@Traced annotation

I was wondering if it was ever discuss to have a @Traced method-level annotation?

It would allow to easily start/stop a span around a method (using AOP). We could even capture the args and return value at some point.

Something like this:

@Target({ ElementType.METHOD, ElementType.ANNOTATION_TYPE })
@Retention(RetentionPolicy.RUNTIME)
public @interface Traced {

    boolean withActiveSpanOnly() default true;

    String component() default "java-traced-annotation";
    
    String operationName() default "";

}

Apache SkyWalking offers this: https://github.com/apache/incubator-skywalking/blob/master/apm-application-toolkit/apm-toolkit-trace/src/main/java/org/apache/skywalking/apm/toolkit/trace/Trace.java

And it could be similar to the @Timed annotation from DropWizard http://metrics.dropwizard.io/3.1.0/apidocs/com/codahale/metrics/annotation/Timed.html

I am happy to review/merge if it’s not controversial.

I’m looking for the same feature. It would be nice to not mess with business logic code.
