java - Web アプリで Thead end をインターセプトする

Question

以下のコードが与えられた場合、スレッドが終了して最後の RequestTime を 1 つだけ取得するときに、どのようにすれば resquest 時間をログに記録できますか?

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {
    new ClientRequestContextHolder();
    logger.info("request filter ("+ ClientRequestContextHolder.getContext().getAttribute("uniqueId") +") started");
    filterChain.doFilter(request, response);
    logger.info("request filter ("+ ClientRequestContextHolder.getContext().getAttribute("uniqueId") +") finished");
    long st = (long)ClientRequestContextHolder.getContext().getAttribute("request_start");
    logger.info("RequestTime: " + customFormat("###,###.###",(System.nanoTime() - st)) + "ns");

}

私の現在の出力は次のようになります
