二、zipkin-demo02-client8081 代码

2.1、pom.xml依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <artifactId>zipkin-demo02-client8081</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>zipkin-demo02-client8081</name>


    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

            <artifactId>spring-boot-starter</artifactId>
        </dependency>

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

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

    </dependencies>

    <!--依赖管理，用于管理spring-cloud的依赖 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2.2、application.properties

spring.zipkin.base-url=http://localhost:9411/
server.port=8081
spring.application.name=client8081

#spring.sleuth.sampler.percentage将采样比例设置为1.0，也就是全部都需要
spring.sleuth.sampler.percentage=1

2.3、Beanconfig

package com.example.zipkindemo02client8081.business.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

/**
 * @Description 请描述下该类是做什么的
 * @Author <a href="mailto:yuanlx@smartdot.com.cn">袁凌霄</a>
 * @Date 2021/9/12  16:47
 * @Verson 1.0
 **/

@Configuration
public class Beanconfig {

    @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate = new RestTemplate();
        return restTemplate;
    }
}

2.4、HelloController

package com.example.zipkindemo02client8081.business.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

/**
 * @Description 请描述下该类是做什么的
 * @Author <a href="mailto:yuanlx@smartdot.com.cn">袁凌霄</a>
 * @Date 2021/9/12  16:49
 * @Verson 1.0
 **/

@RestController
@RequestMapping("zipkin")
public class HelloController {

    public static final String url = "http://localhost:8082/zipkin/service2";

    @RequestMapping("/service1")
    public String service() throws Exception {
        System.out.println("-----调用service1-----");

        String data = restTemplate.getForObject(url, String.class);

        return "service1," + data;
    }

    @Autowired
    RestTemplate restTemplate;

}

三、zipkin-demo02-client8082 代码

pom.xml依赖 和 zipkin-demo02-client8081一样，无Beanconfign配置，其他修改如下

3.1、application.properties

spring.zipkin.base-url=http://localhost:9411/
server.port=8082
spring.application.name=client8082

#spring.sleuth.sampler.percentage将采样比例设置为1.0，也就是全部都需要
spring.sleuth.sampler.percentage=1

3.2、HelloController

package com.example.zipkindemo02client8082.business.controller;

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

/**
 * @Description 请描述下该类是做什么的
 * @Author <a href="mailto:yuanlx@smartdot.com.cn">袁凌霄</a>
 * @Date 2021/9/12  16:54
 * @Verson 1.0
 **/

@RestController
@RequestMapping("zipkin")
public class HelloController {


    @RequestMapping("/service2")
    public String service() throws Exception {
        System.out.println("-----service2-----");

        return "service2";
    }
}
