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

Question

我正在研究 Spring mvc 3.0 中带有注释的表单验证。当我添加<mvc:annotation-driven />时在我的 ***-servlet.xml 中，启动 eclipse 后出现以下错误:

这些是我添加的 jar :

这是我的 ***-servlet.xml

    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix">

        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

    <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，你是对的，ExceptionMethodMapping 类似乎无法在任何 spring-web 3.x(或 4.x)jar 中找到。

但是如果你看一下Spring revisions关于这个类，它似乎已于 2011 年 9 月被删除。因此，您的依赖项之一可能与您的 spring-web 依赖项“不同步”(及时地说)(奇怪的是，所有依赖项似乎都是3.1.4 中除了你的 spring-ws 之外)。我建议您将所有依赖项更新到同一版本，如果您可以选择，请从 3.1 升级到 Spring 3.2。
