Firebase Java SDK不會保留數據，也不會觸發回調。任務似乎從未完成

我正在嘗試根據本指南https://firebase.google.com/docs/database/server/start並使用Play Framework + Scala在Firebase上編寫一些數據。Firebase Java SDK不會保留數據，也不會觸發回調。任務似乎從未完成

調用DatabaseReference.setValue後沒有任何反應：數據未保留在Firebase上，我的回調未觸發。

下面的代碼：

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 to 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 
    }

我可以看到，測試SBT控制檯上，上的setValue生成的任務無法完成，即使秒後：

scala> task.isComplete 
res6: Boolean = false

與火力地堡日誌級別DEBUG我執行得到這個日誌：

我可以看到一些權限拒絕日誌，但可以'弄清楚爲什麼。

我已經在FileInputStream上測試憑據，它是可以的。

在火力地堡項目的權限：

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

我已經測試使用火力管理員-4.1.6和火力服務器-SDK-3.0.1，並有同樣的結果

編輯：我在調用setValue之前打印了FirebaseApp，FirebaseDatabase和DatabaseReference對象，並獲得了上面的代碼。我如何確保admin sdk被正確初始化？

FirebaseApp=FirebaseApp{name=[DEFAULT], options=FirebaseOptions{databaseUrl=https://orsz-xxxxx-xxxxx.firebaseio.com/, credent[email protected]558b77e8, databaseAuthVariableOverride={}}} 
FirebaseApp.name=[DEFAULT] 

FirebaseDatabase.getInstance()[email protected] 

DatabaseReference=https://orsz-xxxxx-xxxxx.firebaseio.com/12345

看到我下面的後續。不是一個真正的答案，但太長的評論。 –

我剛剛測試了一個新項目和Admin SDK版本4.1.6。

有了這個Java代碼：

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"); 
     } 
    } 
});

的43256111是我的數據庫，我用於測試的位置。

我得到這個幾秒鐘後：

書面

規則沒有即使在這種情況下無所謂，因爲管理員SDK具有管理權限運行，甚至繞過這些規則對我來說：

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

所以我不知道發生了什麼事，你的情況，但我不能複製。你確定你有管理SDK初始化正確嗎？

我編輯我的問題，並提供了一些關於「我如何確保admin sdk被正確初始化的信息？」 –

Firebase Java SDK不會保留數據，也不會觸發回調。任務似乎從未完成
