How to set createdAt date with jpa

I usually set the date in the @PrePersist hook:

import javax.persistence.Entity;
import javax.persistence.PrePersist;
// others ignored for brevity


@Entity
public class ComparisonReport implements Serializable {

  public static final String TABLE_NAME = "T_COMPARISON_REPORT";
  public static final String COLUMN_CREATED_AT = "CREATED_AT";

  @Column(name = COLUMN_CREATED_AT)
  private LocalDateTime createdAt;

@PrePersist
  protected void prePersist() {
    if (this.createdAt == null) createdAt = LocalDateTime.now();
  }
 //others ignored for brevity
}
