Apache Commons Compress 1.9 发布，此版本现已提供下载，在没有 GZIP 的情况下支持原始压缩流；修复了 7z 和 tar 包相关的 bug；改进了对 Java 库 XZ 的检测。
更新内容如下：
新特性
o Added support for DEFLATE streams without any gzip framing.
Issue: COMPRESS-263.
Thanks to Matthias Stevens.
Bugs 修复
o When reading 7z files unknown file properties and properties of type
kDummy are now ignored.
Issue: COMPRESS-287.
o Expanding 7z archives using LZMA compression could cause an
EOFException.
Issue: COMPRESS-286.
o Long-Name and -link or PAX-header entries in TAR archives always had
the current time as last modfication time, creating archives that
are different at the byte level each time an archive was built.
Issue: COMPRESS-289.
Thanks to Bob Robertson.
改进
o Checking for XZ for Java may be expensive. The result will now be
cached outside of an OSGi environment. You can use the new
XZUtils#setCacheXZAvailability to overrride this default behavior.
Issue: COMPRESS-285.
Commons Compress 用以实现将文件压缩或解压成 tar、zip、bzip2 等格式。
下面代码将文件压缩成zip格式：
1
2
3
4
ArArchiveEntry entry = new ArArchiveEntry(name, size);
arOutput.putArchiveEntry(entry);
arOutput.write(contentOfEntry);
arOutput.closeArchiveEntry();
Zip文件的解压缩：
1
2
3
4
5
ArArchiveEntry entry = (ArArchiveEntry) arInput.getNextEntry();
byte[] content = new byte[entry.getSize()];
LOOP UNTIL entry.getSize() HAS BEEN READ {
arInput.read(content, offset, content.length - offset);
}
