playframework - Prepare multi-databases with play framework -

i want prepare application compatible many databases types. try i've used h2, mysql , postgresql. 'ive added build.sbt :

"mysql" % "mysql-connector-java" % "5.1.35", "org.postgresql" % "postgresql" % "9.4-1201-jdbc41" 

and i've added conf/prod.conf configuration without database configuration, , 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 i've 3 folders conf/evolutions with

1. evolutions/h2
2. evolutions/mysql
3. evolutions/postgresql

with these things user can start application command :

-dconfig.file=dontforget-conf.conf -dapplyevolutions.default=true -dhttp.port=10180 & 

and conf file is

include "postgresql.conf"  db.postgresql.url="jdbc:postgresql:dontforget" db.postgresql.user=myusername db.postgresql.password=mypassword 

but configuration, when application try connect db : default ebeanserver has not been defined? set via ebean.datasource.default property. otherwise should registered programatically via registerserver()]]

so i've tried add, configuration :

ebean.datasource.default=postgresql 

but when add i've :

configuration error: configuration error[configuration error[]]         @ play.api.configuration$.play$api$configuration$$configerror(configuration.scala:94)         @ play.api.configuration.reporterror(configuration.scala:743)         @ play.configuration.reporterror(configuration.java:310)         @ play.db.ebean.ebeanplugin.onstart(ebeanplugin.java:56)         @ play.api.play$$anonfun$start$1$$anonfun$apply$mcv$sp$1.apply(play.scala:91)         @ play.api.play$$anonfun$start$1$$anonfun$apply$mcv$sp$1.apply(play.scala:91)         @ scala.collection.immutable.list.foreach(list.scala:383)         @ play.api.play$$anonfun$start$1.apply$mcv$sp(play.scala:91)         @ play.api.play$$anonfun$start$1.apply(play.scala:91)         @ play.api.play$$anonfun$start$1.apply(play.scala:91)         @ play.utils.threads$.withcontextclassloader(threads.scala:21)         @ play.api.play$.start(play.scala:90)         @ play.core.staticapplication.<init>(applicationprovider.scala:55)         @ play.core.server.nettyserver$.createserver(nettyserver.scala:253)         @ play.core.server.nettyserver$$anonfun$main$3.apply(nettyserver.scala:289)         @ play.core.server.nettyserver$$anonfun$main$3.apply(nettyserver.scala:284)         @ scala.option.map(option.scala:145)         @ play.core.server.nettyserver$.main(nettyserver.scala:284)         @ play.core.server.nettyserver.main(nettyserver.scala) caused by: configuration error: configuration error[]         @ play.api.configuration$.play$api$configuration$$configerror(configuration.scala:94)         @ play.api.configuration.reporterror(configuration.scala:743)         @ play.api.db.bonecpapi.play$api$db$bonecpapi$$error(db.scala:271)         @ play.api.db.bonecpapi$$anonfun$getdatasource$3.apply(db.scala:438)         @ play.api.db.bonecpapi$$anonfun$getdatasource$3.apply(db.scala:438)         @ scala.option.getorelse(option.scala:120)         @ play.api.db.bonecpapi.getdatasource(db.scala:438)         @ play.api.db.db$$anonfun$getdatasource$1.apply(db.scala:142)         @ play.api.db.db$$anonfun$getdatasource$1.apply(db.scala:142)         @ scala.option.map(option.scala:145)         @ play.api.db.db$.getdatasource(db.scala:142)         @ play.api.db.db.getdatasource(db.scala)         @ play.db.db.getdatasource(db.java:25)         @ play.db.ebean.ebeanplugin.onstart(ebeanplugin.java:54) 

so don't understand how can it.

yes!!! i've found it! after debug mode (etc...)

there 2 problems.

first problem : must add key application.conf :

ebeanconfig.datasource 

for me (for exemple), postgresql.conf modified :

db.postgresql.driver=org.postgresql.driver db.postgresql.jndiname=defaultds ebean.postgresql="fr.chklang.dontforget.business.*" ebeanconfig.datasource.default=postgresql 

second problem : include play 2.3.x don't works because conf folder isn't added classpath (ref load file '/conf' directory on cloudbees ) must concat prod.conf, postgresql.conf , dontforget.conf single file.

i hope have helped other developper...
