Spring Boot File Upload and Download REST API | Spring Data JPA | JavaTechie

In this tutorial we are going to discuss about How to upload an Image into Database, and then download it back. We will be using Spring Boot, MySQL and Postman for testing out APIs.
So this tutorial will be useful If you are implementing any real-world application where you need to store the images and then send them back to the user when requested.

Hi bro , Content is very good and new. I want to say something today's many companies are storing or signing their file or photo to AWS S3, One Drive or any cloud provider and returning the URL and that URL is storing inside of these DB and these looks good and easy even If we store blob data in db it will be very huge and it will also impact the DB Performance while hitting multiple request. It's my suggestion only.

[@Javatechie]

Yes i agree with you but Already AWS S3 i covered buddy.

Every time based on previous process status we will execute next process. All are spring batch process can be start executing by invoking their Rest end point It can be implemented in java Thanks in advance
