Question

我们通过 SSL 使用cassandra-driver-core-2.1.9从Wildfly 10本地连接到Cassandra 2.2.2（在Centos 7.1上，两个单独的服务器，防火墙关闭）。一切似乎都有效，但服务器不断生成以下警告（Wildfly服务器日志）：

当我们在没有SSL的情况下完全相同时，没有警告。其他版本的cassandra驱动程序或netty不做任何更改。 CQLSH没有问题。如果我们从普通的Java SE应用程序中做到完全相同，也没有问题。所以我认为它与Java bean生命周期有一些共同点，但是我找不到问题。

cassandra.yaml 中的相关设置：

server_encryption_options:
    internode_encryption: all
    keystore: /etc/pki/cassandra/keys/.keystore
    keystore_password: password1
    truststore: /etc/pki/cassandra/certs/.truststore
    truststore_password: password1
    # More advanced defaults below:
    # protocol: TLS
    # algorithm: SunX509
    # store_type: JKS
    # cipher_suites: [TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_12
    require_client_auth: false

# enable or disable client/server encryption.
client_encryption_options:
    enabled: true
    keystore: /etc/pki/cassandra/keys/.keystore
    keystore_password: password1
    require_client_auth: false
    # Set trustore and truststore_password if require_client_auth is true
    truststore: /etc/pki/cassandra/certs/.truststore
    truststore_password: password1

感谢您的帮助。

我在一个项目上遇到了同样的问题，添加了io.netty：netty-all依赖解决了它，所以netty是根本原因。

无法初始化类io.netty.handler.time out.IdleStateEvent
