I have a question: instead of directly passing a MultipartFile to the API, can I pass a DTO class containing a file (MultipartFile) and a serial number? This way, I'll be able to send multiple files with a sequence number. Consequently, when retrieving these files, I can arrange them in the specified sequence.

Hey!
I am dealing with bigger sized images ( around 10-20MB size )
What would be best method of storing it ?
Should it store in frontend side and give me the link of stored location? Or should it be handled at backend ?
What would be best practice for this case?

Hello @JavaTechie. Thanks for the great tutorial. I have question regarding test script creation for input file system where I am passing file as queryparam instead of pathparam. What would be the correct approach to test the file input(PDF file), assuming there is no repository since I am taking the input from my local path and performing internal operation on it(for example-take the file and run Post to convert PDF file to word). Kindly suggest. Thank you

Hello Sir, Thank you so much for this valuable knowledge.
I am creating apis for news app, there I will fetch all the news in one api call. but to store the image which approach should I follow I am confused.
Should I directly upload it in DB or store the URL, please guide me. Thnx once again.

How to do the same but for json post request, convert it into base 64?

[shankarraj]

Hello @JavaTechie, I am facing the whitelable error while retrieving the image with name
This application has no explicit mapping for /error, so you are seeing this as a fallback.
