Did someone resolve this problem ? 回答1: This Messages.scala source code has a clue: protected val messagesPrefix = config.getDeprecated[Option[String]]("play.i18n.path", "messages.path") I have not tried it in 2.4 yet, but it looks worth taking for a spin. 回答2: You can specify the sub-directory in application.conf by

问题 I'm currently having an issue with a Finder instance in Play 2.4 whereby it returns a null pointer exception when used. Here is the code trying to use it public ExpressionList<ClientAuthorization> getAuthorizationQuery(String appId) { return ClientAuthorization.find.where().eq("app_id", appId).eq("active", 1); } And the model class package models; import com.avaje.ebean.Model; import javax.persistence.*; import java.sql.Timestamp; @Entity @Table(name="client_authorization") public class

问题 I'm trying to insert a List[String] into a postgresql column of type text[]. I believe when you attempt to insert any List, Anorm inserts each member of the List in its own column. I'm pretty sure this is the case because I get back the exception: org.postgresql.util.PSQLException: ERROR: INSERT has more expressions than target columns What I want to do is insert the entire List as a text[]. My current code: def insertList(listName: String, subLists: List[String]): Long = { DB.withConnection
