Java // unzip error :MALFORMED
提问by user2998243
I would like to unzip recursively some archive .zip. I use java.util.zip and I can't use an other library.
我想递归解压缩一些存档 .zip。我使用 java.util.zip 并且我不能使用其他库。
My code :
我的代码：
public static void unzip(String file) {
try {
File fSourceZip = new File(file);
String zipPath = file.substring(0, file.length() - 4);
File temp = new File(zipPath);
temp.mkdir();
System.out.println(zipPath + " created");
ZipFile zipFile = new ZipFile(fSourceZip);
Enumeration e = zipFile.entries();
while (e.hasMoreElements()) {
ZipEntry entry = (ZipEntry) e.nextElement();
File destinationFilePath = new File(zipPath, entry.getName());
destinationFilePath.getParentFile().mkdirs();
if (entry.isDirectory()) {
continue;
} else {
System.out.println("Extracting " + destinationFilePath);
BufferedInputStream bis = new BufferedInputStream(
zipFile.getInputStream(entry));
int b;
byte buffer[] = new byte[1024];
FileOutputStream fos = new FileOutputStream(
destinationFilePath);
BufferedOutputStream bos = new BufferedOutputStream(fos,
1024);
while ((b = bis.read(buffer, 0, 1024)) != -1) {
bos.write(buffer, 0, b);
}
bos.flush();
bos.close();
bis.close();
}
if (entry.getName().endsWith(".zip")) {
// found a zip file, try to open
unzip(destinationFilePath.getAbsolutePath());
}
}
} catch (IOException ioe) {
System.out.println("IOError :" + ioe);
}
}
But I have some error with some archive :
但是我对一些存档有一些错误：

I have this problem because there is .odp in my archive. How I can say only uses .zip, not other files ? How I can resolve this problem ?
我有这个问题，因为我的档案中有 .odp。我怎么能说只使用 .zip，而不是其他文件？我该如何解决这个问题？
Thanks !
谢谢 ！

I've just fixed it by specifying alternative (non UTF-8) charset:
我刚刚通过指定替代（非 UTF-8）字符集来修复它：
Charset CP866 = Charset.forName("CP866");
ZipFile zipFile = new ZipFile(zipArchive, CP866);
In your case, you need to specify another charset. Try, CP437, for instance.
在您的情况下，您需要指定另一个字符集。尝试，CP437例如。
