要求失败：未配置默认日志插件，请参阅'reference.conf'

Question

我在与cassandra一起使用persistentActor时遇到错误，我什至找不到问题所在，甚至在application.conf文件中将cassandra添加为日志。

错误

下面是我的配置文件

cassandrademo{
  akka.persistence.jornal.plugin =  "cassandra.journal"
  akka.persistence.snapshot-store{
    plugin = "cassandra-snapshot-store"
  }
}
我的代码

LocalStoreActor是我的演员

object Postgress extends App{


  val system = ActorSystem("main",ConfigFactory.load().getConfig("cassandrademo"))
  val localstore = system.actorOf(Props[LocalStoreActor],"localstoreactor");
  localstore ! "hello world"
  localstore ! "print"

问题是，Cassandra期望all these configs present in reference.conf。所以要么

• [reference.conf和cassandrademo{与}一起换行-以便可以使用该reference.conf的内容
