@elek Hi, I have updated PR according to you suggestion, thank you very much. Additionally, if throw exception when execute request, the method `public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)` will not be executed, and span can not be finished, then the following jaeger span will have a error parent, just as the image shows. So I finish the old span before build a new span in `finishPreSpan`. Besides, `scope.close` also can not be ignored.

Thank you very much the idea and the patch @runzhiwang I 100% support to introduce tracing for s3g. It's a very good idea.
About the implementation: It's definitely a step forward but I started to think how is it possible to do in a transparent way without duplication. I check if the resource name is available from some generic filter and it seems to be possible.
My proposal is to do it from a central place, something like this:
```
@Provider
public class TracingFilter implements ContainerRequestFilter,
ContainerResponseFilter {
public static final String TRACING_SCOPE = "TRACING_SCOPE";
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext)
throws IOException {
Scope scope = GlobalTracer.get().buildSpan(
resourceInfo.getResourceClass().getSimpleName() + "." + resourceInfo
.getResourceMethod().getName()).startActive(true);
requestContext.setProperty(TRACING_SCOPE, scope);
}
@Override
public void filter(ContainerRequestContext requestContext,
ContainerResponseContext responseContext) throws IOException {
Object scope = requestContext.getProperty(TRACING_SCOPE);
if (scope != null) {
((Scope) scope).span().finish();
}
}
}
```
What do you think? I think it would simplify this patch (you don't need to modify all the methods...)
