使用apache commons压缩的tar问题 [英] Tar problem with apache commons compress

问题描述

我很难用tar压缩库来压缩一些文件。

I'm having a hard time trying to tar some files using the compress library.

我的代码如下，来自commons.compress wiki exemples：

My code is the following, and is taken from the commons.compress wiki exemples :

    private static File createTarFile(String[] filePaths, String saveAs) throws Exception{

    File tarFile = new File(saveAs);
    OutputStream out = new FileOutputStream(tarFile);

    TarArchiveOutputStream aos = (TarArchiveOutputStream) new ArchiveStreamFactory().createArchiveOutputStream("tar", out);

    for(String filePath : filePaths){
        File file = new File(filePath);
        TarArchiveEntry entry = new TarArchiveEntry(file);
        entry.setSize(file.length());
        aos.putArchiveEntry(entry);
        IOUtils.copy(new FileInputStream(file), aos);
        aos.closeArchiveEntry();
    }
    aos.finish();
    out.close();


    return tarFile;
}

在此过程中没有错误，但是当我尝试解压缩文件，我得到以下：

There is no error during the process, but when I try to untar the file, I got the following :

XXXX:XXXX /home/XXXX$ tar -xf typeCommandes.tar
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

b $ b

此外，归档文件的大小比原始文件稍小，这是不正常的tar，所以有一个问题...

Also, the archive IS slighty smaller in size than the original file, which isnt normal for a tar, so there DO is a problem...

-rw-r--r--  1 XXXX nobody 12902400 Jan 14 17:11 typeCommandes.tar
-rw-r--r--  1 XXXX nobody 12901888 Jan 14 17:16 typeCommandes.csv

任何人都能告诉我我做错了什么？感谢

Anyone can tell me what I'm doing wrong ? Thanks

推荐答案

您未关闭 TarArchiveOutputStream 。在之后添加 aos.close（） aos.finish（）

You're not closing the TarArchiveOutputStream. Add aos.close() after aos.finish()
