使用commons压缩库创建目录的tar.gz时遇到问题。我的目录结构如下。
parent/
child/
file1.raw
fileN.raw
我正在使用以下代码进行压缩。它运行正常,无一例外。但是,当我尝试解压缩tar.gz时,得到的文件名为“ childDirToCompress”。它的大小正确,因此在打包过程中文件已清楚地彼此附加。所需的输出将是目录。我不知道我在做什么错。任何明智的公共压缩器都能使我走上正确的道路吗?
CreateTarGZ() throws CompressorException, FileNotFoundException, ArchiveException, IOException {
File f = new File("parent");
File f2 = new File("parent/childDirToCompress");
File outFile = new File(f2.getAbsolutePath() + ".tar.gz");
if(!outFile.exists()){
outFile.createNewFile();
}
FileOutputStream fos = new FileOutputStream(outFile);
TarArchiveOutputStream taos = new TarArchiveOutputStream(new GZIPOutputStream(new BufferedOutputStream(fos)));
taos.setBigNumberMode(TarArchiveOutputStream.BIGNUMBER_STAR);
taos.setLongFileMode(TarArchiveOutputStream.LONGFILE_GNU);
addFilesToCompression(taos, f2, ".");
taos.close();
}
private static void addFilesToCompression(TarArchiveOutputStream taos, File file, String dir) throws IOException{
taos.putArchiveEntry(new TarArchiveEntry(file, dir));
if (file.isFile()) {
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file));
IOUtils.copy(bis, taos);
taos.closeArchiveEntry();
bis.close();
}
else if(file.isDirectory()) {
taos.closeArchiveEntry();
for (File childFile : file.listFiles()) {
addFilesToCompression(taos, childFile, file.getName());
}
}
}
我还没有弄清楚到底出了什么问题,但是在搜寻Google缓存时我发现了一个可行的例子。对不起,风滚草!
public void CreateTarGZ()
throws FileNotFoundException, IOException
{
try {
System.out.println(new File(".").getAbsolutePath());
dirPath = "parent/childDirToCompress/";
tarGzPath = "archive.tar.gz";
fOut = new FileOutputStream(new File(tarGzPath));
bOut = new BufferedOutputStream(fOut);
gzOut = new GzipCompressorOutputStream(bOut);
tOut = new TarArchiveOutputStream(gzOut);
addFileToTarGz(tOut, dirPath, "");
} finally {
tOut.finish();
tOut.close();
gzOut.close();
bOut.close();
fOut.close();
}
}
private void addFileToTarGz(TarArchiveOutputStream tOut, String path, String base)
throws IOException
{
File f = new File(path);
System.out.println(f.exists());
String entryName = base + f.getName();
TarArchiveEntry tarEntry = new TarArchiveEntry(f, entryName);
tOut.putArchiveEntry(tarEntry);
if (f.isFile()) {
IOUtils.copy(new FileInputStream(f), tOut);
tOut.closeArchiveEntry();
} else {
tOut.closeArchiveEntry();
File[] children = f.listFiles();
if (children != null) {
for (File child : children) {
System.out.println(child.getName());
addFileToTarGz(tOut, child.getAbsolutePath(), entryName + "/");
}
}
}
}
