JPA Hibernate, how to validate on create and ignore the validation on update

I have the following entity:

@Entity
@Table(name = "bookings")
public class Booking {


    @Null
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

    @Null
    @Column(name = "column1", columnDefinition = "VARCHAR(25) DEFAULT 'CREATED'")
    private String column1;

    //the rest of the fields....
}

It is a simple spring boot project, the rule is no column1 data should be when creating a new row(therefore it uses the value 'CREATED') however on the row update I like to change the value to 'ENDED'

Is there a way to tell Hibernate to only do the validation when you create a new row and ignore the validation when you update it?

Take a look at

@PrePersist Executed before the entity manager persist operation is actually executed or cascaded. This call is synchronous with the persist operation.

@PreUpdate Executed before the database UPDATE operation.

      @PrePersist
      protected void onCreate() {
        column1 = "CREATED";
      }

      @PreUpdate
      protected void onUpdate() {
        column1 = "ENDED";
      }

See https://docs.jboss.org/hibernate/core/4.0/hem/en-US/html/listeners.html
