Can't use properties in `@Indexed#expireAfter`

[Idane]

Hi,

I encountered an issue while trying to use a property in the expireAfter field of the @Indexed annotation.

Reproduction repository

I have a project with a duration property which I want to use for the TTL index, I tried the following:

@Document
class MyDocument(
    @field:Indexed(expireAfter = "#{\${app.duration}}")
    var ttlField: LocalDateTime = LocalDateTime.now()
)

and got the following stack trace:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sbmongoApplication': Unsatisfied dependency expressed through field 'repo': Error creating bean with name 'repo' defined in com.example.sbmongo.Repo defined in @EnableMongoRepositories declared on MongoRepositoriesRegistrar.EnableMongoRepositoriesConfiguration: Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations'

Also tried @Indexed(expireAfter = "#{@appProperties.duration}") and got a missing bean exception.

Support for property placeholders depends on spring-projects/spring-data-commons#2369 which will be part of the upcoming 2024.0 release.
