Java解压多重zip压缩包 -- org.apache.commons.compress.archivers.zip.ZipFile结合ZipArchiveI
Java解压多重zip压缩包-- org.apache.commons.compress.archivers.zip.ZipFile结合ZipArchiveInputStream来实现
针对前一篇文章《Java打多重zip压缩包--ByteArrayOutputStream结合org.apache.commons.compress来实现》打包后的zip文件如何解压的问题。
部分代码如下：
File f = newFile("c:/test.zip");
ZipFile zf = new ZipFile(f,"gbk");
File folder = newFile("c:/test");
if (!folder.exists()) {
folder.mkdirs();
}
for(Enumeration<ZipArchiveEntry> files = zf.getEntries();files.hasMoreElements();) {
ZipArchiveEntry zae =files.nextElement();
String zipname =zae.getName();
if(zipname.endsWith(".zip")) {
Stringinnerzip = StringUtils.removeEnd(zipname, ".zip");
Fileinnerfolder = new File(folder + File.separator + innerzip);
if(!innerfolder.exists()) {
innerfolder.mkdirs();
}
ZipArchiveInputStream zais = new ZipArchiveInputStream(zf.getInputStream(zae),"GBK", true);
FileOutputStream fos = null;
ZipArchiveEntry innerzae = null;
while((innerzae = zais.getNextZipEntry()) != null) {
fos = new FileOutputStream(folder + File.separator + innerzip +File.separator + innerzae.getName());
IOUtils.copy(zais, fos);
}
zais.close();
fos.flush();
fos.close();
} else {
ZipArchiveEntry packinfo = zf.getEntry(zipname);
Stringfilename = folder + File.separator + zipname;
FileOutputStream fos = new FileOutputStream(filename);
InputStreamis = zf.getInputStream(packinfo);
IOUtils.copy(is, fos);
is.close();
fos.flush();
fos.close();
}
}
zf.close();
解包后效果如下图：
