java - Apache Commons解压缩方法？

Question

我最近发现了 https://commons.apache.org/proper/commons-compress/zip.html ，Apache Commons Compress 库。

但是，没有直接的方法可以简单地将给定文件解压缩到特定目录。

是否有规范/简单的方法来做到这一点？

一些使用 IOUtils 的示例代码:

public static void unzip(Path path, Charset charset) throws IOException{
    String fileBaseName = FilenameUtils.getBaseName(path.getFileName().toString());
    Path destFolderPath = Paths.get(path.getParent().toString(), fileBaseName);
    
    try (ZipFile zipFile = new ZipFile(path.toFile(), ZipFile.OPEN_READ, charset)){
        Enumeration<? extends ZipEntry> entries = zipFile.entries();
        while (entries.hasMoreElements()) {
            ZipEntry entry = entries.nextElement();
            Path entryPath = destFolderPath.resolve(entry.getName());
            if (entryPath.normalize().startsWith(destFolderPath.normalize())){
                if (entry.isDirectory()) {
                    Files.createDirectories(entryPath);
                } else {
                    Files.createDirectories(entryPath.getParent());
                    try (InputStream in = zipFile.getInputStream(entry)){
                        try (OutputStream out = new FileOutputStream(entryPath.toFile())){
                            IOUtils.copy(in, out);                          
                        }
                    }
                }
            }
        }
    }
}
