public class UserValidator implements Validator {

        return User.class.equals(clazz);
    }

    public void validate(Object target, Errors errors) {
        User u = (User) target;

    }
}

@RequestMapping(value = "/makePayment", method = RequestMethod.POST)
public String saveUserInformation(@Valid User user, BindingResult result, Model model){

    CustomerPayment customerPayment = new …
