解压缩 BZIP2 档案 [英] Uncompress BZIP2 archive

问题描述

我可以解压缩 zip、gzip 和 rar 文件，但我还需要解压缩 bzip2 文件以及解压缩它们 (.tar).我还没有找到一个好的库来使用.

我使用 Java 和 Maven 非常理想，我想将它作为依赖项包含在 POM 中.

您推荐哪些图书馆?

解决方案

我能看到的最佳选择是 Apache Commons使用此 Maven 依赖项压缩.

<依赖><groupId>org.apache.commons</groupId><artifactId>commons-compress</artifactId><version>1.0</version></依赖>

来自示例:

<块引用>

FileInputStream in = new FileInputStream("archive.tar.bz2");FileOutputStream out = new FileOutputStream("archive.tar");BZip2CompressorInputStream bzIn = new BZip2CompressorInputStream(in);最终字节[]缓冲区=新字节[缓冲区大小]；整数 n = 0;while (-1 != (n = bzIn.read(buffer))) {out.write(buffer, 0, n);}关闭()；bzIn.close();

I can uncompress zip, gzip, and rar files, but I also need to uncompress bzip2 files as well as unarchive them (.tar). I haven't come across a good library to use.

I am using Java along with Maven so ideally, I'd like to include it as a dependency in the POM.

What libraries do you recommend?

解决方案

The best option I can see is Apache Commons Compress with this Maven dependency.

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-compress</artifactId>
  <version>1.0</version>
</dependency>

From the examples:

FileInputStream in = new FileInputStream("archive.tar.bz2");
FileOutputStream out = new FileOutputStream("archive.tar");
BZip2CompressorInputStream bzIn = new BZip2CompressorInputStream(in);
final byte[] buffer = new byte[buffersize];
int n = 0;
while (-1 != (n = bzIn.read(buffer))) {
  out.write(buffer, 0, n);
}
out.close();
bzIn.close();
