We are currently in the process of migrating our application to Spring Boot 3. We have been using the Commons FileUpload streaming API to directly load large multipart files into a remote file share. However, we have encountered an issue where the javax.servlet.http.HttpServletRequest has been migrated to jakarta.servlet.http.HttpServletRequest. As a result, the FileUpload library is no longer functioning since it requires javax.servlet.http.HttpServletRequest.
Does Servlet API or Spring framework provide a similar functionality for file streaming without the need to save all files in memory beforehand?
