Hibernate：无法找到persister integracion.entidades.Bodega

晚上好人！

背景：正如我在第一个问题（两天前）中所说，我是Hibernate的新人。 在最后一个问题中，人们建议我使用Maven更好地利用依赖性。我做到了，我很高兴。

我认为我已经完成了（几乎）所有我必须做的工作来完成Hibernate项目。我遇到的问题是我不能坚持所有实体。

控制台告诉我：

这里我有树项目：

我有两个理论：

首先，问题可能是hibernate.cfg.xml导致（可能）映射类标记的路径错误。

第二，也许注释实体是错误的，因为我写错了关系（1：1,1：n，n：N）。

伙计们，你给我的所有帮助我谢谢你！

问候！
