解决：

spring mvc中上传附件，需要做两步操作

1. 引入包commons-fileupload-*.jar，版本号可以根据项目情况调整；
2. 在spring mvc配置文件中增加配置，文件大小限制可根据项目情况调整：

   <!-- 上传文件拦截，设置最大上传文件大小   10M=10*1024*1024(B)=10485760 bytes -->  
   <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
       <property name="maxUploadSize" value="10485760" />  
   </bean>

   这样就可以实现upload上传了。
