推荐答案

如果你想以递归方式查看zip文件中的zip文件，

If you want to look through zip files within zip files recursively,

    public void lookupSomethingInZip(InputStream fileInputStream) throws IOException {
        ZipInputStream zipInputStream = new ZipInputStream(fileInputStream);
        String entryName = "";
        ZipEntry entry = zipInputStream.getNextEntry();
        while (entry!=null) {
            entryName = entry.getName();
            if (entryName.endsWith("zip")) {
                //recur if the entry is a zip file
                lookupSomethingInZip(zipInputStream);
            }
            //do other operation with the entries..

            entry=zipInputStream.getNextEntry();
        }
    }

使用从中派生的文件输入流调用方法file -

Call the method with the file input stream derived from the file -

File file = new File(name);
lookupSomethingInZip(new FileInputStream(file));
