  • Exception in thread "main" org.hibernate.MappingException: You may only specify a cache for root

    如果出现类似下面的错误:

    
    Exception in thread "main" org.hibernate.MappingException: You may only specify a cache for root <class> mappings
        at org.hibernate.cfg.Configuration.getRootClassMapping(Configuration.java:2724)

    Process finished with exit code 1
    

    查看你设置的在配置文件设置的缓存类是否是继承着别的类,也就是说:我开始的时候是配置的是Monkey这个类…而Monkey这个类继承着Animal,因此报错了。。

    也就是说:Hibernate在二级缓存中不能配置子类
