saveAndFlush in Spring data JPA

@Entity
@Table(name = "DISC")
@NoArgsConstructor
@AllArgsConstructor
@Data
@Builder
@ToString
@EqualsAndHashCode(of = { "discId" })
public class Disc implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @ReturnInsert
    @Column(name = "DISC_ID")
    private Long discId;
..
}

and

@Repository
public interface DiscRepository extends JpaRepository<Disc, Long> {
...
}

but when I save using saveAndFlush() I have this error:

org.springframework.orm.jpa.JpaSystemException: ids for this class must be manually assigned before calling save():

Looks like you don't set the discId field, as simple as that. If you want to delegate this to the framework use @GeneratedValue (and set strategy which corresponds to your DB). The framework will handle the ids generation for you.
