问题描述

public static void main(String argv[]) {
    try {
        String date = new java.text.SimpleDateFormat("MM-dd-yyyy")
                .format(new java.util.Date());
        File inFolder = new File("Output/" + date + "_4D");
        File outFolder = new File("Output/" + date + "_4D" + ".zip");
        ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
                new FileOutputStream(outFolder)));
        BufferedInputStream in = null;
        byte[] data = new byte[1000];
        String files[] = inFolder.list();
        for (int i = 0; i < files.length; i++) {
            in = new BufferedInputStream(new FileInputStream(
                    inFolder.getPath() + "/" + files[i]), 1000);
            out.putNextEntry(new ZipEntry(files[i]));
            int count;
            while ((count = in.read(data, 0, 1000)) != -1) {
                out.write(data, 0, count);
            }
            out.closeEntry();
        }
        out.flush();
        out.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

推荐答案

您需要检查文件是否是目录，因为您无法将目录传递给zip方法。

You need to check if the file is a directory because you can't pass directories to the zip method.

查看此页显示如何以递归方式压缩给定目录。

Take a look at this page which shows how you can recursively zip a given directory.
