我正在尝试使用Mongodb和Morphia将数据放入datastore并且它给了我一个错误：
Exception in thread "main" java.lang.IllegalArgumentException: clusterListener can not be null

整个代码
companion object {
lateinit var client: MongoClient
lateinit var morphia: Morphia
lateinit var datastore: Datastore
}
init {
client = MongoClient("localhost", 27017)
morphia = Morphia()
datastore = morphia.createDatastore(client, "teste")
}
我不知道如何解决这个问题，有人可以帮忙吗？
