1.下载Zipkin服务端（jar包）

https://search.maven.org/remote_content?g=io.zipkin&a=zipkin-server&v=LATEST&c=exec

2.运行Zipkin服务端，看到如下提示就对了，默认将记录数据存在内存中。

zxq@ZXQdeMacBook-Air Desktop % java -jar zipkin-server-2.23.19-exec.jar

:: version 2.23.19 :: commit 0831f9b ::

2022-12-08 14:42:57.168  INFO [/] 3936 --- [oss-http-*:9411] c.l.a.s.Server                           : Serving HTTP at /0:0:0:0:0:0:0:0:9411 - http://127.0.0.1:9411/

3.在要记录调用链的服务中

    <properties>
        <spring-cloud.version>2021.0.5</spring-cloud.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>
        <!-- zipkin -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-zipkin</artifactId>
        </dependency>
    </dependencies>

   <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

yml：

spring:
  sleuth:
    sampler:
      probability: 1.0
  zipkin:
    base-url: http://127.0.0.1:9411
    sender:
      type: web

遇到个yml文件读取不到pom.xml中的变量问题，因为将mapper放在java目录下，配置了

        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        <resources>

导致读取失败，在src/main/resources下配置filtering即可

            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
