无法将 Java Spring 引导应用程序连接到 Amazon Keyspaces

Question

我正在尝试将我的 java spring 引导应用程序连接到我的 AWS Keyspaces 密钥空间。 I've followed amazons docs on how to setup and configure this connection using the DataStax Java Driver for Apache Cassandra ( https://docs.aws.amazon.com/keyspaces/latest/devguide/using_java_driver.html ). 我还查看了以下内容：

1. 不支持使用 Amazon Keyspaces 的分区程序（对于 Apache Cassandra）
2. 使用 Spring 反应数据自动配置连接到 AWS 键空间
3. https://docs.spring.io/spring-data/cassandra/docs/3.2.0/reference/html/#cassandra.connectors

这是我收到的错误：

它还会一遍又一遍地打印以下警告，直到引发上述错误：

我还为 com.datastax.oss 依赖项尝试了 4.9.0 和 4.11.0 版本

应用程序.conf

datastax-java-driver {
     basic.contact-points = ["cassandra.us-east-2.amazonaws.com:9142"]
     advanced.auth-provider {
         class = PlainTextAuthProvider

         password = "******"
     }
     basic.load-balancing-policy {
         local-datacenter = "us-east-2"
     }
     advanced.connection {
         timeout = 30 seconds
         connect-timeout = 30 seconds
         init-query-timeout = 30 seconds
      }

     advanced.metadata {
         schema.enabled = "false"
         token-map.enabled = "false"
     }

     advanced.ssl-engine-factory {
         class = DefaultSslEngineFactory

         truststore-path = "./src/main/resources/cassandra_truststore.jks"
         truststore-password = "****"
     }
 }

cassandra 配置 class：

}

无论我尝试什么，我都会继续遇到同样的错误。 任何和所有的帮助将不胜感激。

Answer 1

该问题看起来与您使用的证书有关

这是线索：

"javax.net.ssl.SSLHandshakeException: No subject alternative names matching IP address 3.12.23.15"

看看这个： Java CertificateException“没有与 IP 地址匹配的主题替代名称......找到”

Answer 2

来自 AWS Keyspaces 的错误消息会误导超时。 真正的问题是驱动程序的 ssl-engine-factory 配置为默认值 - 无。 请参阅： https://docs.datastax.com/en/developer/java-driver/4.13/manual/core/ssl/

当使用 spring 配置AbstractReactiveCassandraConfiguration时， datastax 配置标准行为被覆盖并且不起作用。

AbstractSessionConfiguration class（由AbstractReactiveCassandraConfiguration扩展）中的方法getSessionBuilderConfigurerWrapper仅将驱动程序类型安全配置定义为 defaultOverrides（它们是系统属性）和 defaultReference（它是“reference.conf”）。

因此，为了应用您的配置，您应该覆盖AbstractSessionConfiguration class 中的getDriverConfigurationResource并将其作为Resource返回。
