java tar压缩和解压缩

解压缩方法

//解压
public void extractTarFile(String tarFilePath, String destDirPath) throws IOException {
    File tarFile = new File(tarFilePath);
    File destDir = new File(destDirPath);
    // 创建TarArchiveInputStream
    try (TarArchiveInputStream tarInput = new TarArchiveInputStream(new FileInputStream(tarFile))) {
        TarArchiveEntry entry;
        // 逐个读取条目并解压
        while ((entry = tarInput.getNextTarEntry()) != null) {
            if (entry.isDirectory()) {
                // 如果是目录，创建相应的目录
                File directory = new File(destDir, entry.getName());
                directory.mkdirs();
            } else {
                // 如果是文件，创建相应的文件并将数据写入
                File outputFile = new File(destDir, entry.getName());
                try (BufferedOutputStream output = new BufferedOutputStream(new FileOutputStream(outputFile))) {
                    byte[] buffer = new byte[1024];
                    int bytesRead;
                    while ((bytesRead = tarInput.read(buffer)) != -1) {
                        output.write(buffer, 0, bytesRead);
                    }
                }
            }
        }
    }
