本文详细介绍了在使用Hibernate框架时遇到的缓存异常问题，特别是关于NaturalIdRegion类未找到的错误。通过调整hibernate-ehcache依赖的版本，从4.3.10.Final升级到5.3.11.Final，成功解决了该问题。

1.maven 坐标依赖：是这样的时候

<dependency>
           <groupId>org.hibernate</groupId>
           <artifactId>hibernate-agroal</artifactId>
           <version>5.3.11.Final</version>
           <type>pom</type>
       </dependency>
       
       
       <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-ehcache</artifactId>
       <version>4.3.10.Final</version>
       </dependency>

控制台出现一下情况：

解决的办法：修改这个hibernate-ehcache 版本，高版本就行了；

   <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-ehcache</artifactId>
       <version>5.3.11.Final</version>
       </dependency>
