Akka持久化和Mongodb: persistenceId回放事件持久化失败

Question

我正在使用mongodb的akka-persistence，使用这个mongodb插件。当我运行我的代码时，我得到了以下错误：

[ERROR] [11/19/2016 16:47:29.355] [transaction-system-akka.actor.default-dispatcher-5] [akka://transaction-system/user/$a] Persistence failure when replaying events for persistenceId [balanceTransactions]. Last known sequence number [0] (akka.persistence.RecoveryTimedOut)

我不明白这个错误是什么意思，以及我如何解决这个错误。以下是我的reference.conf文件：

akka {
  persistence {
    journal {
      plugin = "casbah-snapshot"
    }
    snapshot-store {
      plugin = "casbah-snapshot"
    }
  }
}

casbah-snapshot {
  mongo-url = "mongodb://localhost:27017/user.events"
  woption = 1
  wtimeout = 10000
  load-attempts = 5
}

Answer 1

更改我的reference.conf文件后，我的示例成功工作。下面是有效的reference.conf文件。

akka {
  stdout-loglevel = off // defaults to WARNING can be disabled with off. The stdout-loglevel is only in effect during system startup and shutdown
  log-dead-letters-during-shutdown = off
  loglevel = info
  log-dead-letters = off
  log-config-on-start = off // Log the complete configuration at INFO level when the actor system is started

  loggers = ["akka.event.slf4j.Slf4jLogger"]
  logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"

  persistence {
    journal {
      plugin = "casbah-journal"
    }
  }
}

casbah-journal {
  mongo-url = "mongodb://localhost:27017/transaction.events"
  woption = 1
  wtimeout = 10000
  load-attempts = 5
}
