Spring Boot File Upload and Download REST API Examples

In this video, I'd love to share with you how to develop REST APIs for file upload and download with Spring Boot. With the uploaded files are stored on disk; and random codes are used to identify files in download API.

Technologies:
- Spring Boot with Spring Web MVC, Spring RESTful Web Services
- Maven build

Software programs:
- Java Development Kit (OpenJDK / Oracle JDK)
- Spring Tool Suite IDE (STS)
- Postman for testing REST APIs

@20:00 I think the use of a UUID4 would have been better here. No need for Commons (though I love Commons), just use Java.

[timothystone]

On File Upload the HTTP response should be 201 Created with a Location header to the new resource.
200 OK (or Found) @13:31 is arguably not semantic.

What about pdf upload inspite of image

[xuaniennguyen]

Hi anh, em có thắc mắc muốn hỏi là trong trường hợp download.Thay vì trả về đối tượng Resource như video thì có trả về 1 mảng byte thì kết quả cũng tương tự.
Anh cho em hỏi là có sự khác nhau của việc dùng Resource và mảng byte đối với chức năng download ko ạ ?
Và em muốn hỏi thêm anh là best practice khi download file (tải được file nặng không bị tràn bộ nhớ) là gì ạ?
Cảm ơn anh !

We could've used UUID right? Does RandomString method always return unique strings?
