我对幻影非常陌生，我对scala和cassandra有基本的了解。所以我试着用phantom做一个简单的crud例子，所以我在google上看了几个例子。最后我给出了这个例子。但是我运行这个代码不像这个项目自述文件所说的那样。我只是创建了一个intellij项目，有如下主要类。

import org.creative.document.dao.impl.{PhantomConnectorExample}
import org.creative.document.database.SongsDatabase
import org.creative.document.entity.Song

object DocumentAPIMain {

   def main(args: Array[String]): Unit = {

      val song = Song(songId,"Wahinnta Athnam gigum di","Pawana","Nanda Malini")

      val songsDatabase = new SongsDatabase(PhantomConnectorExample.connector)
      songsDatabase.saveOrUpdate(song)

   }

}

这是我所做的唯一改变，除了所有的依赖项和上面提到的链接。
我已经创建了Cassandra键空间，歌曲表和歌曲由艺术家表手动。下面是我的 cassandra ·谢玛

CREATE KEYSPACE phantomtest WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'}  AND durable_writes = true;

CREATE TABLE phantomtest.songs_by_artist (
artist text,
id timeuuid,
album text,
title text,
PRIMARY KEY (artist, id)
) WITH CLUSTERING ORDER BY (id ASC)
AND bloom_filter_fp_chance = 0.01
AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
AND comment = ''
AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy', 'max_threshold': '32', 'min_threshold': '4'}
AND compression = {'chunk_length_in_kb': '64', 'class': 'org.apache.cassandra.io.compress.LZ4Compressor'}
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.1
AND default_time_to_live = 0
AND gc_grace_seconds = 864000
AND max_index_interval = 2048
AND memtable_flush_period_in_ms = 0
AND min_index_interval = 128
AND read_repair_chance = 0.0
AND speculative_retry = '99PERCENTILE';

CREATE TABLE phantomtest.songs (
id timeuuid PRIMARY KEY,
album text,
artist text,
title text
) WITH bloom_filter_fp_chance = 0.01
AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
AND comment = ''
AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy', 'max_threshold': '32', 'min_threshold': '4'}

毕竟，当我运行main方法时，它将以以下错误结束

请帮我找出这个问题。我做错了什么。。。
