Logging elapsed time of execution in SpringBoot rest API - spring

Question

It could be a simple solution but I am unable to get it done.
I need to log the overall execution time for my request in SpringBoot Rest API.
Request always enters to MainController always and can exit from two places-
Main Restcontroller same method or
ExceptionHandlerController handler method
I have created one custom annotation and injecting it to both main Controller and ExceptionController methods and getting elapsed time for individual methods.
So here is the problem. I need to add these individual times to calculate the total time which I don't want.
Is there any other way to log this information easily.
Aspect class:
#Aspect
#Component
public class PointsAspect {
private final static Logger logger = LoggerFactory.getLogger(PointsAspect.class);
#Around("#annotation(annotation)")
public Object logMethod(final ProceedingJoinPoint proceedingJoinPoint, final LogAround annotation)
throws Throwable {
final long start = System.currentTimeMillis();
Object obj;
try {
logger.debug("Starting...! Method Name - " +proceedingJoinPoint.getSignature().getName());
obj = proceedingJoinPoint.proceed();
} finally {
logger.debug("Exiting...! Method Name - " +proceedingJoinPoint.getSignature().getName() +"Execution Time in Milliseconds:> "+ String.valueOf(System.currentTimeMillis()-start));
}
return obj;
}
}
Marker Interface:
#Target({ElementType.METHOD})
#Retention(RetentionPolicy.RUNTIME)
public #interface LogAround {
}
And this is how I am injecting it:
**ExceptionHandlerController.java**
#LogAround
#ExceptionHandler(HttpMessageNotReadableException.class)
public GenericFailureResponse missingRequestBodyException(HttpServletResponse response,
HttpServletRequest request, Exception ex) throws IOException {
GenericFailureResponse failureResponse = new GenericFailureResponse();
//TODO: exception logic
return failureResponse;
}
**MainController.java**
#LogAround
public String getTotalPoints(#RequestParam(required=true) long memberNo,
HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
//TODO : some logic
return "something";
}

You can use a simple filter.
#Component
public class LogTimeFilter implements Filter {
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
long startTime = System.currentTimeMillis();
chain.doFilter(request, response);
long duration = System.currentTimeMillis() - startTime;
System.out.println("Request take " + duration + " ms");
}
}
