org.hibernate.AnnotationException：未知的mappedBy - Jhipster onetoone关系

Question

我在jhipster中定义的onetoone关系中遇到了这个异常：

org.hibernate.AnnotationException: Unknown mappedBy in: 
com.plan.vima.domain.Warehouse.orderItem, referenced property unknown: 
com.plan.vima.domain.OrdemItem.ordemItem

这是我添加的关系，这引起了我的问题：

 relationship OneToOne {
      OrdemItem to Warehouse {orderItem}
 }

请注意，我在运行项目时遇到了这个异常，因为在我导入了enetities和关系之后它被jhipster勒死了 - 我没有写过一行代码。

这是我完整的Jhipster项目信息：

Answer 1

我想它应该是这样的：

relationship OneToOne {
    OrdemItem(warehouse) to Warehouse {orderItem}
}

因为关系的所有者是OrdemItem。
