Spring 3.2:创建名为'handlerExceptionResolver‘的bean时出错

我正在升级到Spring 3.2.2，但得到了以下错误。

Answer 1

从spring-Servlet.xml(或任何其他-servlet.xml)中删除<mvc:annotation-driven />，然后重新启动服务器。

Answer 2

我也遇到了同样的问题，当我从Spring 3.1.1升级到3.2.3版本时，Tomcat服务器抛出了同样的错误。我解决了这个问题，从servlet-context.xml文件中删除。此属性用于通过编程模型启用Spring MVC @Controller。
