具有联接表断开列映射异常的Hibernate OneToOne映射

Question

我正在使用Spring Boot / Spring Data JPA（休眠）。我有两个实体，WorkOrder和Inspection。一个WorkOrder可以有多个Inspection，但是一个Inspection只能绑定到一个WorkOrder。当WorkOrder有一个或多个Inspection时，需要一些额外的信息，因此我也创建了一个WorkOrderInspection实体。以下是课程。通过这种配置，我得到了一个Hibernate映射异常：

  

以下字段的断开列映射：com.couplingcorp.qualitycontrol.domain.inspections.Inspection的workOrderInspection.id

我需要更改些什么来解决该错误？还是有一种更好的方法可以完全将其映射？

工作单

@Entity
@Table(name="manufacturing.workorders")
public class WorkOrder implements Serializable, Comparable<WorkOrder> {
    private int workOrderID;
    private List<WorkOrderInspection> inspections = new ArrayList<>();
    ...

    @Id
    @Column(name="pk_workorderid")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public int getWorkOrderID() {
        return workOrderID;
    }

    public void setWorkOrderID(int workOrderID) {
        this.workOrderID = workOrderID;
    }
    ...
    @OneToMany(mappedBy="workOrder",cascade=CascadeType.ALL,orphanRemoval=true)
    public List<WorkOrderInspection> getInspections() {
        return inspections;
    }

    public void setInspections(List<WorkOrderInspection> inspections) {
        this.inspections = inspections;
    }
}

检查

@Entity

    public int getInspectionID() {
        return inspectionID;
    }

    public void setInspectionID(int inspectionID) {
        this.inspectionID = inspectionID;
    }
    ...
    @OneToOne(mappedBy="inspection")
    public WorkOrderInspection getWorkOrderInspection() {
        return workOrderInspection;
    }

    public void setWorkOrderInspection(WorkOrderInspection workOrderInspection) {
