Let’s Develop File Upload Service From Scratch Using Java and Spring Boot
We will develop a file upload service, which will be used for image upload in our e-Commerce App using Java Spring Boot
We needed an image upload functionality for our E-Commerce App, as we need to upload images for products and categories. We will build this function as a standalone service, which can be reused later. You can use this source code for uploading and displaying images for any of your products.
First, we will build the backend in Java and Spring, then integrate it with a Web client and Android Client in other tutorials
