[Spring Boot - Java] thymeleaf

[jabjoint]

Buonasera a tutti, stavo rivedendo SpringBoot dopo tempo.
Ho aggiunto la dipendenza di thymeleaf e quella del web.
Con il
@ResponseBody
L'app partiva regolarmente, poi in seguito all'aggiunta di thymeleaf,


Il sistema mi dice che non trova il target: "templates/index.html"
La pagina da errore:

"Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500)."


E Maven da invece questo errore:

org.thymeleaf.TemplateEngine : [THYMELEAF][http-nio-8080-exec-1] Exception processing template "index": Error resolving template [index], template might not exist or might not be accessible by any of the configured Template Resolvers
