This is great video. The only thing is that if you pass MultipartFile list to your end point for uploading it will not scale well and eventually you will get ‘request too big’ error. If you want to upload lots of big files at once you need to use streaming. You would need to read directly from HttpServletRequest and configure I was able to transfer 30-40GB of files in this way without any problem. I haven’t tried it from Angular and insted I used Java client. However I think that your existing Angular side would still work with streaming. Once again thank you for great video and keep up the good work.

Sir, Could you guide me on how to prevent the downloaded files from disappearing when refreshing the page?

[yogeshbansal]

Hello sir,
I would like to know if my file is greater than 12 mb and at the time of downloading service returning result in blob and it is taking time on server to process and returning response how can I tell user to wait or any way to reduce the service response time?

[johnthedon]

I've exactly same code like yours but i'm getting this error `Invalid mime type "null": 'mimeType' must not be empty` ;(

[tiagovieira]

Does it cover how to upload file with other attributes? Like registering an user with a profile image...?
