Mysterious Play 2.4 Injection exception

Question

Recentemente aggiornato a Play 2.4 e sto ancora imparando tutte le piccole stranezze e così via. Sto provando a far funzionare la mia pagina indice e sto attraversando un periodo difficile, e so che è una cosa piccola che mi manca. Qui è l'errore

CreationException: Unable to create injector, see the following errors: 

1) Error in custom provider, Configuration error: Configuration error[Cannot connect to database [default]] 
    while locating play.api.db.DBApiProvider 
    while locating play.api.db.DBApi 
    for parameter 0 at play.db.DefaultDBApi.<init>(DefaultDBApi.java:28)

    at com.google.inject.util.Providers$GuicifiedProviderWithDependencies.initialize(Providers.java:149) 
    at play.db.DBModule.bindings(DBModule.java:40): 

e le mie informazioni di configurazione (sì che il numero di porta per MySQL è corretto)

application.conf

db.default.driver=com.mysql.jdbc.Driver 
db.default.url="jdbc:mysql:localhost:33060/coffee_bean" 
db.default.username= 
db.default.password="" 
ebean.default = ["models.*"] 

regolatore principale

public Result index() { 
     ObjectNode response = Json.newObject(); 
     Configuration config = Play.application().configuration(); 
     response.put(config.getString("coffee.bean.message.key"),config.getString("coffee.bean.success.message")); 
     response.put(config.getString("version"), config.getString("coffee.bean.version")); 

     return ok(response); 
    } 

costruito. sbt

name := """coffee-bean""" 

version := "1.0-SNAPSHOT" 

lazy val root = (project in file(".")).enablePlugins(PlayJava)

addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0") 

// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using 
// enablePlugins(SbtEbean). Note, uncommenting this line will automatically bring in 
// Play enhancer, regardless of whether the line above is commented out or not. 
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0") 
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.0") 

Tutto il resto hai bisogno di vedere?

Finora ho provato solo a reimportare le dipendenze, ricontrollare per assicurarsi che la versione sia corretta, ripassare la documentazione e finora nulla ha funzionato. Mi aspetto che un determinato utente abbia tutte le risposte :)

Answer 1

Database connection configuration mancante.

definirlo in conf\application.conf:

db.default.driver=com.mysql.jdbc.Driver 
db.default.url="jdbc:mysql://localhost/playdb" 
db.default.username=playdbuser 
db.default.password="a strong password" 

Answer 2

mio config:

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
      xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" 
      version="2.1"> 

    <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL"> 
     <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
     <non-jta-data-source>caribbeanDS</non-jta-data-source> 
     <properties> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/> 
      <property name="hibernate.hbm2ddl.auto" value="update"/> 
     </properties> 
    </persistence-unit> 

</persistence> 

Il mio codice:

version := "1.0-SNAPSHOT" 

lazy val root = (project in file(".")).enablePlugins(PlayJava) 

scalaVersion := "2.11.6" 

libraryDependencies ++= Seq(
    javaJdbc, 
    cache, 
    javaWs, 
    javaJpa, 
    "org.hibernate" % "hibernate-entitymanager" % "4.3.10.Final" // replace by your jpa implementation 
) 


// Play provides two styles of routers, one expects its actions to be injected, the 
// other, legacy style, accesses its actions statically. 
routesGenerator := InjectedRoutesGenerator 


fork in run := true
