How are many forms handled in one controller (Spring)?

Question

Java

Imagine a situation, there is a page and it has 5 forms and it is processed by one controller. How to handle 5 forms in this controller?
Of course, we can do this, but I have doubts about the literacy of this approach!?

@RequestMapping(value = "/main", method = RequestMethod.POST)
    public String process(@ModelAttribute("one") One one, @ModelAttribute("two") Two two, @ModelAttribute("three") Three three, @ModelAttribute("Four") Four four, @ModelAttribute("Five") Five five) {
 .... Тут обрабатываем.... а чти если пришла одна форма!? пользоваться if else ?!
}

To be more precise, my question is this: How can I process a large number of forms in one controller and have a separate method for processing the form, or somehow divide the load so that it does not bridge everything into one POST request?!
