jpa с подключением db mysql не работал в lagom

0 голосов
/ 20 декабря 2018

Я создал проект lagom и подключился к базе данных MySQL с сохранением jpa.Мои файлы конфигурации находятся ниже.Когда я запускаю эту кодовую таблицу, она не была создана в БД, и она отображает ошибку:Пожалуйста, помогите мне.

Эта ошибка появляется через несколько секунд, я не знаю, чего мне не хватает в этом коде.

Ошибка 

 akka.pattern.AskTimeoutException: Ask timed out on [Actor[akka://rdapupdate-impl-application/user/jd
 bcCreateTables-singleton/singleton/jdbcCreateTables#-898354221]] after [20000 ms]. Message of type [com.lightbend.lagom.internal.persistence.cluster.ClusterStartupTaskActor$Execute$] was sent by [Actor[akka://rdapupdate-impl-application/user/jdbcCreateTables-singleton/singleton/jdbcCreateTables#-898354221]]. A typical reason for `AskTimeoutException` is that the recipient actor didn't send a reply.
