Podczas aktualizacji do wersji 3.2.2 wystąpił błąd.

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed

Answer 1

usunąć <mvc:annotation-driven /> od wiosny servlet.xml (lub jakiegokolwiek innego -servlet.xml) i uruchom ponownie serwer.

Answer 2

Mam również do czynienia z tym samym problemem, serwer Tomcat rzucił ten sam błąd, gdy zaktualizowałem wersję Spring 3.1.1 do wersji 3.2.3. Rozwiązałem problem, usuwając plik z plik servlet-context.xml. Ten atrybut służy do włączania Spring MVC @ Controller poprzez model programowania.
