通过Java制作tar文件

问题描述

我想使用Java将文件夹压缩到tar文件（以编程方式）。我认为必须有一个开源或图书馆来做。但是，我找不到这样的方法。

I want to use Java to compress a folder to a tar file (in programmatic way). I think there must be an open source or library to do it. However, I cannot find such method.

或者，我可以制作一个zip文件并将其扩展名重命名为.tar吗？

Alternatively, could I make a zip file and rename its extended name as .tar?

一个图书馆做呢？感谢！

Anyone could suggest a library to do it? Thanks!

推荐答案

您可以使用。

取自他们的网站：

一个例子， / p>

An example, also from their site:

   // Output file stream
   FileOutputStream dest = new FileOutputStream( "c:/test/test.tar" );

   // Create a TarOutputStream
   TarOutputStream out = new TarOutputStream( new BufferedOutputStream( dest ) );

   // Files to tar
   File[] filesToTar=new File[2];
   filesToTar[0]=new File("c:/test/myfile1.txt");
   filesToTar[1]=new File("c:/test/myfile2.txt");

   for(File f:filesToTar){
      out.putNextEntry(new TarEntry(f, f.getName()));
      BufferedInputStream origin = new BufferedInputStream(new FileInputStream( f ));

      int count;
      byte data[] = new byte[2048];
      while((count = origin.read(data)) != -1) {
         out.write(data, 0, count);
      }

      out.flush();
      origin.close();
   }

   out.close();
