Bruno,

Acho que você esqueceu de chamar a classe

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

Onde esse PC é ProdutoController, ai no caso você substitui pelas iniciais da sua classe

solução!

esta com espaçamento o mapeamento do cadastraproduto

@Transactional @RequestMapping(method=RequestMethod.POST, name="cadastraProduto")
