使用Apache Commons-IO，IOUtils您可以執行以下操作：
java.util.zip.ZipFile zipFile = new ZipFile(file);
try {
Enumeration extends ZipEntry> entries = zipFile.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = entries.nextElement();
File entryDestination = new File(outputDir, entry.getName());
if (entry.isDirectory()) {
entryDestination.mkdirs();
} else {
entryDestination.getParentFile().mkdirs();
InputStream in = zipFile.getInputStream(entry);
OutputStream out = new FileOutputStream(entryDestination);
IOUtils.copy(in, out);
IOUtils.closeQuietly(in);
out.close();
}
}
} finally {
zipFile.close();
}
它仍然是一些樣闆代碼，但隻有1個非奇異的依賴項：Commons-IO
