有一个类org.springframework.web.multipart.commons.CommonsMultipartResolver属于spring-web.jar，这个类也依赖于类org.apache.commons.fileupload.FileItemFactory;所以如果我导入了spring-web.jar，那么应该自动导入类org.apache.commons.fileupload.FileItemFactory所属的lib commons-fileupload。

但是现在，当我在mvc xml配置文件中追加以下代码时，我收到类org / apache / commons / fileupload / FileItemFactory的错误：

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10485760" />
    <property name="maxInMemorySize" value="4096" />
    <property name="defaultEncoding" value="UTF-8" />
</bean>

我想知道maven为什么不导入lib commons-fileupload

为什么没有自动导入类org / apache / commons / fileupload / FileItemFactory
