Wie spielen Rahmenstartfehler

Question

Datenbankverbindungsfehler

Im folgenden Stacktrace, nur die erste Zeile im Spiel im Produktionsmodus angemeldet sind nicht zur Anmeldung: [info] Anwendung - Erstellen von Pool für Datenquelle ‚default‘ geht auf der Anwendung .Log. Die Ausnahme wird nur auf stderr in play.core.server.RealServerProcess#exit

gedruckt Ich könnte http://projects.lidalia.org.uk/sysout-over-slf4j/quickstart.html verwenden, aber es kann nicht in der Anwendung onStart als Datenbankverbindung passieren, bevor geschehen, so brauche ich vielleicht ein Modul schreiben?

https://www.playframework.com/documentation/2.4.x/JavaDependencyInjection

subclassed GuiceApplicationLoader und es funktioniert

play.application.loader = "modules.LogSdtErrLoader" 

LogSdtErrLoader.scala

package modules 

import play.api.ApplicationLoader 
import play.api.inject.guice.{GuiceApplicationBuilder, GuiceApplicationLoader} 
import uk.org.lidalia.sysoutslf4j.context.SysOutOverSLF4J 

class LogSdtErrLoader extends GuiceApplicationLoader { 

    override final def builder(context: ApplicationLoader.Context): GuiceApplicationBuilder = { 
    SysOutOverSLF4J.sendSystemOutAndErrToSLF4J() 
    super.builder(context) 
    } 
}
