如何在 Spring Data Cassandra XML 配置中设置一致性级别

Question

我正在使用 Spring-Data-Cassandra 1.2.2。我正在使用 XML 配置如下。我读到默认的 ConsistencyLevel 是 ONE，我想将它设置为 QUORUM。我如何在 XML 中配置它？如果需要，我可以升级我的 Spring-Data-Cassandra 版本。

<?xml version='1.0'?>

</beans>

似乎 JavaConfig 是唯一的解决方案。事实证明，从 1.2.2 升级到 1.5 有点复杂，因为我项目中的其他 spring-data(mongo & JPA) 依赖项。所以我在 1.2.2 版本中使用了以下配置：com.datastax.driver.core.Cluster.builder().withQueryOptions(‌new QueryOptions().setConsistencyLevel(ConsistencyLevel.QUORUM))
