问题描述
我想解压一个包含多个文件的 7zip/lzma 档案 &Java 中的目录.我尝试使用官方的 7zip SDK，但我失败了，因为我的编程技能对于这门学科来说并不那么先进.但是，我发现了一些使 Java 中的支持更容易的库，比如 LzmaOutputStream/LzmaInputStream - 但是我不知道如何使用这些流"来解压缩多文件存档.我被卡住了.
I want to decompress a 7zip/lzma archive with multiple files & directories in Java. I tried to use the official 7zip SDK, but I failed, as my programming skills are not that advanced for this subject.However I fonud some libraries which make the support in Java easier, speaking of LzmaOutputStream/LzmaInputStream - However I don't know how to use those "streams" to decompress a multi-file archive. I am stuck.
推荐答案
在示例中，将 compressed 替换为 new File("PATH_TO_FILE").示例代码将产生一个输出流，我想 LzmaOutputStream 或库具有将流转换为二进制或字符串的适当方法.
In the example, replace compressed with new File("PATH_TO_FILE"). The example code will yield an output stream, I suppose the LzmaOutputStream or the library has appropriate methods for converting the stream to binary or string.
默认情况下，Lzma 只是一种压缩算法，而不是像 tar 或 zip 这样的文件归档程序.(注:7-Zip 程序是一个文件归档器，但您链接的库不支持文件遍历和解包.
By default Lzma is only a compression algorithm, not a file archiver like tar or zip. (Note: The 7-Zip program is a file archiver, but the library you linked to does not support file traversal and unpacking.
我建议使用支持良好的压缩算法，如 Zip 或 gz.如果必须使用 lzma，则可以使用 tar 构建文件存档，然后使用 lzma 对其进行压缩.或者使用零压缩的 zip.
I would suggest using a well-supporter compression algorithm like Zip or gz. If you must use lzma you could use tar to build a file archive and then compress it with lzma. Or use zip with zero compression.
这是一个 java TAR 库.
