Class OpentracingResponseFilter

  • All Implemented Interfaces:
    EventListener, javax.servlet.Filter, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationReadyEvent>, org.springframework.context.EnvironmentAware, org.springframework.core.env.EnvironmentCapable, org.springframework.web.context.ServletContextAware
    public class OpentracingResponseFilter
extends AbstractGenericFilterBean
implements org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationReadyEvent>
    A filter that adds the trace id to the response header.

    The filter uses the configured tracer's ability to inject itself into HTTP header fields. So whatever is configured for propagating the tracer's context, is used here as well. This allows switching between, for instance Jaeger and Zipkin format.
