### 一、前言 ###

本文将基于`springboot2.3.8.RELEASE`整合`Zipkin`实现分布式链路追踪

[https://github.com/openzipkin/zipkin][https_github.com_openzipkin_zipkin]

1.  zipkin:2
2.  docker-compose version 1.29.2, build 5becea4c
3.  springboot:2.3.8.RELEASE
4.  spring-cloud-starter-zipkin:2.2.8.RELEASE

### 二、docker-compose部署Zipkin ###

git clone https://gitee.com/zhengqingya/docker-compose.git
    cd docker-compose/Liunx
    # 运行 (注：记得创建相应zipkin库和表 & 修改mysql连接配置信息，自行查看`docker-compose/Liunx/zipkin`路径下的说明)
    docker-compose -f docker-compose-zipkin.yml -p zipkin up -d

启动成功如下

### 三、SpringBoot整合Zipkin ###

#### 1、pom.xml中引入依赖 ####

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zipkin</artifactId>
        <version>2.2.8.RELEASE</version>
    </dependency>

#### 2、application.yml配置 ####

spring:
      # zipkin配置
      zipkin:
        base-url: http://127.0.0.1:9411 # TODO 服务器地址
        discovery-client-enabled: false # 关闭服务发现，否则springCloud会把zipkin的url当作服务名称
        sender.type: web                # 数据发送的方式：ACTIVEMQ RABBIT KAFKA WEB
      sleuth:
        sampler:
          probability: 1.0 # 设置抽样采集率，默认0.1（即10%），这里设置为100%-表示全部采样

#### 3、测试api ####

@Slf4j
    @RestController
    @RequestMapping("/test")
    @Api(tags = "测试api")
    public class TestController { 
    
        @GetMapping("query")
        @ApiOperation("查询数据")
        public void query() { 
            log.info("查询数据: {}", DateTime.now());
        }
    
    }

调用请求 [http://127.0.0.1/test/query][http_127.0.0.1_test_query]

查看zipkin

> 注：这里只是简单的一个测试api效果，可以集成到实际springcloud微服务项目中查看更多。
