Spring Boot 3.4追踪数据本地存储及Zipkin传输方式问询

问题2：使用不同传输方式发送到Zipkin #

Zipkin支持HTTP以外的多种传输协议，以下是两种常用方案：

方案1：通过Kafka发送追踪数据

1. 添加Kafka相关依赖：

implementation("io.micrometer:micrometer-tracing-bridge-otel")
implementation("io.opentelemetry:opentelemetry-exporter-kafka")
implementation("org.springframework.kafka:spring-kafka")

2. 配置应用端和Zipkin服务：

• 应用application.yaml配置：

management:
  tracing:
    sampling:
      probability: 1
otel:
  exporter:
    kafka:
      bootstrap-servers: localhost:9092
      topic: zipkin # Zipkin默认监听的Topic

• 修改Zipkin的Docker Compose配置，启用Kafka消费：

version: '2.4'
services:
  zipkin:
    image: ghcr.io/openzipkin/zipkin-slim:${TAG:-latest}
    container_name: zipkin
    environment:
      - STORAGE_TYPE=mem
      - KAFKA_BOOTSTRAP_SERVERS=kafka:9092
      - KAFKA_TOPIC=zipkin
    ports:
      - 9411:9411
  kafka:
    image: confluentinc/cp-kafka:latest
    container_name: kafka
    ports:
      - 9092:9092
    environment:
      - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092
      - KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1
      - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
  zookeeper:
    image: confluentinc/cp-zookeeper:latest
    container_name: zookeeper
    ports:
      - 2181:2181
    environment:
      - ZOOKEEPER_CLIENT_PORT=2181

方案2：通过RabbitMQ发送追踪数据

1. 添加RabbitMQ相关依赖：

implementation("io.micrometer:micrometer-tracing-bridge-otel")
implementation("io.opentelemetry:opentelemetry-exporter-rabbitmq")
implementation("org.springframework.amqp:spring-rabbit")

2. 配置应用端和Zipkin服务：

• 应用application.yaml配置：

management:
  tracing:
    sampling:
      probability: 1
otel:
  exporter:
    rabbitmq:
      host: localhost
      port: 5672
      username: guest
      password: guest
      queue: zipkin # Zipkin默认监听的队列

• 修改Zipkin的Docker Compose配置，启用RabbitMQ消费：

version: '2.4'
services:
  zipkin:
    image: ghcr.io/openzipkin/zipkin-slim:${TAG:-latest}
    container_name: zipkin
    environment:
      - STORAGE_TYPE=mem
      - RABBIT_URI=amqp://guest:guest@rabbitmq:5672
      - RABBIT_QUEUE=zipkin
    ports:
      - 9411:9411
  rabbitmq:
    image: rabbitmq:3-management
    container_name: rabbitmq
    ports:
      - 5672:5672
      - 15672:15672
