我有下面的代码做序列化和保存在文件中的输出。我还想把这个写在log4j日志文件中，正确的方法是什么？

private ByteArrayOutputStream baos = new ByteArrayOutputStream();

    public void writeToFile(){

        try (FileOutputStream fileOut = new FileOutputStream(filePath, true)) {
                 baos.writeTo(fileOut);
                 this.baos.flush();
                 log.info(baos.toByteArray())   // Is this correct will it give me the same out put as above line ?             

        }catch (IOException e) {
                    logger.error("Error while writing query: ", e);
                }
     }
