What's the rule for ignoring types?

[lizongwu]

We're trying to instrument RestTemplate.getForObject method using otel.instrumentation.methods.include=org.springframework.web.client.RestTemplate[getForObject] , but it doesn't seem to work—no span has been created for it.

And we noticed that many classes from Spring Framework are being ignored by the configuration in AdditionalLibraryIgnoredTypesConfigurer.

Could you clarify the rules for ignoring types and how to determine which types should be ignored?

I don't think there are any rules for this. The excludes try to limit the number of classes that are considered for instrumentation. I personally wish that we could just delete these.
