org.hibernate.MappingException:未知实体：pack1.Persoana

我收到这个错误，我不知道我的hbm.xml文件有什么问题。 我使用EclipseMars和Hibernate5.0.2

错误：

尝试将包名放入

休眠映射中

：

<hibernate-mapping package="pack1">
    <class name="Persoana" table="PERSOANA">

并从cfg.xml中的

映射中删除类定义（
class=“Persoana”
）。
在hibernate.cfg.xml中使用
就足够了！
我发现的问题与Hibernate版本有关。我已切换到Hibernate 4.3.6决赛，效果很好！所以，不要使用Hibernate 5.0.2版
 
，class属性对我来说似乎是错误的，我需要说的是，这个问题问得不好。你应该尽可能少地编造一些东西来证明问题的存在，而不是倾吐出大量不相关的信息
