我想解析一个.zip文件. .zip文件包含一个文件夹.该文件夹依次包含几个文件.我想读取所有文件而不将.zip文件写入磁盘.我有以下代码：

        zipFile = new ZipFile(file);
        Enumeration<? extends ZipEntry> entries = zipFile.entries();

        while(entries.hasMoreElements()){
            ZipEntry entry = entries.nextElement();
            InputStream stream = zipFile.getInputStream(entry);
            InputStreamReader reader = new InputStreamReader(stream, "UTF-8");
            Scanner inputStream = new Scanner(reader);
            inputStream.nextLine();

            while (inputStream.hasNext()) {
                String data = inputStream.nextLine(); // Gets a whole line
                String[] line = data.split(SEPARATOR); // Splits the line up into a string array
            }

            inputStream.close();
            stream.close();
        }
        zipFile.close();

问题在于,这仅在文件直接位于.zip文件中时有效.当文件位于.zip文件中的文件夹内时,如何调整代码,使其也起作用？

解决方法:

您可以将读取内容的代码放在if中

ZipEntry entry = entries.nextElement();
if (!entry.isDirectory()) {
    InputStream stream = zipFile.getInputStream(entry);
...
    stream.close();
}
