Spring 对于Hibernate OGM持久性设置，是否可以使用Java配置而不是persistence.xml？

到目前为止，在Hibernate OGM的所有文档中，我从未见过任何使用Spring的Java@配置的安装示例。文档和示例项目中的所有示例都使用persistence.xml来配置持久化单元

Java配置不能用于实现Hibernate OGM持久性设置有任何原因/限制吗

理想情况下，我希望将下面的persistence.xml转换为java配置：

    <!-- Use the Hibernate OGM provider: configuration will be transparent -->
    <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
    <properties>
        <!-- Here you will pick which NoSQL technology to use, and configure it;
             in this example we start a local in-memory redis_experimental node. -->
        <property name="hibernate.ogm.datastore.provider" value="redis_experimental"/>
        <property name="hibernate.ogm.datastore.host" value="127.0.0.1:6379"/>
        <property name="hibernate.cache.use_second_level_cache" value="true"/>
        <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.redis.hibernate5.SingletonRedisRegionFactory"/>
        <property name="hibernate.cache.region_prefix" value="hibernate"/>
        <property name="hibernate.cache.use_query_cache" value="true"/>
        <property name="hibernate.cache.provider_configuration_file_resource_path" value="hibernate-redis.properties"/>

    </properties>
</persistence-unit>

org.hibernate.ogm.jpa.hibernateogm持久性

多亏了本教程，我已经做到了这一点

现在，我的设置如下所示

persistence.xml（仍然需要最少的配置）

然后你只需要@Autowire

你是说Spring的

@Configuration

注释吗？事实上，我习惯称它为java配置。感谢您指出，它与配置非OGM持久化单元应该没有太大区别，请参阅

    return factory.createEntityManager();
