brave-http

This module contains adapters to be used with the brave-core interceptors which are tailored for http clients/servers.

  • HttpClientRequestAdapter can be used with brave-core ClientRequestInterceptor
  • HttpClientResponseAdapter can be used with brave-core ClientResponseInterceptor
  • HttpServerRequestAdapter can be used with brave-core ServerRequestInterceptor
  • HttpServerResponseAdapter can be used with brave-core ServerResponseInterceptor

These adapters take care of dealing with creating new spans and submitting required annotations and will also submit some default annotations like TraceKeys.HTTP_URL and TraceKeys.HTTP_STATUS_CODE for all requests.

To use these adapters you will have to implement HttpRequest, HttpResponse for client integrations and HttpServerRequest and HttpResponse for server integrations. These HttpRequest/HttpResponse/HttpServerRequest interfaces are adapters that let you integrate with your library of choice.

brave-resteasy-spring, brave-jaxrs2 modules are good candidates to see how the integration works and is implemented.

The Client/Server Request adapters are also configurable. You can for example choose how a span name is represented. There is an implementation called DefaultSpanNameProvider which takes the http method as span name.
