hibernate - another auto generated field which is not the ID

I want to create another autogenerated field in my class.

I followed开发者_开发百科 this unanswered question - with no success

https://stackoverflow.com/questions/4930762/generate-an-auto-generated-value-of-a-field-under-java-hibernate-id-generatedv

I need even a more simple thing - I want my second field - to receive the same value as the @ID @AutoGenerated. Is there a way to do that?

As an example try like this.

@GeneratedValue(strategy = IDENTITY)
    @Column(name = "columnName", unique = true, nullable = false, insertable = false, updatable = false)
    private Integer columnName;
