Hibernate + Spring Data JPA二级缓存XML

Question

我在我的项目中使用spring data JPA和Hibernate重新混合。 最近，我遇到了性能问题。 我想在我的实体类中为第二级缓存添加Hibernate注释@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)。 当启动tomcat时，它会抛出Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given, please either disable second level cache or set correct region factory class name to property hibernate.cache.region.factory_class (and make sure the second level cache provider, hibernate-infinispan, for example, is available in the classpath).。

和我的项目XML路径

Answer 1

答案是字面上的错误消息：

应用程序中使用了二级缓存，但未提供属性hibernate.cache.region.factory_class，请禁用二级缓存或将正确的区域工厂类名称设置为属性hibernate.cache.region.factory_class（并make确保第二级缓存提供程序hibernate-infinispan在类路径中可用）。

你没有带配置hibernate.cache.region.factory_class

这样添加一行类似下面你persistence.xml

<property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"/>
