gdy wdrożyć aplikację i mój wniosek, otrzymuję 404 na żądanie obrazu
http://localhost:8081/ --- http 200 ok
http://localhost:8081/static/img/example.jpg - http 404 not found
kiedy dodać MVC: zasoby do dyspozytora-servlet.xml
<context:annotation-config/>
<context:component-scan base-package="com.example.web"/>
<mvc:resources mapping="/static/**" location="/static/" />
i ponowna kompilacja otrzymuję 404 do/request
http://localhost:8081/ --- http 404 not foundok
http://localhost:8081/static/img/example.jpg - http 200 ok
Proszę mi pomóc dowiedzieć się, co robię źle
