Javax-Persistance : Entity does not have a primary key using Java records

Question

I am trying to create a entity class using Java record, but I get the error message "Entity does not have primary key" although I assigned an ID annotation.

    import javax.persistence.*;
    import java.time.LocalDate;

    @Entity
    public record Agent (
            @Id
            String code,
            String name,
            LocalDate date,
            String workingArea,
            String country,
            String phoneNumber,
            boolean licenseToKill,
            int credits,
            byte[] picture)
          {}

What's wrong with this?

Answer 1

A record cannot be used as Hibernate entity because it breaks the requirements of an entity according to JPA specification. Make it class and use @Immutable annotation instead:

@Entity
@Immutable
public class Agent
