Greenwich.SR2版本的Spring Cloud Zipkin实例

作者:互联网

  调用链跟踪是微服务架构中的基础能力,Spring Cloud Zipkin+Sleuth为我们提供了该能力。首先我们先建立Zipkin服务端,它需要集成Eureka,用于发现服务提供方和消费方,进行数据的采集存储、数据分析与UI展示;然后我们在服务提供方和消费方中植入Zipkin+Sleuth作为客户端,进行追踪数据的生成与上报。

  zikpin服务端(三板斧):

  1、pom里引入第三方(Twitter的)zipkin的jar包:

<?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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>zipkin</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
            <version>2.11.8</version>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.logging.log4j</groupId>
                    <artifactId>log4j-slf4j-impl</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
            <version>2.11.8</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

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


</project>

  注意标黄部分,日志jar包冲突会让zipkin无法启动的。

  2、application:

#本机端口
server.port=8899

#服务名
spring.application.name=zipkin

#注册中心地址
eureka.client.service-url.defaultZone=http://localhost:8888/eureka/

#关闭自动收集web请求
management.metrics.web.server.auto-time-requests=false

  3、主类通过@EnableZipkinServer启动zipkin:

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import zipkin2.server.internal.EnableZipkinServer;

@EnableZipkinServer
@EnableEurekaClient
@SpringBootApplication
public class ZipkinApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinApplication.class, args);
    }

}

  zipkin客户端只需在pom里引入spring-cloud-starter-zipkin即可:

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

  我们在a-bootiful-client、a-beautiful-client和a-feign-client中都引入zipkin客户端,现在打开localhost:8899点击Find Traces即可搜到它们最近1个小时的调用链:

 

   随便点一个看看:
