Hibernate : Make a field Non Updatable in an Entity
Points To Remember
By default all the fields in the Hibernate Entity are updatable and insertable. To make a field non updatable in hibernate you nee to add the annotation @Column(updatable = false)Make a field Non Updatable in an Hibernate Entity
Suppose you have a User class and you want to make email as a non updatable field, all you need to do is add the @Column(updatable = false) annotation as shown in the example below.@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "email",updatable = false, nullable = false, unique = true)
private String email;
// GETTERS and SETTERS
}
Note : This only puts a hibernate level constraint, however you can still manually go and change the value of email by using db level queries.
