@jeanbisutti this property is used by

opentelemetry-java-instrumentation/instrumentation/spring/spring-boot-autoconfigure/src/main/java/io/opentelemetry/instrumentation/spring/autoconfigure/internal/instrumentation/logging/LogbackAppenderInstaller.java

Line 19 in 5b21872

class LogbackAppenderInstaller {

- and I don't know if we can access @CofigurationProperties at that stage yet

[jeanbisutti]

Not sure what you mean.

From what I observe, @Value does not seem to work in LogbackAppenderApplicationListener.

org.springframework.boot.context.logging.LoggingApplicationListener does not use @Value .

@jeanbisutti please review

[jeanbisutti]

To help make the release note, could you please list the added properties in the description?

Are we sure that all the added properties are working? Perhaps it may be worth adding automatic tests.

@zeitlinger could you elaborate what this change is about. Did these list properties work at all previously or did the work in some different way? If the worked in some different way is this change backwards compatible?

New:

prop: a,b

OR

prop: [a,b]
