I am learning spring and have a little problem. I have 3 entities to implement the same form.I follow another topic where it created a new class to handle all. I did, but I'm getting errors. Could help me?

Thank you.
@ModelAttribute as a method parameter means "Read the attribute from somewhere" but there's nowhere to read it from, so it's null.
Change your handler method to look like this:
@RequestMapping("/add")
public String userPage(Model model) {
model.addAttribute("register", new RegisterForm());
LOGGER.debug("Accessed userAdd page!");
return "index/cadastro";
}
