问题 My logging is working fine from within my play code, but the akka code I have isn't logging to file/stdout. class EmailActor extends Actor with ActorLogging { import EmailActor._ log.info("email actor hatched..") ... } When I create this actor I don't see the logging entries in either the log file or stdout. I have the default application.conf from this activator template: https://github.com/playframework/play-scala/blob/master/conf/logback.xml Do I need to modify my logback file with some

问题 I am working on a project using PlayFramework 2.0. After reading a bit of scala I would like to embed some dynamic code in the View template. So, I did the following: @{ def getMystring(sequence:Int) = { if(patternForm != null && patternForm.get().windowTreatments != null && patternForm.get().windowTreatments.size() >= sequence + 1) sequence+"" else "" } } <input type = "text" value = @getMystring(1)></input> ... I was quite sure it was going to work but instead I got a "not found: value

问题 I'm trying to use "org.apache.mahout" % "mahout-integration" % "0.7" as a dependency inside my play2 based web application.

问题 I had a spelling mistake in the conf/routes file which caused incorrectly named classes to be generated by Play Framework. Rebuilding project and even running Invalidate Caches does not solve the problem in IntelliJ. The incorrect class files were re-generated when I manually run play clean from the command line. Is there an equivalent of Build Clean for Play Framework projects in IntelliJ? 回答1: You can either cd to the project and run play clean compile or create a run configuration to make

问题 I have this in my "routes" file: POST /accounts/ controllers.AccountsController.createOneAccount And in my AccoutsController.java: package controllers; import com.google.inject.Inject; import play.Application; import play.mvc.Controller; import play.mvc.Result; import services.AccountService; import java.io.IOException; public class AccountsController extends Controller { @Inject private Application application; final String host = application.configuration().getString("db.default.host");

问题 I have a static file that I want to read in one of my Play Framework models. The file contains some simple text in it. I can't find any examples or API that shows where the appropriate location is to store such a resource and second, how to access that resource. For whatever it is worth I'm using Play for Scala, but I don't think that's relevant here. 回答1: You can place any resource file in the folder /conf and load it (Programatically) as explained here: Custom configuration files - Play!
