java 在解压缩过程中获取解压的进度

Question

ZipEntry.getCompressedSize();可以获取解压缩的大小，如下面代码所示：

```java
 @SuppressWarnings("rawtypes")
    public static void unZipFiles(File zipFile, String descDir) {
        File pathFile = new File(descDir);
        if (!pathFile.exists()) {
            pathFile.mkdirs();
        }
        //解决zip文件中有中文目录或者中文文件
        try (ZipFile zip = new ZipFile(zipFile, Charset.forName("GBK"))
        ) {
            long readSize = 0L;
            long length = zipFile.length();
            for (Enumeration entries = zip.entries(); entries.hasMoreElements(); ) {
                ZipEntry entry = (ZipEntry) entries.nextElement();
                String zipEntryName = entry.getName();
                String outPath = (descDir + zipEntryName).replaceAll("\\*", "/");
                //判断路径是否存在,不存在则创建文件路径
                File file = new File(outPath.substring(0, outPath.lastIndexOf('/')));
                if (!file.exists()) {
                    file.mkdirs();
                }
                //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压
                if (new File(outPath).isDirectory()) {
                    continue;
                }
                try (
                        InputStream in = zip.getInputStream(entry);
                        //输出文件路径信息
                        OutputStream out = new FileOutputStream(outPath);
                ) {
                    byte[] buf1 = new byte[2048];
                    int len;
                    while (-1 != (len = in.read(buf1))) {
                        out.write(buf1, 0, len);
                    }
                    // 累加字节长度
                    readSize += entry.getCompressedSize();
                    log.info(readSize + "/" + length);
                }
            }
        } catch (Exception e) {
            log.error("error", e);
        }
        log.info("******************解压完毕********************");
    }

在NIO中有获取解压大小的么，Files.size(file)只能获取文件的大小，在NIO中想获取解压进度怎么做呢
    /**
     * 解压缩文件工具类
     * @param zipFile
     * @param targetPathStr
     * @throws Exception
     */
    public static void unzip(String zipFile, String targetPathStr) throws Exception {
        File pathFile = new File(targetPathStr);
        if (!pathFile.exists()) {
            pathFile.mkdirs();
        }
        final Path path = Paths.get(zipFile);
        final URI uri = URI.create("jar:" + path.toUri());
        final Map<String, String> env = new HashMap<>();
        env.put("encoding", "GBK");
        FileSystem fs = FileSystems.newFileSystem(uri, env);
        long total = Files.size(path);
        AtomicLong read =new AtomicLong();
        Files.walkFileTree(fs.getPath("/"), new SimpleFileVisitor<Path>() {
            @Override
            public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
                String name = targetPathStr + file.getName(file.getNameCount() - 1);
                Path target = Paths.get(name);
                //读取的文件大小
                log.info(read.addAndGet(Files.size(file))+"/"+total);
                Files.copy(file, target, StandardCopyOption.REPLACE_EXISTING, StandardCopyOption.COPY_ATTRIBUTES);
                return FileVisitResult.CONTINUE;
            }
        });
    }
