解决办法：

<!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"/>

<!-- 指定所上传文件的总大小不能超过200KB。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->
<property name="maxUploadSize" value="2000"/>

<!--resolveLazily属性启用是为了推迟文件解析，以便在UploadController 中捕获文件大小异常-->
<property name="resolveLazily" value="true"/>
</bean>
