Spring MVC：类路径资源中的 bean 出现 CannotLoadBeanClassException

Question

我的设置如下：

• Tomcat 7
• Spring MVC 3.0.6
• Eclipse Indigo

文件结构如下所示

src
    - main
      - java
      - resources
        - mdp-servlet.xml
        - mdp-service.xml
      - webapp
        - WEB-INF
          - web.xml
    - test

mdp-servlet.xml

    <?xml version="1.0" encoding="UTF-8"?>

     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

mdp-service.xml

    <bean id="userService" class="ch.hszt.mdp.service.UserServiceImpl" />

</beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>mdp</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>mdp</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

Sourcefolder:

• src/main/java
• src/main/resources
• src/test/ java

这是当我尝试在 eclipse 中使用 Tomcat 启动项目时收到的错误消息

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/mdp-servlet.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/mdp-servlet.xml]

有人知道解决这个问题吗？

非常感谢！
