=== Handling Multipart File Uploads
Spring Boot embraces the Servlet 3 `javax.servlet.http.Part` API to support uploading files. By default
Spring Boot configures Spring MVC with a maximum file of 1Mb per
file and a maximum of 10Mb of file data in a single request. You may override these values, as well as the location
to which intermediate data is stored (e.g., to the `/tmp` directory) and the threshold past which data is flushed to
disk by using the properties exposed in the `MultipartAutoConfiguration` class. If you want to specify that files be unlimited,
for example, set the `multipart.maxFileSize` property to `-1`.
The multipart support is helpful when you want to receive multipart encoded file data as a `@RequestParam`-annotated
parameter of type `MultipartFile` in a Spring MVC controller handler method.
See the {sc-spring-boot-autoconfigure}/web/MultipartAutoConfiguration.{sc-ext}[`MultipartAutoConfiguration`] source for more details.
