@PrePersist method is not invoked when using Jakarta Data

[lordofthejars]

Hi I had a working example using Panache (the normal one with no Jakarta Data integration). Then I decided to update the example to use Jakarta Data instead of Panache. I add the dependencies and the annotation processor. Then I run the example and the @PrePersist method is not invoked so I got a constraint violation as the instant is not set.

The entity is:

package com.galaxium.holdservice.entity;

import io.quarkus.hibernate.panache.PanacheRepository;
import jakarta.persistence.*;


import java.time.Instant;

@Entity
@Table(name = "quotes")
public class Quote {

    @Id
    @Column(name = "quote_id", nullable = false, length = 50)
    public String quoteId;

    @Column(name = "flight_id", nullable = false)
    public Integer flightId;

    @Column(name = "seat_class", nullable = false, length = 50)
    public String seatClass;

    @Column(name = "quantity", nullable = false)
    public Integer quantity;

    @Column(name = "traveler_id", nullable = false)
    public Integer travelerId;

    @Column(name = "traveler_name", nullable = false, length = 255)
    public String travelerName;

    @Column(name = "price_per_seat", nullable = false)
    public Long pricePerSeat;

    @Column(name = "total_price", nullable = false)
    public Long totalPrice;

    @Column(name = "expires_at", nullable = false)
    public Instant expiresAt;

    @Enumerated(EnumType.STRING)
    @Column(name = "status", nullable = false, length = 50)
    public QuoteStatus status;

    @Column(name = "created_at", nullable = false, updatable = false)
    public Instant createdAt;

    public interface Repo extends PanacheRepository.Stateless<Quote, String> {
    }

    @PrePersist
    protected void onCreate() {
        if (createdAt == null) {
            createdAt = Instant.now();
        }
    }

    public enum QuoteStatus {
        CREATED
    }
}

Is it normal? My guess is that it should work, and I have not seen any information yet saying that this is not supported.

Using Quarkus 3.37.0

This should work, can you file an issue?

I'm not sure it should: Hibernate Data Repositories (the implementation of Jakarta Data 1.0) is backed by StatelessSessions, which expose the insert() method to "save" entities and not persist(), which does not trigger @PrePersist entity lifecycle callbacks (see https://docs.hibernate.org/orm/7.4/repositories/html_single/#programming-model). A @PostPersist method would work, but that of course has different semantics (runs after the insert is executed on the database).

Jakarta Persistence 4.0 introduces a @PreInsert lifecycle event, providing a stateless alternative, but that will be supported by Hibernate 8.0 which is currently not available in Quarkus.

Oh, OK, I see. Oops.

Oh well, you can always extend PanacheEntity.Stateless and override insert(), or similarly on the repository, as a workaround.

Ok so this is not an issue, it will be fixed later; for now I will do these operations on the business code.
