Spring MVC- trzy razy wywoływana metoda z kontrolera

0

Moja metoda z kontrolera jest wywoływana trzy razy i sądzę, że jest to problem z context'em springowym oraz konfiguracją w web.xml, ale na razie nie potrafię tego naprawić. Oto kod:

Konfiguracja na moje nóbskie oko wygląda ok - ale na końcu masz jakiś problem z assetami ? spróbuj rozwiązać: - No mapping found for HTTP request with URI [/css/style.css] in DispatcherServlet with name 'dispatcher'

Co od assetów to pewnie trzeba użyć mvc:resources, ale zastanawiam się o co chodzi z tym trzykrotnym wywoływaniem metod kontrolera.

@bakeraw2 ale właściwie co za różnica? ;] Może framework sobie puszcza request do tego co wystawia jako GET w celu walidacji poprawnego deploymentu?

Wszystko na to wskazuje, ponieważ po deploy wysyłany jest trzy razy request GET a przy późniejszych requestach jest tylko raz, także problem rozwiązany ;) Dzięki

Ciekawe podejście - "dziwne ale nie tak będzie" proponuje sprawdzić dokładnie. Prosta aplikacja na springu u mnie tak się nie zachowuje przy czym ja nie mam controlera obsługującego /

Spring MVC- trzy razy wywoływana metoda z kontrolera
