如何获取秒表实例？

Question

@Before("execution(* com.lentra.dms.server.interceptors..*.pre*(..))")
    public void allInterceptors(JoinPoint joinPoint)
    {
        StopWatch stopWatch = new StopWatch();
        stopWatch.start();
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
        request.setAttribute("stopwatch",stopWatch);
            }


@Around("controller() || restController() ")
    public Object saveLogAroundControllers(ProceedingJoinPoint pjp) throws Throwable {
        StopWatch stopWatch = null;

        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
        if(request.getAttribute("stopwatch")!=null) {
            stopWatch = (StopWatch) request.getAttribute("stopwatch");
        }

        ApiLoggerDto dto = new ApiLoggerDto();
 1. loggerServiceImpl.log(dto);

       apiResponse = pjp.proceed();
    for(int i=0;i<100;i++)
    {
        logger.debug("asd");
    }
    if(stopWatch != null && stopWatch.isRunning()) {
        stopWatch.stop();
    }
    **dto.setResponseTime(stopWatch.getLastTaskTimeMillis());**

1. loggerServiceImpl.log（dto）;

   } 秒表计时有问题。在第一种方法中，我在第一种方法中创建了一个秒表实例。在第1行之前，我节省了时间，即执行for循环后95毫秒，而在第2行中保存了95毫秒。

在第1行和第2行中保存了相同的时间。

请建议我更改。
