Best way to send file from java server to client

Question

I uploaded an image successfully in MYSQL database using spring MVC(MultipartFile) and hibernate. now I want to get it from db and set it in my page with ajax request and my request is done successfully .(server response is ok)

but the server(java) sends me the image in form of base64 URL string. So my question is :

base 64 URL is big string and so performance will be affected by it , is there any other way to send the image from server to client without encoded to BASE64 URL ?

I use Jackson library for my response . Thank you .

is there any problem sending it as MultipartFile itself ? let spring use appropriate http message converters to write to the body — Barath, Aug 04 '17 at 19:59

You can put your image into some Resource (probably ByteArrayResource containing bitmap) and then return it.

As described here: file downloading in restful web services

But I am not sure that it's more convenient way from frontend prespective.
