问题 The link here shows you how to configure your custom logger. https://www.playframework.com/documentation/2.4.x/SettingsLogger I was just wondering where is the ${applicaation.home} defined, as it seems to not have been defined in my production environment. 回答1: As indicated by @user316607, Play should define application.home by itself in the Logger.configure method. If you are seeing the value application.home_IS_UNDEFINED instead, and you're using compile-time dependency injection, you'll

问题 I am trying to make a call from a Play Java class to a Scala method which takes a ClassTag as a parameter My failing attempt is Option<LocalUser> localUser = Cache.getAs(userId.userId(), app, new ClassTag<LocalUser>() ); The API method looks like this Cache.getAs(String key, Application app, ClassTag<LocalUser> ct ); 回答1: I had the same issue when calling a different Scala API from Java. You'd use: ClassTag<LocalUser> tag = scala.reflect.ClassTag$.MODULE$.apply(LocalUser.class); I'm not sure

问题 using publishTo in build.sbt file, it can be automation the publishing progress. But asset files( in public folder) does not packaged. how to package and publish asset files? 回答1: For locally publishing assets files , add this snippet in build.sbt file import play.PlayImport.PlayKeys._ packagedArtifacts in publishLocal := { val artifacts: Map[sbt.Artifact, java.io.File] = (packagedArtifacts in publishLocal).value val assets: java.io.File = (playPackageAssets in Compile).value artifacts +

问题 Using Play 2.3 (Java), I'd like to use a parameter from application.conf as a value for a constraint. Something like: public class Some { @Constraints.MaxLength(Play.application().configuration().getInt("some.text.maxlength", 1000)) public String text; } But of course I can't do this because the annotation parameter must be a constant. What would be the approach, in Java, to bypass this? Should I use a custom validator? Or is there another option? Any help appreciated. 回答1: As you discovered

问题 I want to write a custom Constraint to use it in my Form for validation. Mappings in Form have a verifying function: verifying (constraints: Constraint[T]*): Mapping[T] . I can obviously use the built in constraints, e.g. "name" -> text.verifying(nonEmpty) . Now I need my own constraint though. The Constraint case class looks like: case class Constraint [-T] (name: Option[String], args: Seq[Any], f: (T) ⇒ ValidationResult) extends Product with Serializable But when I looked at

问题 I have this on my app/scripts folder (I created this folder inside app/ ). I'm not sure how I can properly set the classpath here, thus I didn't even run this to know if it will actually connect to the database. How can I run this in a clean way from the command line? package scripts import scala.collection.TraversableOnce import scala.collection.generic.SeqForwarder import scala.io.Source import scala.slick.jdbc.{StaticQuery => Q} import scala.slick.session.Session import scala.slick.session

问题 I'm trying to get a Play 2.2 project to work with Hibernate JPA and a PostgreSQL database. I did it before with Play 2.1.1, where it worked perfectly. I get the following error now: play.api.UnexpectedException: Unexpected exception[NoClassDefFoundError: org/w3c/dom/ElementTraversal] at play.core.ReloadableApplication$$anonfun$get$1$$anonfun$apply$1$$anonfun$1.apply(ApplicationProvider.scala:152) ~[play_2.10.jar:2.2.0] I have no idea where this comes from. My build.sbt looks like this:

问题 I'm using play 2.0.4 with Java. I'm trying to save and retrieve a value from the in-memory db that play provides (Ebean is the underlying JPA implementation). Here's some sample code: @NoobDisclaimer ("I'm fairly new to Play and JPA") @Entity public class User extends Model { @Id public Long id; public String name; // Does not fetch eagerly. @ManyToOne(fetch=FetchType.EAGER) private Role role; // Role extends Model { has id and name} public static Finder<Long, User> find = new Finder<Long,

问题 My Play 2.1.1 project uses SBT 0.12.3, and when compiling it on my dev machine, everything's fine, I get no errors, and the app runs without any issues. When I try to compile it on an EC2 instance used for testing, I get the superlong error message below. The only possibly relevant difference between the two environments is that I have java 6 (1.6.0_45) on my dev machine, and java 7 (1.7.0_19) on EC2, but I can't currently change neither. Have you ever seen something like this? What can this

问题 While working on a French app (french language is full of single quotes), I needed to use i18n with single quotes and many other accentuated chars. So here is an extract of my messages.fr-FR file : some.key=C'est la vie! And here is the output : Cest la vie! How can I use strings containing single quotes in my messages? Already tried those : some.key=C\'est la vie! --> C\est la vie! some.key="C'est la vie!" --> "Cest la vie!" EDIT : Thanks to the link KDavid gave I was able to find the
