我正试图将我的spring引导应用程序连接到aws keyspaces，我已经尝试了aws帮助手册中提到的每一步，但我仍然无法连接，任何关于如何实现上述功能的见解都是值得赞赏的。
我已经列出了下面的配置代码，库和异常
CassandraConfig.java

return CqlSession.builder().
withConfigLoader(loader).

任何关于如何实现连接的见解都是非常感谢的。由于
这可能是你的连接，这里有一个Github示例，关于如何使用Spring连接到Keyspaces。
但是为了获得更好的表的可观察性。这是一个Github存储库，它将使用CloudFormation模板设置CloudWatch指标。这些指标将为您提供更多的可见性，以确保它不是容量问题，它确实是一个连接问题。
application.conf可能正在为SSLEngineFactory创建问题。在以下示例中，在AWS Keyspaces Connection
中检查本地数据中心的值格式datastax-java-driver {
basic.contact-points = ["cassandra.us-east-2.amazonaws.com:9142"]
basic.load-balancing-policy {
class = DefaultLoadBalancingPolicy
local-datacenter = us-east-2
}
advanced {
auth-provider = {
class = software.aws.mcs.auth.SigV4AuthProvider
aws-region = us-east-2
}
ssl-engine-factory {
class = DefaultSslEngineFactory
truststore-path = "./src/main/resources/cassandra_truststore.jks"
truststore-password = "my_password"
}
}
