In this project I have figured out how we can integrate distributed tracing in a Spring Boot application. We are using OpenTelemetry to export traces to Jaeger.
You can read about this on my website https://refactorfirst.com
Once you build the application using mvn clean verify, You can start the application as two service instances.
Service 1
java -jar \
target/Distributed-Service-0.0.1-SNAPSHOT.jar \
--spring.application.name=Service-1 \
--server.port=8080
Service 2
java -jar \
target/Distributed-Service-0.0.1-SNAPSHOT.jar \
--spring.application.name=Service-2 \
--server.port=8090
