code: public static void closeFileStream(InputStream inputStream, String filePath){
          try {
              if (inputStream != null) {
                  inputStream.close();
              }
          } catch (IOException e) {
              LOG.error("close file {} occur an IOExcpetion {}", filePath, e);
          }
      }
