Hi Shabir you are awesome I went through all the video which you shared and got better understanding earlier I was not aware of microservice and spring boot as well but after going through your video on these now have good hands on this thank you so much for making this wonderful session keep it up 🙂👍

For who wants to view/get without downloading:
@PostMapping("/upload")
public ResponseData uploadFile(@RequestParam("file") MultipartFile file) throws Exception {
Attachment attachment = null;
String downloadUrl = "";
String viewUrl = "";
attachment = attachmentService.saveAttachment(file);
downloadUrl = ServletUriComponentsBuilder.fromCurrentContextPath()
.path("/download/")
.path(attachment.getId())
.toUriString();
viewUrl = ServletUriComponentsBuilder.fromCurrentContextPath()
.path("/view/")
.path(attachment.getId())
.toUriString();

return new ResponseData(attachment.getFileName(), downloadUrl, viewUrl, file.getContentType(), file.getSize());
}

@GetMapping("/view/{fileId}")
public ResponseEntity<Resource> viewFile(@PathVariable String fileId) throws Exception {
Attachment attachment = attachmentService.getAttachment(fileId);
return ResponseEntity.ok()
.contentType(MediaType.parseMediaType(attachment.getFileType()))
.body(new ByteArrayResource(attachment.getData()));
}



And the response data add the private String viewUrl;
public class ResponseData {

private String fileName;
private String downloadUrl;
private String viewUrl;
private String fileType;
private Long fileSize;
}

there was occuring 406 error, any one can help?

Great tutorial! Thanks for this. However I have question. Ha to download several images from server? I’ve already broken my brain trying to understand how to do this, and I got nowhere

Nice video. Tips for new viewers, if you're using latest spring boot version and MySQL then change the dialect property to org.hibernate.dialect.MySQLDialect and in the Attachment class above the data field add this annotation @Column(name="data", columnDefinition = "LONGBLOB".
Then there will be no error. 😊

First of all I want to congratulate you for the brilliant work! Second, I would like to know if this demonstration of yours is valid (if it serves) for types of files that are in pdf format, mp4 (video format) etc...?

Thank you <3

when i use the download API, It says "Sorry, Photos can not open this file because the format is currently unsupported, or the file is corrupted"
Please help

Nice Video! For usual I habe problems understanding indish accent, but not here!

Man everything is okay? fine but one problem how we can delete a file in multipart file???? can you answer me?

I coded this in Kotlin and it worked fine, but when I upload a PDF, the generated URL doesn't download the PDF file. It just opens it on the web. Any thoughts?

Thank you for your video! I have a question regarding file upload. Maybe someone tries to upload a malicious file. Is there a way to scan the file before we process it? Maybe there is some kind of Java API which could be used to scan the file

what is propose of creating entity and model within different package?

Thanks for the video, it is so useful

Hey buddy a small suggestion though. We do not require so many class files just for upload and download. Everything can be done within 3 classes , A repository interface, an entity class, and a Controller. That's all. It's super simple and easy to maintain. At max we would require a DAO file. But not anymore than this

Great 👍👍👍

Great tutorial bro 🔥. Do you plain smth about „Spring boot testing Full in Depth”, will be great 🙉🚀

Great work bro..your video has been very helpful

Thank you as always nabbir, i was able to code along, and also used ServletUriComponentsBuilder.fromCurrentRequest when i was getting error with .fromContext. either way i need to study and really understand how it all works. Thanks for the video.
