我正在使用以下代码创建一个Zip文件。我想在方法createZipFromFiles中将创建的Zip作为File对象返回,以便在其他地方使用。可以通过FileOutputStream或ZipOutputStream完成吗?

public File createZipFromFiles(String zipName, List<File> files) {
    try {
        FileOutputStream fos = new FileOutputStream(zipName);
        ZipOutputStream zos = new ZipOutputStream(fos);
        for (File file : files) {
            addToZipFile(file.getName(), zos);
        }
        return null;
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;
}

public static void addToZipFile(String fileName, ZipOutputStream zos) throws FileNotFoundException, IOException {

    System.out.println("Writing '" + fileName + "' to zip file");

    File file = new File(fileName);
    FileInputStream fis = new FileInputStream(file);
    ZipEntry zipEntry = new ZipEntry(fileName);
    zos.putNextEntry(zipEntry);

    byte[] bytes = new byte[1024];
    int length;
    while ((length = fis.read(bytes)) >= 0) {
        zos.write(bytes, 0, length);
    }

    zos.closeEntry();
    fis.close();
}

答案 0 :(得分:0)

刚回来

new File(zipName);

因为您已经有了zip文件名
