Provide access to the return type in MethodMetadata [SPR-13024]

[spring-projects-issues]

Andy Wilkinson opened SPR-13024 and commented

We'd like to enhance Spring Boot's auto-configuration report to include the return type of any @Bean methods that have been conditionally included or excluded. We can't do so at the moment as MethodMetadata doesn't make that information available.

I'm happy to contribute a PR if you agree with the change and can offer some guidance on the implementation. The main decision that I can see is whether or not it's ok to change the MethodMetadata interface, or if the return type should only be exposed on the implementations (and we'd use a cast in Boot to access it).

No problem, as of 4.2, we've got a getReturnTypeName() next to the already added isStatic() on MethodMetadata...
