我刚刚为多个数据库编写了一个测试程序。它基于 hibernate vor 关系数据库和用于 NoSQL 数据库的 hibernate-ogm。

目前我支持 mysql、postgresql 和 MongoDB。现在我想试试 cassandra 驱动程序，但我得到了错误：

'cassandra_experimental' is no valid datastore provider short name. Valid values are: MAP, INFINISPAN, EHCACHE, MONGODB, NEO4J_EMBEDDED, COUCHDB_EXPERIMENTAL

我的 Maven 项目中的依赖项列表：

我使用休眠文档docs.jboss.org

有人已经使用过 cassandra 并且可以在这里提供一些建议吗？

我很感激任何答案:)

PS：更多信息：我在虚拟机中使用 Windows 7 客户端和 ubuntu 14.04 服务器。在我的客户端上，我使用 eclipse 开普勒来编写我的程序。

版本：当我删除 pom.xml 中的版本时，我正在询问错误消息：

我怀疑你没有使用最新的 Hibernate OGM 版本。

从4.2版开始提供 Cassandra 实验性支持。

这是数据存储提供程序名称已更改为 CASSANDRA_EXPERIMENTAL 的提交：6fd5777

您能否删除hibernate-ogm-mongodb和hibernate-ogm-cassandra依赖项的版本，您将从 BOM 中获取它们：

<dependency>
    <groupId>org.hibernate.ogm</groupId>
    <artifactId>hibernate-ogm-mongodb</artifactId>
</dependency>

<dependency>
    <groupId>org.hibernate.ogm</groupId>
    <artifactId>hibernate-ogm-cassandra</artifactId>
</dependency>

您为hibernate-ogm-mongodb指定 4.1.3 ，也许这会引入旧版本的hibernate-ogm-core。如果它仍然不起作用，则需要有关您的环境的更多详细信息：这是 Java SE 还是在诸如 WildFly 之类的 JJ 服务器上？
