使用commons-compress操作zip文件
创建zip文件
public static void zip(String srcDir, String targetFile) throws IOException {
try (OutputStream fos = new FileOutputStream(targetFile);
OutputStream bos = new BufferedOutputStream(fos);
ArchiveOutputStream aos = new ZipArchiveOutputStream(bos)) {
Path dirPath = Paths.get(srcDir);
Files.walkFileTree(dirPath, new SimpleFileVisitor<Path>() {
@Override
public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs) throws IOException {
ArchiveEntry entry = new ZipArchiveEntry(dir.toFile(), dirPath.relativize(dir).toString());
aos.putArchiveEntry(entry);
aos.closeArchiveEntry();
return super.preVisitDirectory(dir, attrs);
}
@Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
ArchiveEntry entry = new ZipArchiveEntry(
file.toFile(), dirPath.relativize(file).toString());
aos.putArchiveEntry(entry);
IOUtils.copy(new FileInputStream(file.toFile()), aos);
aos.closeArchiveEntry();
return super.visitFile(file, attrs);
}
});
}
}
解压zip文件
public static void unzip(String zipFileName, String destDir) {
try (InputStream fis = Files.newInputStream(Paths.get(zipFileName));
InputStream bis = new BufferedInputStream(fis);
ArchiveInputStream ais = new ZipArchiveInputStream(bis)) {
ArchiveEntry entry;
while (Objects.nonNull(entry = ais.getNextEntry())) {
if (!ais.canReadEntryData(entry)) {
continue;
}
String name = filename(destDir, entry.getName());
File f = new File(name);
if (entry.isDirectory()) {
if (!f.isDirectory() && !f.mkdirs()) {
f.mkdirs();
}
} else {
File parent = f.getParentFile();
if (!parent.isDirectory() && !parent.mkdirs()) {
throw new IOException("failed to create directory " + parent);
}
try (OutputStream o = Files.newOutputStream(f.toPath())) {
IOUtils.copy(ais, o);
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
private static String filename(String destDir, String name) {
return destDir + File.separator + name;
}
