SpringCloud(Finchley版)7 - Zipkin 服務追蹤分析

一, 簡介

Spring Cloud Sleuth 集成 zipkin 組件java

Spring Cloud Sleuth 主要功能就是在分佈式系統中提供追蹤解決方案,而且兼容支持了 zipkin,你只須要在pom文件中引入相應的依賴便可.git

二, 下載 zipkin-server :   

    https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/web

    https://gitee.com/ge.yang/spring-demo/tree/master/Jarspring

1,    啓動 zipkin-service:   java -jar zipkin-server-2.11.9-exec.jarapache

2,    啓動成功後訪問 zipkin 主頁:  http://localhost:9411/zipkin/app

三, 新建服務 service-b

1, 引入Jar包 pom.xml :maven

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.gy.cloud</groupId>
        <artifactId>cloud</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <artifactId>cloud-b</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>
    <name>cloud-b</name>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- 服務追蹤分析組件 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>
    </dependencies>

</project>

2, 配置參數 application.yml :分佈式

server:
  port: 8762

spring:
  # 當前服務名稱
  application:
    name: service-b
  # zipkin服務地址
  zipkin:
    base-url: http://localhost:9411

# 服務註冊地址
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

3, 編寫調用接口,啓動類 :spring-boot

package com.gy.cloud.cloudb;

import brave.sampler.Sampler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
@EnableEurekaClient
@SpringBootApplication
public class CloudBApplication {

    public static void main(String[] args) {
        SpringApplication.run(CloudBApplication.class, args);
        System.out.println("=== 服務B啓動成功 === ");
    }

    @Value("${server.port}")
    private String port;

    @GetMapping("/hi")
    public String home(String name) {
        name = name == null ? "SERVICE-B" : name;
        return "Hi " + name + " , I am from port: " + port;
    }

    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("/info")
    public String info(){
        System.out.println("=== SERVICE-B/info 調取 SERVICE-C/hi ===");
        return restTemplate.getForObject("http://localhost:8763/hi", String.class);
    }

    // 服務追蹤分析取樣器
    @Bean
    public Sampler defaultSampler() {
        return Sampler.ALWAYS_SAMPLE;
    }

}

啓動 service-b, 訪問: http://localhost:8762/info , 系統報錯.學習

四, 新建服務 service-c

service-c 與 service-b 基本相同, 只需稍做修改:

1, 修改配置參數 application.yml :

server:
  port: 8763

spring:
  application:
    name: service-c

2, 修改啓動類:

@GetMapping("/info")
    public String info(){
        System.out.println("=== SERVICE-B/info 調取 SERVICE-C/hi ===");
        return restTemplate.getForObject("http://localhost:8762/hi", String.class);
    }

啓動 service-c, 訪問: http://localhost:8762/info :
