我是scala的新手，我会运行一个简单的查询来从scylla检索一些数据。这是我的密码：

val my_name = "test"
val cluster = ScyllaConnector.getCluster(clusterIpString, scyllaPreferredDc, scyllaUsername, scyllaPassword)
val session = cluster.connect(keySpace)
val preparedStatement: PreparedStatement = session.prepare(GOID_QUERY)
val nameResults = session.execute(preparedStatement.bind(my_name))
val nameResult = nameResults.one()
if(nameResult != null){
  println("Here")
  val id_recent = nameResult.getSet("id_recent",  classOf[String])
  println(id_recent)
}
session.close()
cluster.close()

抛出：

我相信问题会在未来几年出现 getSet 在要求的地方排队 classOf[String] 但我不知道用什么来代替它。
以下是我的表定义：

-- auto-generated definition
create table name_table
(
    name       text,
    id_recent  text,
    primary key (name)
)
