本文介绍了一种常见的Hibernate配置错误，即使用@OneToMany或@ManyToMany注解时指向未映射的类导致的问题。通过调整@Entity注解的来源，从hibernate的包路径更改为javax的包路径，成功解决了配置异常。

配置了一个@OneToMany注解，但是项目跑起来之后一直报下面的错：

org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.project.entity.ProjectOutboundBudget.projectOutboundFeeInfos[com.eplugger.entity.ProjectOutboundFeeInfo]

从类上面看，已经为class配置了@Entity注解，怀疑的地方都查到了，但还是一无所获，直到最后偶然发现，@Entity注解用了hibernate的，而不是javax的，将其改为javax的注解，问题就解决了。

确定要放弃本次机会？
