Spring Cloud Edgware新特性之九:Sleuth使用MQ方式整合Zipkin

衆所周知,Spring Cloud Sleuth有兩種方式整合Zipkin:

  • HTTP直連Zipkin方式
  • MQ方式,架構圖如下:

Spring Cloud Edgware及更高版本中,Sleuth使用MQ方式整合Zipkin的玩法發生了巨大改變。本文将貼出新舊版本中Sleuth如何整合Zipkin的具體操作。MQ使用的是RabbitMQ(讀者也可使用Kafka)。

Dalston及更低版本

如果您使用Spring Cloud Dalston或更低版本,那麼整合步驟如下:

伺服器端

  1. 依賴:
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-sleuth-zipkin-stream</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
    </dependency>
    <dependency>
      <groupId>io.zipkin.java</groupId>
      <artifactId>zipkin-autoconfigure-ui</artifactId>
    </dependency>
               
  2. 啟動類上添加注解

    @EnableZipkinStreamServer

  3. 配置:
    server:
      port: 9411
    spring:  
      rabbitmq:
        host: localhost
        port: 5672
        username: guest
        password: guest
               

微服務端

  1. 加依賴:
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-sleuth-stream</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
    </dependency>
               
  2. spring:
      rabbitmq:
        host: localhost
        port: 5672
        username: guest
        password: guest
               

Edgware及更高版本

對于Edgware,以上方式也可使用,但目前已标注為

廢棄

,未來将被删除!

從Edgware開始,應如下整合Zipkin——

  1. <dependency>
      <groupId>io.zipkin.java</groupId>
      <artifactId>zipkin-autoconfigure-ui</artifactId>
    </dependency>
    <dependency>
      <groupId>io.zipkin.java</groupId>
      <artifactId>zipkin-server</artifactId>
    </dependency>
    
    <!-- 使用消息的方式收集資料(使用rabbitmq) -->
    <dependency>
      <groupId>io.zipkin.java</groupId>
      <artifactId>zipkin-autoconfigure-collector-rabbitmq</artifactId>
      <version>2.3.1</version>
    </dependency>
               
  2. 啟動類上添加

    @EnableZipkinServer

  3. server:
      port: 9411
    zipkin:
      collector:
        rabbitmq:
          addresses: localhost:5672
          password: guest
          username: guest
          queue: zipkin
               

  1. <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-zipkin</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.amqp</groupId>
      <artifactId>spring-rabbit</artifactId>
    </dependency>
               
  2. spring:
      rabbitmq:
        host: localhost
        port: 5672
        username: guest
        password: guest
      zipkin:
        rabbitmq:
          queue: zipkin
               

對比及分析

對比後不難發現,從Edgware開始,Sleuth基于MQ整合Zipkin更加的簡化!不過,改動還是比較大的。官方為什麼要做這個改進呢?答案如下——

  1. Spring Cloud Edgware之前的版本使用

    Zipkin 1.x

    ,要想MQ方式收集資料,需整合

    spring-cloud-sleuth-stream

    。而在Edgware及更高版本中,使用

    Zipkin 2.x

    Zipkin 2.x

    本身已支援基于MQ的資料收集方式,故而

    spring-cloud-sleuth-stream

    将被廢棄!
  2. 兩種使用方式不相容,請讀者務必注意!
