Spring 3.2：創建名爲'handlerExceptionResolver'的bean時出錯'

Question

我升級到Spring 3.2.2，但出現以下錯誤。

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

Answer 1

從spring-servlet.xml（或任何其他-servlet.xml）中刪除<mvc:annotation-driven />並重新啓動服務器。

Answer 2

我也面臨同樣的問題，當我從Spring 3.1.1升級到3.2.3版本時，Tomcat服務器拋出了相同的錯誤。我通過從servlet-context.xml文件中刪除來解決此問題。該屬性用於通過編程模型啓用Spring MVC @Controller。
