Aplicação listavip não sobe

Estou fazendo o curso usando o sts... ja vem algumas coisas configuradas porém acho que deve ter atrapalhado algo... Fiz o index, coloquei dentro da pasta templates, configurei o controller e deu pau... no video também da pau, e o instrutor pede pra colocar a dependencia do thymeleaf, porém notei que meu projeto ja tinha estes jars nas dependencias do maven. Coloquei a dependencia no pom e não funcionou também... alguém sabe pq?

Seguem as imagens do projeto:
