如何打開Java中使用Apache POI保護的Word/Excel的文件的密碼？ 請寫下代碼。

Answer 1

Apache POI支持讀取加密的XLSX和DOCX文件。請參閱在Apache POI documentation

你的代碼應該是這樣的：

EncryptionInfo info = new EncryptionInfo(filesystem); 
    Decryptor d = Decryptor.getInstance(info); 

    try { 
     if (!d.verifyPassword(password)) { 
      throw new RuntimeException("Unable to process: document is encrypted"); 
     } 

     InputStream dataStream = d.getDataStream(filesystem); 
     HSSFWorkbook wb = new HSSFWorkbook(dataStream); 
     // parse dataStream 

    } catch (GeneralSecurityException ex) { 
     throw new RuntimeException("Unable to process encrypted document", ex); 
    }
