Hi there I have an entity
OfferItem with this two relationship manyToOne
@ManyToOne
@JoinColumn(name = "offer_id", nullable = false, insertable = false, updatable = false)
@XmlTransient
@Getter
@Setter
private Offer offer;
@ManyToOne
@JoinColumn(name = "item_id", nullable = false, insertable = false, updatable = false)
@XmlTransient
@Getter
@Setter
private Item item;
And the foreign keys configuration on the database
<addForeignKeyConstraint baseTableName="offer_item"
baseColumnNames="item_id"
constraintName="item_offer_item_fk"
referencedTableName="item"
onDelete="CASCADE" onUpdate="CASCADE"
referencedColumnNames="id"/>
<addForeignKeyConstraint baseTableName="offer_item"
baseColumnNames="offer_id"
constraintName="offers_offer_item_fk"
onDelete="CASCADE" onUpdate="CASCADE"
referencedColumnNames="id"
referencedTableName="offer"/>
the relationship with offer is bidireccional, so on the Offer entity I have this relationship with OfferItem
@OneToMany(orphanRemoval = true, cascade = {CascadeType.ALL})
@JoinColumn(name = "offer_id", nullable = false)
@XmlElementWrapper
@Getter
private List<OfferItem> offerItems = new ArrayList<>();
On Item I dont have the bidireccional relationship since is not necessary.
Now the problem is, that when I made the set of Item on OfferItem, and I add the offerItem on the OfferItems list of offer, and I save Offer. I can see how the offerItem id is generated because is persisted on cascade. But the link between the offerItem and item is lost.
I just try to set the item on OfferItem and save the entity with his own service, but nothing. I cannot persist this link between them.
Any idea or suggestion.
Regards.
Remove insertable = false, updatable = false
from join columns. Also, the mapping for offerItems
is wrong. It should be
@OneToMany(orphanRemoval = true, cascade = {CascadeType.ALL}, mappedBy = "offer")
@XmlElementWrapper
@Getter
private List<OfferItem> offerItems = new ArrayList<>();
