Java 无法使用spring批处理写入cassandra表

我正在编写一个spring批处理过程，从cassandra表中读取数据并对其进行修改，然后将数据写回cassandra表。我使用同一个类将数据读写回表。我的作业写在一个xml文件中，我正在运行该xml文件本身。我遇到以下错误： 当我试图将ArrayList写回表时，会显示错误

org.springframework.data.cassandra.mapping.VerifierMappingExceptions： java.util.ArrayList:Cassandra实体必须具有@Table， @永久或@PrimaryKeyClass注释

它还显示了

位于org.springframework.data.cassandra.mapping.BasicAssandrapersistentyMetadataVerifier.verify（BasicAssandrapersistentyMetadataVerifier.java:45） 位于org.springframework.data.cassandra.mapping.basicassandrapersistenty.verify（basicassandrapersistenty.java:198）

嗨，伙计们！希望使用SpringBatch通过SpringDataCassandra将数据存储到Cassandra，但我也希望能够存储我的作业配置。不幸的是，我不能同时拥有（sql和无sql）dbs。在过去的两年里，某物发生了变化？
