我正在尝试使用cassandra db将shedlock集成到我的春靴项目中。
但我在应用程序启动时收到以下错误。

2022-11-18 17:35:29,162 [main] ERRR o.s.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'lockProvider'

Cassandra脚本已执行

CREATE KEYSPACE shedlock with replication={'class':'SimpleStrategy', 'replication_factor':1} and durable_writes=true;
CREATE TABLE shedlock.lock (name text PRIMARY KEY, lockUntil timestamp, lockedAt timestamp, lockedBy text);

我已经通过cqlsh验证了锁表是在cassandra中创建的。
到目前为止，我认为的问题是，由于某种原因，CqlSession bean不可用，而且应该是可用的。
我已经尝试了官方文档页面中提到的配置。
我尝试过将Springboot和shedlock的版本降级，但是没有用。Springboot版本更改2.5.x（相同错误）2.2.13.RELEASE（相同错误）2.3.x（相同错误）
