Tar

io.github.pangju666.commons.compress.utils.TarUtils

方法名	返回值	用途
isTar	boolean	检查指定文件是否为有效的Tar格式
uncompress	void	解压缩TAR文件
compress	void	压缩文件/目录为TAR文件

判断是否为tar文件

根据文件内容来判断文件类型，底层基于tika实现

File file = new File("file.tar");
TarUtils.isTar(file);

byte[] bytes = FileUtils.readFileToByteArray(file);
TarUtils.isTar(bytes);

InputStream inputStream = FileUtils.openInputStream(file);
TarUtils.isTar(inputStream);

压缩

压缩单个文件或目录

File inputFile = new File("C:\logs");

File outputFile = new File("C:\output.tar");
TarUtils.compress(inputFile, outputFile);

OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
TarUtils.compress(inputFile, ouputStream);

TarArchiveOutputStream tarArchiveOutputStream = new TarArchiveOutputStream(outputStream);
TarUtils.compress(inputFile, tarArchiveOutputStream);

压缩多个文件或目录

List<File> inputFiles = Arrays.asList(new File("C:\logs"), new File("C:\logs2"));

File outputFile = new File("C:\output.tar");
TarUtils.compress(inputFiles, outputFile);

OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
TarUtils.compress(inputFiles, ouputStream);

TarArchiveOutputStream tarArchiveOutputStream = new TarArchiveOutputStream(outputStream);
TarUtils.compress(inputFiles, tarArchiveOutputStream);

解压

File outputDir = new File("C:\logs");

File inputFile = new File("C:\output.tar");
TarUtils.uncompress(inputFile, outputDir);

byte[] inputBytes = FileUtils.readFileToByteArray(inputFile);
TarUtils.uncompress(inputBytes, outputDir);

InputStream inputStream = FileUtils.openInputStream(inputFile);
TarUtils.uncompress(inputStream, outputDir);

TarFile tarFile = new TarFile(inputFile);
TarUtils.uncompress(tarFile, outputDir);

TarArchiveInputStream tarArchiveInputStream = new TarArchiveInputStream(inputFile)
TarUtils.uncompress(tarArchiveInputStream, outputDir);
