第二十八章 springboot + zipkin（brave定制-AsyncHttpClient）

brave本身没有对AsyncHttpClient提供类似于brave-okhttp的ClientRequestInterceptor和ClientResponseInterceptor，所以需要我们定制，而ServerRequestInterceptor和ServerResponseInterceptor是在BraveServletFilter部分直接指定就好了（这在任何client技术下都可以复用）。

实际上，ClientRequestInterceptor和ClientResponseInterceptor也是我们的定制点。

一、代码

基本参考第二十七章 springboot + zipkin（brave-okhttp实现）
