java - 无法使用 Java 为 zip64 类型提取 zip 文件

Question

我正在使用以下函数在 Java 中提取 zip 文件

public static List<String> unzipFiles(File zipFile, File targetDirectory) {
    List<String> files = new ArrayList<String>();
    BufferedOutputStream dest = null;
    FileInputStream fileInputStream = null;
    ZipInputStream zipInputStream = null;
    try {
        fileInputStream = new FileInputStream(zipFile);
        zipInputStream = new ZipInputStream(new BufferedInputStream(
                fileInputStream));
        ZipEntry zipEntry;
        int count = 0;
        while ((zipEntry = zipInputStream.getNextEntry()) != null) {
            log.debug("Extracting File Name :: " + zipEntry);
            count++;
            int length;
            byte data[] = new byte[bufferGlb];
            String fileName = zipEntry.getName();
            File opFile = new File(targetDirectory, fileName);
            FileOutputStream fileOutputStream = new FileOutputStream(opFile);
            dest = new BufferedOutputStream(fileOutputStream, bufferGlb);
            while ((length = zipInputStream.read(data, 0, bufferGlb)) != -1) {
                dest.write(data, 0, length);
            }
            dest.flush();
            files.add(fileName);
            fileOutputStream.close();
        }
        log.debug("Total " + count + " Files Unziped Successfully ");
    } catch (Exception e) {
        log.error("Error occured in unzipping the file " + zipFile, e);
}

}

这对于普通的 zip 文件完全适用。但是对于使用 zip64 格式的某些 zip 文件，我得到以下异常：

java.util.zip.ZipException: invalid entry size (expected 0 but got 21504 bytes)
at java.util.zip.ZipInputStream.readEnd(ZipInputStream.java:384)
at java.util.zip.ZipInputStream.read(ZipInputStream.java:196)

有人可以帮我解决如何提取 zip64 文件。
