如果是大批量最好是上传压缩包，再解压处理。
这个感觉不像是服务器的问题，像是客户端对multipart数据的封装有问题。你客户端是浏览器吗？
```xml
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding">
<value>UTF-8</value>
</property>
<property name="maxUploadSize">
<value>10485760</value><!-- 10M -->
</property>
<property name="maxInMemorySize">
<value>4096</value>
</property>
</bean>
```
用我的，我写过一个服务器上传软件，可以用，你可以看一下我的博客，上面有详细记录 我的博客 http://blog.clouded.top/index.php/2021/08/14/tkinter%e5%ae%9e%e7%8e%b0%e6%9c%8d%e5%8a%a1%e5%99%a8%e4%b8%8a%e4%bc%a0%e4%b8%8b%e8%bd%bd%e6%96%87%e4%bb%b6%e8%bd%af%e4%bb%b6/
