Class TraceWebAspect

java.lang.Object

org.springframework.cloud.sleuth.instrument.web.TraceWebAspect

public class TraceWebAspect
extends Object

Aspect that adds tracing to

• RestController annotated classes with public Callable methods
• Controller annotated classes with public Callable methods
• Controller or RestController annotated classes with public WebAsyncTask methods

For controllers an around aspect is created that wraps the Callable.call() method execution in TraceCallable

This aspect will continue a span created by the TraceFilter. It will not create a new span - since the one in TraceFilter will wait until processing has been finished

Since:

1.0.0
