JAVA使用7-zip解壓縮帶密碼的Zip檔案（非Proccess方法）

首先到sourceforge網站下載下傳sevenzipjbinding壓縮包

我下載下傳的版本是sevenzipjbinding-4.65-1.04-rc-extr-only-AllWindows.zip

public void unzipDirWithPassword( final String sourceZipFile ,

            final String destinationDir , final String password ){

           RandomAccessFile randomAccessFile = null;

           ISevenZipInArchive inArchive = null;

           try{

              randomAccessFile = new RandomAccessFile(sourceZipFile, "r");

              inArchive = SevenZip.openInArchive(null, // autodetect archive type

              new RandomAccessFileInStream(randomAccessFile));

              // Getting simple interface of the archive inArchive

              ISimpleInArchive simpleInArchive = inArchive.getSimpleInterface();

              for (final ISimpleInArchiveItem item : simpleInArchive.getArchiveItems()){

                  final int[] hash = new int[] { 0 };

                  if (!item.isFolder()){

                      ExtractOperationResult result;

                      result = item.extractSlow(new ISequentialOutStream(){

                            public int write(final byte[] data) throws SevenZipException{

                                  try{

                                        if(item.getPath().indexOf(File.separator)>0){

                                            String path = destinationDir+File.separator+item.getPath(). substring(0,item.getPath().lastIndexOf(File.separator));

                                            File folderExisting = new File(path);

                                            if (!folderExisting.exists())

                                                 new File(path).mkdirs();

                                        }

                                        if(!new File(destinationDir + File.separator+item.getPath()).exists()){

                                            new File(destinationDir).createNewFile();

                                        }

                                        OutputStream out = new FileOutputStream(destinationDir+ File.separator+item.getPath());

                                        out.write(data);

                                        out.close();

                                   }catch( Exception e ){

                                        e.printStackTrace();

                                   }

                                   hash[0] |= Arrays.hashCode(data);

                                   return data.length; // Return amount of proceed data

                           }

                       },password); /// password.

                       if (result == ExtractOperationResult.OK){

                           System.out.println(String.format("%9X | %s",

                                       hash[0], item.getPath()));

                       }else{

                           System.err.println("Error extracting item: " + result);

                       }

                  }

              }

           } catch (Exception e){

                e.printStackTrace();

           } finally {

                if (inArchive != null){

                    try {

                       inArchive.close();

                    } catch (SevenZipException e){

                       System.err.println("Error closing archive: " + e);

                       e.printStackTrace();

                    }

                }

                if (randomAccessFile != null) {

                     try{

                         randomAccessFile.close();

                     } catch (IOException e){

                         System.err.println("Error closing file: " + e);

                         e.printStackTrace();

                     }

                }

}
