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）

public class ZipkinConfig {
@Bean
public SpanCollector spanCollector() {
HttpSpanCollector.Config spanConfig = HttpSpanCollector.Config.builder()
.compressionEnabled(false)//默认false，span在transport之前是否会被gzipped。
.connectTimeout(5000)//5s，默认10s
.flushInterval(1)//1s
.readTimeout(6000)//5s，默认60s
.build();
return HttpSpanCollector.create("http://localhost:9411",
spanConfig,

} @Bean
public Brave brave(SpanCollector spanCollector) {
Brave.Builder builder = new Brave.Builder("asyn1 - service1 - 1");//指定serviceName

说明：指定了serviceName："asyn1 - service1 - 1"
1.3、ZipkinAsyncController
package com.xxx.service1.zipkin.brave.async; import java.net.URI;
import java.util.concurrent.Future; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;

import com.ning.http.client.AsyncHttpClient;
import com.ning.http.client.Request;

import com.ning.http.client.Response; import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation; @Api("zipkin brave async api")
@RestController
@RequestMapping("/zipkin/async/service1")
public class ZipkinAsyncController { @Autowired
private AsyncHttpClient asyncHttpClient;
@Autowired
private Brave brave; @ApiOperation("trace第一步")
@RequestMapping(value = "/test1", method = RequestMethod.GET)
public String myboot() { try {
RequestBuilder builder = new RequestBuilder();
String url = "http://localhost:8032/zipkin/async/service2/test2";
builder.setUrl(url);
Request request = builder.build(); clientRequestInterceptor(request);
Future<Response> response = asyncHttpClient.executeRequest(request);
clientResponseInterceptor(response.get()); return response.get().getResponseBody();
} catch (Exception e) {
e.printStackTrace();
return "";
}
} private void clientRequestInterceptor(Request request) {
brave.clientRequestInterceptor().handle(new HttpClientRequestAdapter(new HttpClientRequest() { @Override
public URI getUri() {
return URI.create(request.getUrl());
} @Override
public String getHttpMethod() {
return request.getMethod();
} @Override
public void addHeader(String headerKey, String headerValue) {
request.getHeaders().add(headerKey, headerValue);
}
}, new DefaultSpanNameProvider()));
} private void clientResponseInterceptor(Response response) {
brave.clientResponseInterceptor().handle(new HttpClientResponseAdapter(new HttpResponse() {
public int getHttpStatusCode() {
return response.getStatusCode();
}
}));
} }
说明：
- clientRequestInterceptor(com.ning.http.client.Request request)
- 其实就是在做cs
- clientResponseInterceptor(com.ning.http.client.Response response)
- 其实就是在做cr
