Add support for SpEL expression in @Indexed [DATAMONGO-2112]

 Let say i have domain object like below. As developer i want to move expireAfterSeconds's value to application.properties file and replace 42 with smth like @Value("${life-universe-everything.answer}"), but it's not possible now. The only workaround is to use mongoTemplate. Please, add integration with Spring context into @Indexed annotation.

@Document
public class POJO {
    @Indexed(expireAfterSeconds=42, background = true)
    private Date creationDate = new Date();
    private String payload;
}

Hi there,

UPD: I guess it would be nice if annotation Indexed will have parameter expireAfterSecondsExpression that expects SPEL string e.g.

@Document
public class POJO {
    @Indexed(expireAfterSecondsExpression = "${life-universe-everything.answer}", background = true)
    private Date creationDate = new Date();
    private String payload;
}

Thanks

We have a case where we would like to reuse Spring Boot's DurationStyle. We want to await Spring Framework's response whether they want to include DurationStyle into the core before we proceed with our own implementation
