How to Upload Multiple Images in Spring boot

They are so many developers who asked how to upload multiple images through the spring boot framework. Today I will share some code examples with you guys on how to do it more straightforwardly.

Lets Start!

my project structure;

File Upload Util Class

import java.io.IOException
import java.io.InputStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;




public class FileUploadUtil {
? ? public? static? void saveFile(String uploadDir, String fileName, MultipartFile multipartFile) throws IOException {


? ? ? ? Path uploadPath= Paths.get("C:\\Users\\User\\Downloads\\img\\img\\src\\main\\resources\\static\\"+uploadDir);
? ? ? ? if (!Files.exists(uploadPath)){
? ? ? ? ? ? Files.createDirectories(uploadPath);
? ? ? ? }
? ? ? ? try(InputStream inputStream= multipartFile.getInputStream()) {
? ? ? ? ? ? Path filePath=uploadPath.resolve(fileName);
? ? ? ? ? ? Files.copy(inputStream,filePath, StandardCopyOption.REPLACE_EXISTING);


? ? ? ? }catch (IOException ioException){


? ? ? ? }






? ? }
};        

Image Upload Controller Class

import org.springframework.web.bind.annotation.PostMapping
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;
import java.util.Arrays;
import java.util.Objects;

@RequestMapping("api/v1/img")
@RestController
public class ImageUploadController {
    @PostMapping("/upload")
    public void saveImage(@RequestParam("files")MultipartFile[] files){
       String uploadDir="profileImagesFolder";
        Arrays.asList(files).stream().forEach(file->{
            String fileName= StringUtils.cleanPath(Objects.requireNonNull(file.getOriginalFilename()));
            System.out.println(fileName);
            try {
                FileUploadUtil.saveFile(uploadDir,fileName,file);
            }catch (IOException ioException){

            }
        });

    }
}
;
