我对 mapstruct 中的 @ManyToOne 映射有疑问。我有两张桌子

第一个：

@Entity
@Table(name = "members", schema = vsm)
public class MemberEntity{

    @Column(name = "id", nullable = false)
    protected Long id;

    @ManyToOne(optional = false)
    @JoinColumn(name = "case_id", nullable = false)
    private CaseEntity case;
}

第二个：

@Entity
@Table(name = "cases", schema = vsm)
public class CaseEntity {

    @Column(name = "id", nullable = false)
    protected Long id;

    @Column(name = "description", nullable = false)
    protected String description;
}

我有一个像这样的案例：

public class CasesDto{

    protected Long id;

    protected String description;

    private …
