我刚刚开始使用 Spring 3 MVC，目前使用的是 3.2.4.RELEASE。我已经使用 spring 工具套件创建了基本项目，并添加了 Hibernate 和 mysql 的配置。这是我添加到servelet-context的代码:

<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" />
</beans:bean>

<!-- package where to search for components -->
<context:component-scan base-package="xxx.xxx.xxx" />


<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <beans:property name="dataSource" ref="dataSource"/>
    <beans:property name="packagesToScan" value="xxx.xxx.xxx"/>
    <beans:property name="hibernateProperties">
        <beans:props>
            <beans:prop key="hibernate.hbm2ddl.auto">update</beans:prop>
            <beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</beans:prop>
            <beans:prop key="hibernate.show_sql">true</beans:prop>
        </beans:props>
    </beans:property>
</beans:bean>

<!-- default data source for application -->
<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <beans:property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <beans:property name="url" value="jdbc:mysql://localhost/test"/>
    <beans:property name="username" value="user"/>
    <beans:property name="password" value="passs"/>
</beans:bean>



<!-- transaction manager -->
<beans:bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <beans:property name="sessionFactory" ref="sessionFactory"/>
</beans:bean>

这是我尝试将应用程序部署到 Tomcat 时遇到的异常。

预先感谢您的任何建议。

最佳答案

正如 Pavel Horal 评论的那样，不要同时使用 <mvc:annotation-driven />和@EnableWebMvc一起。当Spring试图处理已经增强的类而预期不会增强时，这会让Spring发疯，因此ClassCast。只需使用其中任何一个即可。
