I have involved in microservice based system design and development using spring webflux for quite a long time. During my work period I had to build a admin portal for back office use only. Where I had to find out how to upload multipart file in spring webflux. And the best part is that, I cannot save the file to the server. So, I have to read the file content without saving it to the server. And I find out that, it is not easy.
So, I write out my thoughts as a tutorial here: https://medium.com/@eaimanshoshi/step-by-step-procedure-of-spring-webflux-multipart-file-upload-and-read-each-line-without-saving-it-6a12be64f6ee
There is also a demo project with postman collection and test file included in this tutorial.
I am sharing this here to share my learning with others. So that we can discuss about this tutorial and get benefit. Looking forward to get some feedback from you guys.
