hibernate-ogm - 'cassandra_experimental‘不是有效的数据存储提供者短名称。

Question

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NoSQL数据库hibernate-ogm .

目前，我支持mysql、postgresql和MongoDB。现在我想试试卡桑德拉的驱动程序，但我发现了一个错误：

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

我使用hibernate文档docs.jboss.org

有人已经用过卡桑德拉了，可以在这里给你一些建议吗？

谢谢你的回答:)

PS:更多信息:我在虚拟机中使用windows 7客户端和ubuntu14.04服务器。在我的客户端，我用eclipse开普勒编写我的程序。

版本:当我删除pom.xml中的版本时，我想知道错误消息：

Answer 1

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

<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指定了4.1.3，这可能是hibernate-ogm-core的旧版本。如果它仍然不能工作，那么您的环境需要更多的细节:这是Java还是在JJ服务器(如WildFly )上？

Answer 2

我怀疑你没有使用最新的Hibernate OGM版本。

卡桑德拉实验支持可以从4.2版本开始。

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