如何在 Java 中提取 tar 文件？
I'm working on an application that needs to access files within a .tar. What is the easiest way to do this? I just started Java around a week ago with a C/C++ background so I'm not sure if I can implement complicated solutions.
我正在开发一个需要访问 .tar 文件的应用程序。什么是最简单的方法来做到这一点？大约一周前，我刚开始学习 Java，有 C/C++ 背景，所以我不确定我是否可以实现复杂的解决方案。
Also, can you treat .tgz files as zip entries?
另外，您可以将 .tgz 文件视为 zip 条目吗？
Thanks!

Java inclides built in function for handling bot zipped and gziped libraries. http://docs.oracle.com/javase/6/docs/api/java/util/zip/package-summary.html.
Java 包含用于处理 bot 压缩和 gzip 库的内置函数。 http://docs.oracle.com/javase/6/docs/api/java/util/zip/package-summary.html。
This can be used turn your .tgzinto a regular .tarwithout much trouble. And no you cannot treat .tgzas regular zips. They are first achived in a tar and then compressed with gzip. Even if you gunzip it, you will still need to unpack the tar archive to get any of the file out of it.
这可以用来把你.tgz变成一个普通的，.tar没有太多麻烦。不，您不能将其.tgz视为普通拉链。它们首先在 tar 中实现，然后用 gzip 压缩。即使您对它进行了 gunzip，您仍然需要解压缩 tar 存档以从中取出任何文件。

From these solutions I strongly recommend the apache commons solution : http://commons.apache.org/vfs/filesystems.html
从这些解决方案中，我强烈推荐 apache commons 解决方案：http: //commons.apache.org/vfs/filesystems.html
It will allow you to read from your tar as if it were a filesystem without doing any writes to your hard drive. You will have to know what you're looking for before you go in to it, but i doubt that will hinder you much
它将允许您从 tar 中读取，就像它是一个文件系统一样，而无需对硬盘进行任何写入。在你进入它之前你必须知道你在寻找什么，但我怀疑这会阻碍你

Tar file access can be done using TarArchiveEntryin the Apache Commons library.
可以使用Apache Commons 库中的TarArchiveEntry来访问 Tar 文件。
