Java // 解压缩错误:格式错误

Question

我想递归解压缩一些存档.zip。我使用 java.util.zip 我不能使用其他库。

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);
    }
}

但是我对某些存档有一些错误：

Exception in thread "main" java.lang.IllegalArgumentException: MALFORMED
    at java.util.zip.ZipCoder.toString(ZipCoder.java:58)
    at java.util.zip.ZipFile.getZipEntry(ZipFile.java:567)
    at java.util.zip.ZipFile.access$900(ZipFile.java:61)
    at java.util.zip.ZipFile$ZipEntryIterator.next(ZipFile.java:525)
    at java.util.zip.ZipFile$ZipEntryIterator.nextElement(ZipFile.java:500)
    at java.util.zip.ZipFile$ZipEntryIterator.nextElement(ZipFile.java:481)
    at zip.ReadingArchive.unzip(ReadingArchive.java:36)
    at zip.ReadingArchive.unzip(ReadingArchive.java:82)
    at zip.ReadingArchive.unzip(ReadingArchive.java:82)
    at main.Main.main(Main.java:13)

我有这个问题，因为我的存档中有.odp。我怎么能说只使用.zip，而不使用其他文件？我该如何解决这个问题？

谢谢！

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);

在您的情况下，您需要指定另一个字符集。例如，尝试，CP437。
