问题描述
使用java代码解tar.Z文件，程序最终跑在windows上面，不排除以后客户迁移，所以不能使用java调用系统命令的方式解压，只能通过代码来解压。java内部支持解压格式太少，后来使用apache.commons.compress解压了zip、tar.gz、 tar.bz、 tar。但是还是没有找到tar.Z怎么解压，求教高手，帮忙解答。下面是zip、tar.gz、 tar.bz、 tar几种格式的解压。 public List<String> list(InputStream inputStream, boolean isCloseStream) throws IOException { List<String> list = new ArrayList<String>(); ArchiveInputStream in = null; try { in = new ArchiveStreamFactory().createArchiveInputStream("tar", new BufferedInputStream(inputStream)); TarArchiveEntry entry = null; while ((entry = (TarArchiveEntry) in.getNextEntry()) != null) { list.addAll(FileFach.parserEveryFile(entry.getName().replaceAll("\\", "/"), in)); } } catch (ArchiveException e) { throw new ExtractorException(ErrorType.UNSUPPORTED_FILE_TYPE, e); } finally { if (isCloseStream) { IOUtils.closeQuietly(in); IOUtils.closeQuietly(inputStream); } } return list; } public List<String> list(InputStream inputStream, boolean isCloseStream) throws IOException { List<String> list = new ArrayList<String>(); ArchiveInputStream in = null; GZIPInputStream gis = null; try { gis = new GZIPInputStream(new BufferedInputStream(inputStream)); in = new ArchiveStreamFactory().createArchiveInputStream("tar", gis); TarArchiveEntry entry = null; while ((entry = (TarArchiveEntry) in.getNextEntry()) != null) { list.addAll(FileFach.parserEveryFile(entry.getName().replaceAll("\\", "/"), in)); } entry = null; } catch (ArchiveException e) { throw new ExtractorException(ErrorType.UNSUPPORTED_FILE_TYPE, e); } finally { if (isCloseStream) { IOUtils.closeQuietly(gis); IOUtils.closeQuietly(inputStream); IOUtils.closeQuietly(in); } } return list; } public List<String> list(InputStream inputStream, boolean isCloseStream) throws IOException { List<String> list = new ArrayList<String>(); ArchiveInputStream in = null; try { in = new ArchiveStreamFactory().createArchiveInputStream("tar", new BZip2CompressorInputStream(inputStream)); TarArchiveEntry entry = null; while ((entry = (TarArchiveEntry) in.getNextEntry()) != null) { list.addAll(FileFach.parserEveryFile(entry.getName().replaceAll("\\", "/"), in)); } } catch (ArchiveException e) { throw new ExtractorException(ErrorType.UNSUPPORTED_FILE_TYPE, e); } finally { if (isCloseStream) { IOUtils.closeQuietly(in); IOUtils.closeQuietly(inputStream); } } return list; } public List<String> list(InputStream inputStream, boolean isCloseStream) throws IOException { List<String> list = new ArrayList<String>(); ArchiveInputStream in = null; try { in = new ArchiveStreamFactory().createArchiveInputStream("zip", new BufferedInputStream(inputStream)); ZipArchiveEntry entry = null; while ((entry = (ZipArchiveEntry) in.getNextEntry()) != null) { list.addAll(FileFach.parserEveryFile(entry.getName().replaceAll("\\", "/"), in)); } } catch (ArchiveException e) { throw new ExtractorException(ErrorType.UNSUPPORTED_FILE_TYPE, e); } finally { if (isCloseStream) { IOUtils.closeQuietly(inputStream); IOUtils.closeQuietly(in); } } return list; }
