Приложение Spring Boot Ошибка выполнения DDL

0 голосов
/ 30 марта 2020

Я пытаюсь создать приложение с загрузочной пружиной, которое позволяет пользователям хранить файлы в базе данных, но у меня возникли некоторые проблемы. (исключения ниже). Надеюсь, вы, ребята, помогите мне, спасибо.

вот моя сущность: 

@Entity
@Table(name = "files")
public class DBFile {
     @Id
       @GeneratedValue(generator = "uuid")
        @GenericGenerator(name = "uuid", strategy = "uuid2")
        private String id;
    @Column(nullable = false, name = "filename")
    private String fileName;

    @Column(nullable = false, name = "filetype")

    private String fileType;
    @Column(name = "active")
    private boolean active = true;
    @Column(name = "myfile")
    @Lob
    private byte[] data;
    @Column(name = "tag")
    private String filetag;

    public DBFile() {
    }

    public DBFile( String fileName, String fileType,  byte[] data,String filetag) {

        this.fileName = fileName;
        this.fileType = fileType;
        this.data = data;
        this.filetag=filetag;
    }

//Getters and Setters..

}

Мой FileStorageService: 

@Service
public class DBFileStorageService {

    @Autowired
    private DBFileRepository dbFileRepository;

    public DBFile storeFile(MultipartFile file, String tag) {
        // Normalize file name
        String fileName = StringUtils.cleanPath(file.getOriginalFilename());
        try {
            if(fileName.contains("..")) {
                throw new FileStorageException("Sorry! Filename contains invalid path sequence " + fileName);
            }

            DBFile dbFile = new DBFile(fileName, file.getContentType(), file.getBytes(),tag);

            return dbFileRepository.save(dbFile);
        } catch (IOException ex) {
            throw new FileStorageException("Could not store file " + fileName + ". Please try again!", ex);
        }
    }

    public DBFile getFile(String fileId) {
        return dbFileRepository.findById(fileId)
                .orElseThrow(() -> new MyFileNotFoundException("File not found with id " + fileId));
    }
}

Мой файловый контроллер: 

@RestController
public class FileController {

    private static final Logger logger = LoggerFactory.getLogger(FileController.class);

    @Autowired
    private DBFileStorageService dbFileStorageService;

    @PostMapping("/uploadFile")
    public UploadFileResponse uploadFile(@RequestParam("file") MultipartFile file,String tag) {
        DBFile dbFile = dbFileStorageService.storeFile(file,tag);

        String fileDownloadUri = ServletUriComponentsBuilder.fromCurrentContextPath()
                .path("/downloadFile/")
                .path(dbFile.getId())
                .toUriString();

        return new UploadFileResponse(dbFile.getFileName(), fileDownloadUri,
                file.getContentType(), file.getSize());
    }



    @GetMapping("/downloadFile/{fileId}")
    public ResponseEntity<Resource> downloadFile(@PathVariable String fileId) {
        // Load file from database
        DBFile dbFile = dbFileStorageService.getFile(fileId);

        return ResponseEntity.ok()
                .contentType(MediaType.parseMediaType(dbFile.getFileType()))
                .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + dbFile.getFileName() + "\"")
                .body(new ByteArrayResource(dbFile.getData()));
    }

}
