我遇到了一个奇怪的 Hibernate 异常，我无法解释。它告诉我我正在使用二级缓存，但没有在哪里hibernate.cfg.xml我是否指定二级缓存。这是例外情况：
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).

And my hibernate.cfg.xml:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

有什么想法会触发此异常吗？提前致谢！
Pau https://stackoverflow.com/users/373177/pau写在hibernate.cache.region.factory_class hibernate.cfg.xml 中必需 https://stackoverflow.com/questions/11348964/hibernate-cache-region-factory-class-required-in-hibernate-cfg-xml/11414322#11414322:
这个例外是不言自明的。你必须设置hibernate.cache.region.factory_class财产。例如，使用 ehcache 将添加以下行：
<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>
