Howto upload multiple files with Spring Boot and test it with cURL

Question

I have implemented a Controller to upload multiple files:

public class Image implements Serializable {
    private MultipartFile file;
    private Ingeger im         


        

Answer 1

I solved it using an Array instead of a Set with nested files.

Java:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void handleFileUpload(@RequestParam MultipartFile[] images, @RequestParam Integer[] numbers) {
   ...
}

cURL:

curl http://localhost:8080/upload -X POST \
-F 'files=@1.jpg;type=image/jpg' \
-F 'numbers=1' \
-F 'files=@2.jpg;type=image/jpg' \
-F 'numbers=2' \
-F 'files=@3.jpg;type=image/jpg' \
-F 'numbers=3'
