我遇到了一个我无法解释的奇怪的休眠异常。它告诉我我正在使用二级缓存,但我没有在哪里hibernate.cfg.xml
指定二级缓存。这是一个例外:
org.hibernate.cache.NoCacheRegionFactoryAvailableException: 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).

有什么想法会触发此异常吗?提前致谢!
