Hibernate教程示例不起作用

Question

我正在尝试按照本教程：http://howtodoinjava.com/2014/09/25/hibernate-jpa-cascade-types/

并且有一方有@OneToMany映射而另一方有@OneToOne。那可能吗 ？我收到错误

Caused by: org.hibernate.AnnotationException: Referenced property not a (One|Many)ToOne: com.springapp.mvc.entities.EmployeeEntity.accounts in mappedBy of com.springapp.mvc.entities.AccountEntity.employee

Answer 1

不可能有这个。如果一方是一对多，另一方必须是多对一。
