java.lang.NoClassDefFoundError：org / springframework / web / method / annotation / ExceptionMethodMapping

Question

我正在Spring MVC 3.0中研究带有批注的表单验证。 当我在Eclipse中添加<mvc:annotation-driven />到***-servlet.xml时，出现以下错误：

这些是我添加的罐子：

这是我的***-servlet.xml

    <context:component-scan base-package="com.spring3.controller" />

     <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />    

</beans>

我错过了什么？

Answer 1

做了一些研究，您是对的，在任何spring-web 3.x（或4.x）罐中似乎都找不到ExceptionMethodMapping类。

但是，如果您查看有关此类的Spring修订版 ，似乎已经在2011年9月删除了它。因此，您的依赖项之一可能与Spring-web依赖项（很奇怪）不“同步”（及时）。事实是所有这些似乎都在3.1.4中，但您的spring-ws除外）。 我建议您将所有依赖项更新为相同的版本，如果可以的话，请从3.1转到Spring 3.2。
