com.datastax.driver.core.exceptions.InvalidQueryException：未配置的表schema_keyspaces

Question

我正在尝试使用cassandra配置spring数据。但是当我的应用程序在tomcat中部署时，出现了以下错误。

当我检查连接时，它可用于给定的端口。（127.0.0.1:9042）。我包括波纹管堆栈跟踪和弹簧配置。有人对此错误有想法吗？

全栈跟踪：

问题是Spring Data Cassandra（截至2015年12月，我写这篇文章时）不提供对Cassandra
3.x的支持。这是在freenode上#spring频道中与一位开发人员的对话的摘录：

[13:49] <_amicable>大家好，有人知道spring数据cassandra是否支持cassandra
3.x吗？所有依赖项和datastax驱动程序似乎都是2.x

[13:49] <@_ ollie>友好：不会在不久的将来。

[13:49] <_amicable> _ollie：谢谢。

[13:50] <_amicable>我去看看2.x与3.x的相对优点；然后；）

[13:51] <@_ ollie> SD Cassandra（到目前为止）是一个社区项目，其进展很大程度上取决于开发人员可以实际花多少时间。

[13:51] <@_ ollie>我们将在2016年2月邀请某人加入团队，以使该项目与Spring Data核心项目更加紧密地契合。
