Commons Compress文件压缩/解压缩包

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：

ArArchiveEntry entry = new ArArchiveEntry(name, size);

arOutput.putArchiveEntry(entry);

arOutput.write(contentOfEntry);

arOutput.closeArchiveEntry();

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);

}
