Pourquoi jmimemagic lève une exception avec les fichiers d'extension sql?

Question

Salut Je travaille avec le framework de jeu 1.4 avec Java et j'ai une classe UnitTest qui teste une classe qui valide les fichiers avec jmimemagic mais j'ai un problème pour valider les fichiers d'extension SQL lance une exception MagicMatchNotFoundException

Pourquoi jmimemagic jette une exception les fichiers d'extension sql?

Answer 1

Jmimemagic ne supporte pas certains extensions de fichiers raison pour laquelle il lance cette exception MagicMatchNotFoundException, pour le résoudre, j'ai dû verrouiller une méthode multicatch "magic.getMagicMatch (fichier, false)" pour capturer l'exception et ajouter l'erreur dans le fichier de champ.

public static class Utils { 

    public static List<String> getFormats() { 

    String[] formats = { "pdf", "doc", "docx", "csv", "xls", "xlsx", "odt", "jpg", "png", "jpeg" }; 

    List<String> list = Arrays.asList(formats); 

    return list; 

    } 

    public static void validateFile(Validation validation, File file) { 

    if (file == null) 
     throw new IllegalArgumentException("File is null"); 

    Magic magic = new Magic(); 
    MagicMatch match; 
    try { 

     match = magic.getMagicMatch(file, false); 

     if (file.length() == 0) 
      validation.addError("file", "File is empty"); 

     if (!getFormats().contains(match.getExtension())) 
      validation.addError("file", "Format not valid"); 

    } catch (MagicParseException | MagicMatchNotFoundException | MagicException e) { 
     validation.addError("file", "Format not valid"); 
    } 

    } 
}
