使用Scala的Kryo的HazelcastSerializationException

我正在使用kryo与Scala 2.11.1和Hzaelcast 3.5进行序列化我试图将我的数据放入hazelcast Map 但我得到了KryoException

这是我的模特课

@SerialVersionUID(1)
        case class User( id : Int ,name : String, userType : UserType /*UserType is Enum (EMPLOYED , UNEMPLOYED)*/ , userhistory : UserHistory) extends  Serializable{

def this()= {
this(0,"",Active, null)
}
}

这是 UserHistory 类

@SerialVersionUID(1)
case  class UserHistory( date : DateTime = DateTime.now(), artworkStatus : ArtworkStatus = ACTIVE) extends  Serializable{

def this()={
    this(DateTime.parse("0"),ACTIVE) 
  }
}

这是我的User类的序列化器

class UserSerializer extends StreamSerializer[User] {


   val log = LoggerFactory.getLogger(this.getClass)

   override def destroy() {

  }

  override def getTypeId() : Int ={
    val value : Int = 1;
    value

  }

  // takes the bytes and converts into User Object
   @throws(classOf[IOException])
  override def read(in : ObjectDataInput) : User =  {

     val kryo = new Kryo 
     val input = new Input(in.asInstanceOf[InputStream])
      log.info("********** Reading the bytes and converting into User object")
     kryo.readClassAndObject(input).asInstanceOf[User]



  }

   // takes User Object and converts into bytes
  @throws(classOf[IOException])
  override def write(out : ObjectDataOutput, obj : User) {

    val kryo= new Kryo
    val bops = new ByteArrayOutputStream
    val output = new Output(bops)
    kryo.writeClassAndObject(output , obj)
    output.flush
    output.close

    bops.writeTo(out.asInstanceOf[OutputStream])

    log.info("********** User object writen into bytes successfully")


  }


}

现在，当我将来自Hcast客户端的User类对象放入相应的 Map 中时，就像这样

map.set(user.id , user)

它给了我这些例外：
