当我想使用 PlayJongo 在 mongodb 中填充数据库时出现错误。

我收到了这个错误

这是我的 build.sbt

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs,
  "uk.co.panaxiom" %% "play-jongo" % "0.9.0-jongo1.2",
  "org.mindrot" % "jbcrypt" % "0.3m",
  "be.objectify" %% "deadbolt-java" % "2.4.3"
)

这是我的 application.conf

play {
  crypto{
    secret = "/;=<kFhD6b]oMNMfNAQt7lqiaw<;u:>jiEFGeSiVd3i?PNL_:ZCI2>jTkywBPMYhhfQo"
  }
  i18n{
    langs = [ "en" ]
  }
  modules {
    enabled += be.objectify.deadbolt.java.DeadboltModule,
    enabled += modules.CustomDeadboltHook
  }
}
  deadbolt {
    java {
      # cache-user is set to false, otherwise it's not possible to mix deadbolt handler that do and don't have users in the template examples
      cache-user=false
    }
  }
playjongo.uri="mongodb://127.0.0.1:27017/play"
playjongo.gridfs.enabled=false
playjongo.defaultWriteConcern="SAFE"

奇怪的是，我得到了错误，但数据仍然更新到数据库中。但我认为数据已损坏，因为我无法使用锁舌处理数据。

我错过了什么吗？也许在配置中，或者我执行错误？
