Minha controller

@RequestMapping("/pagamento")
@Controller
public class PagamentoController {

    @Autowired
    private CarrinhoCompras carrinho;

    @RequestMapping(value = "/finalizar", method = RequestMethod.POST)
    public ModelAndView finalizar(RedirectAttributes model) {
        System.out.println(carrinho.getTotal());

        model.addFlashAttribute("sucesso", "Pagamento Realizado com Sucesso");

        return new ModelAndView("redirect:/produtos");
    }

Oi Diego, tudo bem? Aparentemente é um detalhe na sua JSP.

Veja que no erro sua action do formulário aparece com parenteses:

<form action="${s:mvcUrl('PC#finalizar()').build()}" method="post">

Acredito que este possa ser o problema, tente novamente removendo os parenteses e avisa se funciona por favor.

<form action="${s:mvcUrl('PC#finalizar').build()}" method="post">
