我有我的Java代碼在Netbeans的這個錯誤:org.hibernate.MappingException:外鍵(FK12A711396456CA10 :)必須有相同數量的列引用的主鍵
org.hibernate.MappingException: Foreign key (FK12A711396456CA10:devolucion_master [devolucion_consecutivo])) must have same number of columns as the referenced primary key (devolucion [detalle_ticket_id,detalle_ticket_ticket_id,detalle_ticket_fondo_fijo_id,detalle_ticket_caja_id,consecutivo]
我製作的國外從DevolucionMaster到Devolucion的關鍵,使用Devolucion的「consecutivo」和DevolucionMaster的變量「consecutivo」,問題在於Devolucion的「鍵」是複合鍵,而我只用於外鍵一個鍵的元素,可能是這就是爲什麼(它需要使用5作爲主鍵)。
這裏的DevolucionMaster.hbm.mxl:
<hibernate-mapping>

DevolucionMaster.java:(只變量,而不是set和get)
public class DevolucionMaster implements java.io.Serializable {
private DevolucionMasterId id;
private Devolucion devolucion;
private Usuario usuario;
private Ticket ticket;
private BigDecimal total;
private Date fecha;
}
Devolucion.java:(相同DevolucionMaster)
public class Devolucion implements java.io.Serializable {
private DevolucionId id;
private MotivoDevolucion motivoDevolucion;
private DetalleTicket detalleTicket;
private ControlCorte controlCorte;
private BigDecimal cantidad;
private Date fecha;
private String comentario;
private boolean controlDevolucion;
private Set devolucionMasters = new HashSet(0);
}
我不知道我的錯誤是什麼,我在互聯網上搜索了類似的錯誤,但沒有一個解決方案我讀過已經工作(原諒我的壞英語)。
非常感謝!
那麼,呃@Cebence,解決這個問題的最好方法是從'DevolucionMaster'中刪除外鍵?並把它作爲一個簡單的列'devolucion_consecutivo'? – GrayFox
但是在DB表'devolucion_master',我只檢查了外鍵'devolucion'中的'consecutivo'列作爲外鍵...如果我是對的,用你提供的解決方案,我將不得不標記或檢查其他4個元素,這些元素使我的密鑰爲'devolution'表,對吧? – GrayFox
是的,你需要在FK中有來自PK的所有列。您還可以在一張桌子上用一個例如僅使用3列FK的4列PK? (或者你的案例中有一列)。但是如果'devolucion.consecutivo'可以唯一地標識一行,那麼你不需要'devolucion' PK中的所有其他列。 – Cebence
