Question

我在项目中使用spring data JPA和Hibernate混音。最近，我遇到了性能问题。我想在我的实体类中为二级缓存添加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).。

my spring-jpa.mxl

和我的项目xml路径

Answer 1

答案实际上在错误消息中：

在应用程序中使用二级缓存，但未给出属性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（和例如，确保二级缓存提供程序hibernate-infinispan在类路径中可用。）

您尚未配置margin-top: 1%;

所以在hibernate.cache.region.factory_class

中添加如下所示的行

persistence.xml
