Spring Boot 3.2.0 exposes Resource as a Bean, as a way to specify attributes to be included in tracing exports.

There is also a property map management.opentelemetry.resource-attributes, which allows the same via property configuration.

In the documentation, one can read:

Additionally, it provides a Resource bean. The attributes of the Resource can be configured via the management.opentelemetry.resource-attributes configuration property.

The documentation does not describe that exposing a Resource bean, will prevent the property from being able to provide attributes (unless the newly exposed Resource bean, implements it).

It would be more logical if the property was always used when provided by the user.

May I also suggest moving from Resource to Supplier<Resource>, with an ObjectProvider being used to consume multiple user-defined beans? That way the user is more flexible with how and where things are set up.
