[D](SIGN_DATE) 

    override def * = (id.?, name, firstname, email, password, birthday.?, signDate.?) <> ((User.apply _) 
    .tupled, User.unapply _) 
    } 

}

Su controller Application.scala

@Singleton 
class Application @Inject()(userdao: UserDAO) extends Controller { code }

e sulla route file:

# Home page 
GET /       @controllers.Application.index
