Thanks anyways 😀

Registration form should send some id (login email etc), that is what should be used as primary key in db, in that case any duplications will be rejected by db, that is what usually works

If I understand correctly, after 1st request there will be created new record in database, right?

Ok. So you can make "nickname" or "email" unique

And check, if user already exists

Yeah but if it is a money transaction, i know those solutions 😀

I just want to show an error when form data is sent through refresh again.

I did that using interceptor but its not working correctly when soring security is added ti project

First idea that came:
I think you can use csrf-like token for that

Per-request token
Every form on each new page will have it own unique token
