文件解压专题：支持Gzip、Rar5、rar、7z、tar.gz、zip

Gzip解压

public class GzipUploadServiceImpl implements UploadService {
   
    @Override
    public boolean isOwn(FileType fileType) {
   
        return FileType.GZ == fileType;
    }

    @Override
    public void uploadFile(String targetPath, File file, int depth, boolean isReservedDir) throws IOException, RarException {
   
        if (file.getName().endsWith(TAR_GZ)) {
   
            new TarGzUploadServiceImpl().uploadFile(targetPath, file, depth, isReservedDir);
            return;
        }
        try (InputStream is = Files.newInputStream(file.toPath());
             GzipCompressorInputStream gzip = new GzipCompressorInputStream(is)) {
   
            // 获取文件名
            String fileName = gzip.getMetaData().getFilename();
            if (fileName == null) {
   
                String name = file.getName();
                fileName = name.substring(0, name.lastIndexOf(Constants.DOT));
                fileName = fileName.substring(fileName.lastIndexOf(File.separator) + 1);
            }
            File destFile = FileUtils.getFile(targetPath, fileName);
            FileUtils.copyInputStreamToFile(gzip, destFile);
        } finally {
   
            new ProjectUtils().deleteTemFile(file);
        }
    }
}

Rar5解压

public class Rar5UploadServiceImpl implements UploadService {
   

    @Override
    public boolean isOwn(FileType fileType) {
   
        return FileType.RAR5 == fileType;
    }

    @Override
    public void uploadFile(String targetPath, File file, int count, boolean isReservedDir) throws IOException, RarException {
   
        ProjectUtils projectUtils = new ProjectUtils();
        if (count == Constants.MAX_DEPTH) {
   
            projectUtils.deleteTemFile(file);
            return;
        }

        //解压缩至指定目录outDir
        ExtractCallback.unrar5(file.getCanonicalPath(), targetPath, isReservedDir, count);

        projectUtils.deleteTemFile(file);
    }
}
