java - 解压缩(提取 zip)文件显示错误，存档意外结束

Question

我在这几个文件夹中有 Bookfolder(英语、印地语、日语)。将英语、印地语、日语转换为英语.zip、印地语.zip 和 japanese.zip。一切正常，我正在保存 zip 文件和 Bookfolder 中的文件夹，我正在用 java 做这件事。但是当我手动解压缩 zip 文件 ex:english.zip 时，右键单击此处的提取物，然后将错误显示为 UNEXPECTED END OF ARCHIVE。这是我的代码.

public void foldertToZip(File zipDeleteFile) {
    //System.out.println(zipDeleteFile);
    File directoryToZip = zipDeleteFile;
    List<File> fileList = new ArrayList<>();
    //System.out.println("---Getting references to all files in: " + directoryToZip.getCanonicalPath());
    getAllFiles(directoryToZip, fileList);
    //System.out.println("---Creating zip file");
    writeZipFile(directoryToZip, fileList);
    //System.out.println("---Done");
}

public static void getAllFiles(File dir, List<File> fileList) {
    try {
        File[] files = dir.listFiles();
        for (File file : files) {
            fileList.add(file);
            if (file.isDirectory()) {
                System.out.println("directory:" + file.getCanonicalPath());
                getAllFiles(file, fileList);
            } else {
                System.out.println("file:" + file.getCanonicalPath());
            }
        }
    } catch (IOException e) {
    }
}

public static void writeZipFile(File directoryToZip, List<File> fileList) {
    try {
        //try (FileOutputStream fos = new FileOutputStream(directoryToZip.getName() + ".zip"); ZipOutputStream zos = new ZipOutputStream(fos)) {
        File path = directoryToZip.getParentFile();
        File zipFile = new File(path, directoryToZip.getName() + ".zip");
        try (FileOutputStream fos = new FileOutputStream(zipFile)) {
            ZipOutputStream zos = new ZipOutputStream(fos);
            for (File file : fileList) {
                if (!file.isDirectory()) { // we only zip files, not directories
                    addToZip(directoryToZip, file,zos);
                }
            }
        }
    } catch (FileNotFoundException e) {
    } catch (IOException e) {
    }
}

public static void addToZip(File directoryToZip, File file, ZipOutputStream zos) throws FileNotFoundException,
        IOException {
    try (FileInputStream fis = new FileInputStream(file)) {
        String zipFilePath = file.getCanonicalPath().substring(directoryToZip.getCanonicalPath().length() + 1,
                file.getCanonicalPath().length());
        System.out.println("Writing '" + zipFilePath + "' to zip file");
        ZipEntry zipEntry = new ZipEntry(zipFilePath);
        zos.putNextEntry(zipEntry);
        byte[] bytes = new byte[1024];
        int length;
        while ((length = fis.read(bytes)) >= 0) {
            zos.write(bytes, 0, length);
        }
        zos.closeEntry();
    }
}`

当我提取新的 zip 文件(例如:english.zip)时，它显示错误为 archieve 的意外结束(我认为没有完全压缩)'

Answer 1

需要在writeZipFile()方法中关闭ZipOutputStream；

for (File file : fileList) {
    if (!file.isDirectory()) { // we only zip files, not directories
        addToZip(directoryToZip, file,zos);
    }
}
//here close zos
zos.close();
