How to specify service name when using opentelemetry-spring-starter

[tinnapat]

Hi

How can I specify service name when using opentelemetry-spring-starter?

In the documents there is no properties to specify service name. I have tried setting otel.service.name in spring configuration and also by setting OTEL_SERVICE_NAME environment variables, but the service name shown always be unknown_service:java

Thank you very much.

Hey @tinnapat,
Currently it's not really possible to set the service name (or any other resource attribute) in the opentelemetry-spring-boot-autoconfigure project. There's already an issue (#3480) about it.
