@Embeddable + @ElementCollection (one to many) with an Enum key mapped as @MapKey fails with AnnotationException

Hibernate ORM
1

Hello,

I am having a problem mapping an @Embeddable as @ElementCollection (one to many) with an Enum as @MapKey (Hibernate 5.3.6.Final):

public enum Type
{
    TEL,
    FAX,
    MOBILE;
}

@Embeddable
public class PhoneNumber implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Basic(optional=false)
    @Column(name="contact_id", insertable=false, updatable=false)
    private Integer contactId;

    @Enumerated(EnumType.STRING)
    @Basic(optional=false)
    @Column
    private Type type = Type.MOBILE;

    @Basic(optional=false)
    @Column(name="country_dial_code")
    private Integer countryDialCode;

    @Basic(optional=false)
    @Column(name="area_code")
    private Integer areaCode;

    @Basic(optional=false)
    @Column(name="subscriber_nbr")
    private Integer subscriberNbr;

    ...
}

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

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column
    private Integer id;

    @ElementCollection
    @CollectionTable(name="PhoneNumbers", joinColumns={@JoinColumn(name="contact_id", referencedColumnName="id")})
    @MapKey(name="type")            // not @MapKeyColumn, that works!
    @MapKeyEnumerated(EnumType.STRING)
    private Map<Type, PhoneNumber> phoneNumbers;

    ...
}

This fails with:

Here’s another problem description from 2018, same result:

What’s wrong?

Looks like a bug. Since you have a replicating test case you should open a Jira issue and try to debug Hibernate to check what happens in the bindKeyFromAssociationTable method that causes this issue.

3

There’s the one here, closed + fixed:

https://hibernate.atlassian.net/browse/HHH-5393

Do you want me to open a new one?

Interesting. The bug at hand says @MapKeyColumn in the title, but it has a code example using @MapKey. The fix according to Github appears to be for @MapKeyColumn only.

5

If you can replicate it, then it’s a new bug ir maybd a use case that was not addressed by that fix you pointed out.
