谢谢你的帮助。
我正在尝试在Linux服务器上上传文件。当我们执行的文件少于2MB时，它会成功发生。但是当文件大小大于5MB时，会发生错误。
我也检查服务器最大帖子大小及其如下。
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" maxPostSize="10485760" />
春季应用程序filupload配置
<bean id="multipartResolver"

<property name="maxUploadSize" value="129059638" /> <!-- 20MB -->
<!-- max size of file in memory (in bytes) -->
<property name="maxInMemorySize" value="129059638" />
</bean>

最佳答案
请click here检查您的问题的多个答案。
在application.properties文件中（Spring Boot）
更改为-1而不是提供大小
如下图所示：
spring.http.multipart.max-file-size = -1
更改后如果仍然遇到相同的问题，请返回代码。
