org.beangle.commons.archiver.zip.ZipOutputStream

Reimplementation of {@link java.util.zip.ZipOutputStream java.util.zip.ZipOutputStream} that does handle the extended functionality ofthis package, especially internal/external file attributes and extra fields with different layouts for local file data and central directory entries.

This class will try to use {@link java.io.RandomAccessFile RandomAccessFile}when you know that the output is going to go to a file.

If RandomAccessFile cannot be used, this implementation will use a Data Descriptor to store size and CRC information for {@link #DEFLATED DEFLATED}entries, this means, you don't need to calculate them yourself. Unfortunately this is not possible for the {@link #STORED STORED} method, here setting theCRC and uncompressed size information is required before {@link #putNextEntry putNextEntry} can be called.


  // 文件压缩
  public static File zip(List<String> fileNames, String zipPath, String encoding) {
    try {
      FileOutputStream f = new FileOutputStream(zipPath);
      ZipOutputStream out = new ZipOutputStream(new DataOutputStream(f));
      // FIXME
      out.setEncoding(encoding);
      for (int i = 0; i < fileNames.size(); i++) {
        String fileName = fileNames.get(i);
        DataInputStream in = new DataInputStream(new FileInputStream(fileName));
        String entryName = StringUtils.substringAfterLast(fileName, File.separator);
        out.putNextEntry(new ZipEntry(entryName));
        int c;
        while ((c = in.read()) != -1) {
          out.write(c);
        }
        in.close();
      }
      out.close();
      return new File(zipPath);
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }
