  Apache POI支持读取加密的XLSX和DOCX文件 . 参考Apache POI documentation

  你的代码应该是这样的：

  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);
      }
