Spring Cloud 分布式应用跟踪

SpanID:阶段性ID，比如一次RPC有可能多Span

TraceID：一次RPC只有一个TraceID

整合Spring Cloud Sleuth

1.增加依赖

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-starter-sleuth
             
    

Zipkin整合

新增Zipkin服务器

增加Maven依赖

            
                
     
      io.zipkin.java
                 
     
      zipkin-server
             
            
            
                
     
      io.zipkin.java
                 
     
      zipkin-autoconfigure-ui
             
    

激活Zipkin服务器

HTTP方式采集

import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import zipkin.server.EnableZipkinServer;/** * Zipkin 服务器应用 * */@SpringBootApplication@EnableZipkinServerpublic class ZipkinServerApplication {    public static void main(String[] args) {        SpringApplication.run(ZipkinServerApplication.class, args);    }}

配置Zipkin服务器

## 应用元信息## Zipkin 服务器应用名称spring.application.name = zipkin-server## Zipkin 服务器服务端口server.port = 20000## 管理端口安全失效management.security.enabled = false

整合Zipkin客户端

改造user-service-clientHTTP方式上报增加Maven依赖

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-starter-zipkin
             
    

配置：连接zipkin服务器

## Zipkin 配置### 配置 Zipkin 服务器zipkin.server.host = localhostzipkin.server.port = 20000spring.zipkin.base-url = http://${zipkin.server.host}:${zipkin.server.port}

改造user-service-provider

增加Maven依赖

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-starter-zipkin
             
    

配置：连接zipkin服务器

## Zipkin 配置### 配置 Zipkin 服务器zipkin.server.host = localhostzipkin.server.port = 20000spring.zipkin.base-url = http://${zipkin.server.host}:${zipkin.server.port}

改造zipkin服务器：使用Stream方式订阅

增加Maven依赖

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-sleuth-zipkin-stream
             
            
            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-stream-binder-rabbit
             
    

替换激活注解:@EnableZipkinStreamServer

Stream方式采集

package com.segumentfault.spring.cloud.lesson15.zipkin.server;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.sleuth.zipkin.stream.EnableZipkinStreamServer;/** * Zipkin 服务器应用 * */@SpringBootApplication//@EnableZipkinServer@EnableZipkinStreamServerpublic class ZipkinServerApplication {    public static void main(String[] args) {        SpringApplication.run(ZipkinServerApplication.class, args);    }}

改造user-service-client

增加Maven依赖

stream方式上报

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-starter-sleuth
             
             
            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-sleuth-stream
             
            
            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-stream-binder-rabbit
             
    

注意要移除之前zipkin依赖

改造user-service-provider

增加Maven依赖

Stream方式上报

            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-starter-sleuth
             
             
            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-sleuth-stream
             
            
            
                
     
      org.springframework.cloud
                 
     
      spring-cloud-stream-binder-rabbit
             
    

注意要移除zipkin依赖
