@Immutable with @Entity and insertable = false and updateable = false on @Column

Question

If I use the @Immutable annotation for an object and add the updatable and insertable attributes to the insertable annotation, will it be redundant?

  @Entity
 @Immutable
 public class SomeEntity ...
 {
  @Column (name = "xyz" updatable = false, insertable = false)
  private String xyz;
  ...
 }

Answer 1

These are two methods you can use to make your entity immutable. So yes, this is redundant. I know that Hibernate (if that's what you are using) will do some optimizations for the annotated @Immutable object. I can not say for updatable=false .
