Spring Boot Angular: Media Management Error

I’m encountering a 500 error when handling images and videos in my project. This is not a protection-related error, as other forms are working correctly. However, there seems to be a specific issue with media management.

To make long-term project maintenance easier, I’ve opted for a simple structure. My project uses Angular for the frontend and Spring Boot for the backend. Media files (images and videos) are all stored in Angular’s public folder, and Spring Boot loads them directly from this folder.

@Service
public class ImageService {

private final String uploadDir = "../public/images/"; // Chemin vers le répertoire public d'Angular
private final String uploadDirVideos = "../public/videos/";

public String uploadImage(MultipartFile file) throws IOException {
if (file.isEmpty()) {
throw new IllegalStateException("Cannot upload empty file.");
}

// Vérifie si le répertoire existe, sinon il le crée
Path uploadPath = Paths.get(uploadDir);
if (!Files.exists(uploadPath)) {
Files.createDirectories(uploadPath); // Crée le répertoire s'il n'existe pas
}

String originalFileName = file.getOriginalFilename();
String fileExtension = originalFileName.substring(originalFileName.lastIndexOf("."));
String newFileName = UUID.randomUUID().toString() + fileExtension;
Path filePath = uploadPath.resolve(newFileName);

Files.copy(file.getInputStream(), filePath, StandardCopyOption.REPLACE_EXISTING);

return newFileName; // Retourne le nouveau nom du fichier pour l'enregistrer dans l'entité Category
}


public String uploadVideo(MultipartFile file) throws IOException {
if (file.isEmpty()) {
throw new IllegalStateException("Cannot upload empty file.");
}

// Vérifie si le répertoire existe, sinon il le crée
Path uploadPath = Paths.get(uploadDirVideos);
if (!Files.exists(uploadPath)) {
Files.createDirectories(uploadPath); // Crée le répertoire s'il n'existe pas
}

String originalFileName = file.getOriginalFilename();
String fileExtension = originalFileName.substring(originalFileName.lastIndexOf("."));
String newFileName = UUID.randomUUID().toString() + fileExtension;
Path filePath = uploadPath.resolve(newFileName);

Files.copy(file.getInputStream(), filePath, StandardCopyOption.REPLACE_EXISTING);

return newFileName; // Retourne le nouveau nom du fichier pour l'enregistrer
}

public byte[] getImage(String fileName) throws IOException {
Path filePath = Paths.get(uploadDir + fileName);
return Files.readAllBytes(filePath);
}
public byte[] getVideo(String fileName) throws IOException {
Path filePath = Paths.get(uploadDirVideos + fileName);
return Files.readAllBytes(filePath);
}
}
