Prepare multi-databases with play framework - database

Question

I want to prepare my application to be compatible with many databases types. To try it i've used H2, MySql and Postgresql. So 'ive added into build.sbt :
"mysql" % "mysql-connector-java" % "5.1.35",
"org.postgresql" % "postgresql" % "9.4-1201-jdbc41"
and i've added conf/prod.conf with all configuration without database configuration, and 3 files:
conf/h2.conf
include "prod.conf"
db.h2.driver=org.h2.Driver
db.h2.url="jdbc:h2:mem:dontforget"
db.h2.jndiName=DefaultDS
ebean.h2="fr.chklang.dontforget.business.*"
conf/mysql.conf
include "prod.conf"
db.mysql.driver=com.mysql.jdbc.Driver
db.mysql.jndiName=DefaultDS
ebean.mysql="fr.chklang.dontforget.business.*"
conf/postgresql.conf
include "prod.conf"
db.postgresql.driver=org.postgresql.Driver
db.postgresql.jndiName=DefaultDS
ebean.postgresql="fr.chklang.dontforget.business.*"
Add to it i've three folders into conf/evolutions with
evolutions/h2
evolutions/mysql
evolutions/postgresql
with these things user can start my application with this command :
-Dconfig.file=dontforget-conf.conf -DapplyEvolutions.default=true -Dhttp.port=10180 &
And this conf file is
include "postgresql.conf"
db.postgresql.url="jdbc:postgresql:dontforget"
db.postgresql.user=myUserName
db.postgresql.password=myPassword
But with this configuration, when my application try to connect to DB :
The default EbeanServer has not been defined? This is normally set via the ebean.datasource.default property. Otherwise it should be registered programatically via registerServer()]]
So i've tried to add, into my configuration :
ebean.datasource.default=postgresql
but when i add it i've :
Configuration error: Configuration error[Configuration error[]]

So i don't understand how i can do it.

Answer 1

YES!!! I've found it! After debug mode (etc...)
There was 2 problems.
First problem : I must add a key into my application.conf :
ebeanconfig.datasource
For me (for exemple), postgresql.conf is modified to :
db.postgresql.driver=org.postgresql.Driver
db.postgresql.jndiName=DefaultDS
ebean.postgresql="fr.chklang.dontforget.business.*"
ebeanconfig.datasource.default=postgresql
Second problem : include into play 2.3.x don't works because conf folder isn't added into classpath (ref Load file from '/conf' directory on Cloudbees ) so we must concat prod.conf, postgresql.conf and dontforget.conf into an only single file.
I hope i have helped any other developper...
