Hibernate:与两个@ JoinColumn的关系的MappingException以及其中一个列的附加PK只读映射

Question

请注意以下数据库设计:

注意:不要在意这个"设计"的创造者的想法,但我不能改变它.

这是关于MobileTans和Authenticators... 之间的关系

MobileTans表的各自映射:

@Entity
@Table(name="MobileTans")
public class MobileTan implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name="ID", insertable=false, updatable=false)
    private Integer id;    // dupe read-only field, ID already in relationship below (writable)

    @Basic(optional=false)
    @Column(name="MOBILE_PHONE_NBR")
    private String mobilePhoneNbr;

    @Basic
    @Column(name="ACTIVATION_CODE")
    private String activationCode;

    @Basic
    @Column(name="ACTIVATION_ERROR")
    private Boolean activationError = Boolean.FALSE;

    @Basic
    @Column(name="STATUS")
    private Integer status;

    @OneToOne(optional=false, fetch=FetchType.EAGER)
    @JoinColumn(name="ID", referencedColumnName="ID")
    @JoinColumn(name="AUTH_NAME", referencedColumnName="AUTHENTICATOR")
    private Authenticator authenticator;

    ...
}

这里的线索是列的重复只读映射(insertable=false, updatable=false)@Id.

该ID列被定义为PK,因此在设置@Id关系时没有用处.我必须创建一个额外的列映射.我把只读只放在额外的列上,因为Hibernate(或JPA)不允许我只在关系的某些部分指定只读(我认为这是JPA规范禁止的).

编辑:身份验证实体

@Entity
@Table(name="Authenticators")
@IdClass(AuthenticatorPk.class)
public class Authenticator implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name="ID")
    private Integer id;

    @Id
    @Column(name="AUTHENTICATOR")
    private String authenticator = "";

    @Basic(optional=false)
    @Column(name="PROCEDURE")
    private String procedure;

    @Temporal(TemporalType.DATE)
    @Basic
    @Column(name="VALID_FROM")
    private Date validFrom;

    @Temporal(TemporalType.DATE)
    @Basic
    @Column(name="VALID_TO")
    private Date validTo;

    public Authenticator()
    {
    }

    ...
}

PK类:

public class AuthenticatorPk implements Serializable
{
    private static final long serialVersionUID = 1L;

    private Integer id;

    private String authenticator = "";

    public AuthenticatorPk()
    {
    }

    ...
}

启动服务器时,我从Hibernate获取映射异常:

顺便说一下,我在Wildfly 14上使用Hibernate Core 5.3.6.Final.

问题:

这有什么不对？为什么Hibernate抱怨这个？我的印象是,这是完全合法的.

其他机会是这是一个Hibernate错误......？

请注意,我更想知道这是否应该在Hibernate中工作.我对任何非JPA替代映射都不感兴趣.通过将只读的东西放到关系上,我可以得到这个,然后这可行,但不是上面描述的映射,应该......你得到它:-)
