Java - 解压缩文件返回 FileNotFoundException

Question

我正在尝试使用我在网上找到的方法解压缩文件。

    public static void unzipFile(String zipFile, String outputFolder) throws IOException {
        File destDir = new File(outputFolder);
        if (!destDir.exists()) {
            destDir.mkdir();
        }
        ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFile));
        ZipEntry entry = zipIn.getNextEntry();
        while (entry != null) {
            String filePath = outputFolder + File.separator + entry.getName();
            if (!entry.isDirectory()) {
                extractFile(zipIn, filePath);
            } else {
                File dir = new File(filePath);
                dir.mkdir();
            }
            zipIn.closeEntry();
            entry = zipIn.getNextEntry();
        }
        zipIn.close();
    }

    public static void extractFile(ZipInputStream zipIn, String filePath) throws IOException {
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath));
        byte[] bytesIn = new byte[4096];
        int read = 0;
        while ((read = zipIn.read(bytesIn)) != -1) {
            bos.write(bytesIn, 0, read);
        }
        bos.close();
    }

但是，我不断收到 FileNotFoundException BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath));

错误消息: java.io.FileNotFoundException:/Users/michael/NetBeansProjects/test/build/web/TEST_ZIP/my-html/css/bootstrap-theme.css(不是目录)

我尝试用以下方法更改错误行:

File file = new File(filePath);
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));

但也没有用。控制台中显示相同的错误消息。

我的 ZIP 文件结构:

my-html
|
|- css
|   |
|   |- bootstrap-theme.css
|   |- ..
|   |- ..
|
|-index.html

Answer 1

destDir.mkdir();

将其更改为:

destDir.mkdirs();

您仅创建一级目录。
