@ModelAttributeallows you to specify the name of the model attribute. When a parameter does not have this annotation, a decapitalized class name is used as the attribute name, i.e. Person p→ "person".

If you do not specify @ModelAttributein this situation, then Spring will cause the presence of one. In this case, it will output @ModelAttribute("person"). The argument is the name of the model.

, Person , @ModelAttribute .
