Zip bomb detected

Salut à tous,

Deux question concernant Java Excel :

1 ► Quand j'ouvre un fichier xlsx de 1.06 Mo tout va bien mais de 3.23 Mo il me dit :

Code:

---

1 2

Caused by: java.io.IOException: Zip bomb detected! The file would exceed the max. ratio of compressed file size to the size of the expanded data. This may indicate that the file is used to inflate memory usage and thus could pose a security risk. You can adjust this limit via ZipSecureFile.setMinInflateRatio() if you need to work with files which exceed this limit. Counter: 827392, cis.counter: 8192, ratio: 0.009900990099009901Limits: MIN_INFLATE_RATIO: 0.01

Même erreur avec :

Code:

1 2 3

double ratio = 0.0099900990099009901; ZipSecureFile.setMinInflateRatio(ratio);

2 ► Puis-je ouvrir un fichier xls avec un XSSF, car quand j'essaye il me dit :

Merci à tous :)

tu es sur que ton xlsx n'est pas corrompu? Poste le pour vérifier.

Pour les fichjeirs xls (aussi appelés excel 97), c'est HSSF qu'il faut utiliser.

J'aimerai pouvoir faire les deux, et je pensé que 'Qui peux le plus peux le moins' marcher aussi avec XSSF n'est-ce pas le cas ?

Voici le fichier excel :
Oups, je ne trouve pas le bouton pour insérer un fichier, et pour une image c'est 2 Mo max

Pour le fichier excel corrompu tu dois avoir raison car j'ai fais un copier coller du contenu de toutes les feuilles et là plus de problème pour le lire, donc ça doit venir du fichier source.
Pour le fichier xls comment je peux faire, car le but c'est de pouvoir ouvrir n'importe quel fichier excel, c'est quand même dommage d'avoir des restrictions sur ça ?

Les formats sont complètement différents. Les stratégies de lecture et de maintenance n'ont rien à voir entre eux et tous les deux ne supportent pas les même fonctionnalités. Tu as donc un objet spécifique au format xlsx (XSSFWorkbook) et un objet spécifique au format xls (HSSFWorkbook). Mais ça ne change pas grand chsoe au niveau de ton code au delà de la lecture, puisque les deux implémentent la même interface: Workbook.

Pour être plus concret, tu fais une classe abstraite avec l'algo en n'utilisant que les interfaces (Workbook, Row,...), et des getters abstrait pour avoir les instances. Et deux classes concrètes, une pour xlsx et une xls. Et tu instancie en fonction du fichier.

Très bien merci :)

Une classe abstraite qui implémente les interface Workbook, row...
Comme ceci ?

Ou bien ceci :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Et deux classes concrètes, une pour xlsx et une xls. Et tu instancie en fonction du fichier. */   public abstract Workbook getWorkbook();   public abstract Sheet getSheet();   public abstract Cell getCell();   public abstract Row getRow(); }

---

Ou plutôt :

Code:

---

1 2 3

public abstract HSSFWorkbook getHSSFWorkbook(); public abstract XSSFWorkbook getXSSFWorkbook();

---

Et donc, pour chaque classe Xls et Xlsx je doit faire le même code avec leurs propre instance ? N'est-ce pas un peu lourd ou redondant ?

On a dit "qui utilise" pas "qui implémente". De toutes façon c'est inutile, tu peux travailler directement avec un workbook et la factory de POI:

Code:

---

1 2 3 4 5 6 7 8

Workbook wb = WorkbookFactory.create(new File("MonFichier.xls"));   Sheet sheet1 = wb.createSheet("new sheet"); Sheet sheet2 = wb.createSheet("second sheet");   FileOutputStream fileOut = new FileOutputStream("MonFichierCopie.xls"); wb.write(fileOut); fileOut.close();

---

C'est vrai mais pour le xlsx alors, Je reste comme avant avec ces déclarations :

Code:

---

1 2 3 4 5

private XSSFWorkbook wb; private XSSFSheet sheet; private XSSFCell cell; private XSSFRow row;

---

Ou bien on peux tout faire avec :

Code:

---

1 2 3 4 5

private Workbook wb; private Sheet sheet; private Cell cell; private Row row;

---

Merci :)

tu fais tout avec les interfaces

Code:

---

1 2 3 4 5 6 7 8

Workbook wb = WorkbookFactory.create(new File("MonFichier.xlsx"));   Sheet sheet1 = wb.createSheet("new sheet"); Sheet sheet2 = wb.createSheet("second sheet");   FileOutputStream fileOut = new FileOutputStream("MonFichierCopie.xlsx"); wb.write(fileOut); fileOut.close();

---

A moins d'avoir des choses spécifiques à un format à faire, tu t'en fous que ton Workbook soit un HSSFWorkbook ou un XSSFWorkbook, que les Sheet soient des HSSFSheet ou des XSSFSheet, ...

Peux-tu regarder cette classe, j'ai enlever donc tous les XSSF :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300

java.io.FileNotFoundException: 4F.xls

Le message me semble on ne peut plus clair :weird:

Il ne peux pas ne pas le trouver car le paramètre file récupère directement le ficher par un JFileChooser

Salut,

Déjà, on peut saisir un nom de fichier inexistant dans un JFileChooser (pour la sauvegarde, et heureusement), donc un JFileChooser ne garantit pas que le fichier choisi existe.

Ensuite, forcément, quand on écrit ça :

Code:

---

1 2	wb = WorkbookFactory.create(new File(file.getName()));

---

On prend que le nom du fichier (donc sans le chemin complet) et et on recréé un fichier relatif au dossier d'exécution avec le même nom que le fichier (donc, ce n'est pas le fichier directement choisi dans le JFileChooser que tu utilises, sauf si, par hasard, le dossier d'exécution et le dossier du fichier sont les mêmes.

Pourquoi te compliques-tu la vie à chaque fois :

Code:

---

1 2	wb = WorkbookFactory.create( file );

---

Tout simplement.

C'est bon, j'ai simplement remplacer :

Code:

---

1 2	wb = WorkbookFactory.create(new File(file.getName()));

---

Par :

Code:

---

1 2	wb = WorkbookFactory.create(file);

---

Merci bien ça ma fait gagné pas mal de code :) :) :)

Sinon,

C'est quoi le but de ça :

Code:

---

1 2	fileOut = new FileOutputStream(file.getName()); wb.write(fileOut);

---

situé après le WorkbookFactory.create()(Traduction : écrire le document qu'on vient d'ouvrir dans un fichier...)

Oula ! en effet je supprimer donc ces deux lignes inutile du-coup...
