Strategy generationType.identity overriding

Is It possible to change the original overriding the generationType.identity with custom one?

It’s not clear what you are asking. Try to elaborate the question with some examples.

I want to create an Identity column that stores values as string instead of Number. The column must have incremental progressive numbers but in string format. I want modifier identity strategy

@GeneratedValue(strategy = “myStrategy”)

myStrategy is is the change of strategy = GenerationType.IDENTITY

You can extend the Hibernate IdentityGenerator and return a String instead of a Number.
