O Spring esta encontrando duas classes A JetSesion e outra do vraptor!
vc está com o pacote do hibernate registrado no web.xml? se sim, tire…
Lucas deletei a anotação do web.xml.
agora aparece este erro.
A classe SessionFactoryCreator não consegui criar configuration.buildSessionFactory();

o que tem nessa linha?
dá uma olhada no método getInstance do seu AnnotationConfigurationFactory 
Mais uma duvida.
Ao chamar este metodo com as alteraç~eos que eu fiz não era pra ele inicializar o usuarioRepository certo?
Se não for pra inicializar eles esta inicializando.
public class LoginController {
private final Result result;
private final UsuarioRepository usuarioRepository;
private UsuarioLogado usuarioLogado;
private final Validator validator;
@Get("/login")
public void login() {
}
como assim não era pra inicializar?
vc não recebeu ele no construtor?
Pelo que eu entendi http://vraptor.caelum.com.br/cookbook/poupando-recursos-lazy-dependency-injection/ não era pra ele inicializar nenhum destes atributos, pois o metodo não necessita deles.
Eu fiz um teste pra analisar se toda vez UsuarioRepository esta iniciliazando. coloquei um Sysout no construtor. E ele esta iniciando toda vez que chama este metodo.
inicializar ele vai inicializar sim, já que vc recebeu eles no controller.
O que não vai inicializar é a Session do hibernate, que só vai ser criada de verdade quando alguém chamar algum método dela.
