hibernate-ogm

Question

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

目前我支持mysql、postgresql 和MongoDB。现在我想试用 cassandra 驱动程序，但出现错误：

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

我的maven项目中的依赖列表：

我使用休眠文档 docs.jboss.org

有没有人用过cassandra，可以给点建议吗？

感谢任何回答:)

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 kepler 来编写我的程序。

版本：当我删除 pom.xml:

中的版本时，我被要求提供错误消息

Answer 1

我怀疑您使用的不是最新的 Hibernate OGM 版本。

从版本 4.2 开始提供 Cassandra 实验性支持。

这是数据存储提供商名称更改为 CASSANDRA_EXPERIMENTAL 的提交：6fd5777

Answer 2

你能删除 hibernate-ogm-mongodb 和 hibernate-ogm-cassandra 依赖的版本吗，你将从 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 指定了 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 JJ 服务器（如 WildFly）上？

hibernate-ogm - 'cassandra_experimental' 不是有效的数据存储提供程序短名称

hibernate-ogm - 'cassandra_experimental' is no valid datastore provider short name

java

cassandra
