解决办法:

  1. 引入包commons-fileupload-1.3.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:
  3. <!-- 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>
