我无法使用spring-boot版本2.3.0.RELEASE与datastax cassandra实例建立连接。同样的代码适用于spring-boot2.6版本
运行春季启动应用程序时出错

我不确定这是否是同一个问题https://github.com/spring-projects/spring-boot/issues/21487这个问题说它是在弹簧靴的2.3.1版本中修复的，但如果我使用2.3.1版本，我会遇到同样的例外。
Andrew的评论是正确的。问题是，安全连接捆绑包包含连接元数据和SSL(TLS(凭据，因此驱动程序已经期望启用加密，这就是解析程序抛出此异常的原因：
nested exception is java.lang.IllegalStateException:
Can't use withCloudSecureConnectBundle and explicitly specify ssl configuration.
They are mutually exclusive.
您可以通过从application.properties:中删除此行来解决冲突
spring.data.cassandra.ssl=true
我不熟悉Spring的代码库，所以我无法验证为什么它在2.6中有效，而在2.3中无效。
这要归功于Cédric Lunven在这个问题上的建议。干杯
