我在我的春季專案中使用 Hibernate。但它不適用于一對一的關系。它給了我以下錯誤。
Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not determine type for: com.example.TransfertNational.model.Client, at table: ComptePaiement, for columns: [org.hibernate.mapping.Column(client)]
我在互聯網上進行了一些搜索，但它對我不起作用。

評論回復：
你可能丟失@JoinColumn的Client或ComptePaiement與mappedBy在@OneToOne注解，這取決于其將持有參考ID資料庫。
