【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）

        return new BraveServletFilter(brave.serverRequestInterceptor(),
                                      brave.serverResponseInterceptor(),
                                      new DefaultSpanNameProvider());
    }

}

说明：指定了serviceName："asyn4 - service4 - 4"

4.3、ZipkinAsyncController

package com.xxx.service4.zipkin.brave.async;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

@Api("zipkin brave async api")
@RestController
@RequestMapping("/zipkin/async/service4")
public class ZipkinAsyncController {

    @ApiOperation("trace第4步")
    @RequestMapping(value = "/test4", method = RequestMethod.GET)
    public String myboot3() {

        try {
            return "async - service4";
        } catch (Exception e) {
            e.printStackTrace();
            return "";
        }
    }

}
