Usage

julian-http-client support for OpenTracing uses interceptors. The original request is modified to include trace-related headers.

import com.github.ljtfreitas.julian.http.opentracing.TracingHTTPRequestInterceptor;
import io.opentracing.Tracer;

interface MyApi {}

Tracer tracer = // ...

TracingHTTPRequestInterceptor tracingInterceptor = new TracingHTTPRequestInterceptor(tracer);

MyApi myApi = new ProxyBuilder()
    .http()
        .interceptors()
            .add(tracingInterceptor)
        .and()
    .and()
    .build(MyApi.class, "http://my.api.com");

And that's it.
