scala - Firebase Java SDK doesn't persist data and doesn't trigger callback. Tasks seems never complete -


i'm trying write data on firebase based on guide https://firebase.google.com/docs/database/server/start , using play framework + scala.

after call databasereference.setvalue nothing happens: data isn't persisted on firebase , callback not triggered.

here's code:

  lazy val conf = configfactory.load()    lazy val options = new firebaseoptions.builder()                                         .setcredential(firebasecredentials.fromcertificate(new fileinputstream(conf.getstring("firebase.credentials.path"))))                                         .setdatabaseurl("https://orsz-xxxxx-xxxxx.firebaseio.com/")                                         .build()    lazy val propsdb = firebasedatabase.getinstance().getreference()    /** initialize block instantiates firebaseapp **/   {     println("[firebasepersistence] - initialize firebaseapp")     firebaseapp.initializeapp(options)     firebasedatabase.getinstance().setloglevel(logger.level.debug)     println("[firebasepersistence] - initialize firebaseapp done!")   }    def persistproposition(prop: proposition): future[proposition] = future {     val task = propsdb.setvalue(1, new databasereference.completionlistener() {       override def oncomplete(databaseerror: databaseerror, databasereference: databasereference) {         if (databaseerror != null) {           println("error: " + databaseerror.getmessage)         } else {           println("[firebasepersistence.persistproposition] - ok")         }       }     })     prop   }

i can see, testing on sbt console, task generated on setvalue never completes after seconds:

scala> task.iscomplete  res6: boolean = false

executing firebase log level debug log:

i can see permission denied on log can't figure out why.

i test credentials on fileinputstream , ok.

the permission on firebase project:

{   "rules": {     ".read": "true",     ".write": "true"   } }

i test using firebase-admin-4.1.6 , firebase-server-sdk-3.0.1 , have same result

edit: printed firebaseapp, firebasedatabase , databasereference objets before call setvalue , got lines above. how may ensure admin sdk initialized correctly?

firebaseapp=firebaseapp{name=[default], options=firebaseoptions{databaseurl=https://orsz-xxxxx-xxxxx.firebaseio.com/, credential=com.google.firebase.auth.firebasecredentials$certcredential@558b77e8, databaseauthvariableoverride={}}} firebaseapp.name=[default]  firebasedatabase.getinstance()=com.google.firebase.database.firebasedatabase@124cb42b  databasereference=https://orsz-xxxxx-xxxxx.firebaseio.com/12345

i tested new project , admin sdk version 4.1.6.

with java code:

final firebasedatabase database = firebasedatabase.getinstance(); databasereference ref = database.getreference("43256111"); ref.setvalue(1, new databasereference.completionlistener() {     @override     public void oncomplete(databaseerror databaseerror, databasereference databasereference) {         if (databaseerror != null) {             system.err.println(databaseerror);         } else {             system.out.println("written");         }     } });

the 43256111 location in database used testing.

i after few seconds:

written

the rules don't matter in case, since admin sdk runs administrative privileges by-passes these rules me:

"43256111": {   ".write": false }

so i'm not sure what's going on in case, can't reproduce it. sure have admin sdk initialized correctly?

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
