Justin Edelson updated SLING-3715:
----------------------------------
Labels: models (was: )
> Sling Models: Support for class-based dependency injection
> ----------------------------------------------------------
>
> Key: SLING-3715
> URL: https://issues.apache.org/jira/browse/SLING-3715
> Project: Sling
> Issue Type: Improvement
> Components: Extensions
> Reporter: Stefan Seifert
> Priority: Minor
> Labels: models
>
> Currently Sling Models dependency injection is primary based on parameter
> name-based injection, and not on class-based injection (the latter is more
> common in Spring and comparable frameworks).
> here is Justins opinion on this topic (from the mailing list) and why he
> prefers name-based injection:

> Hi Stefan,
> The big problem IMHO with injecting by class vs. name is that by class
> is too ambigious in many cases. For example, in AEM, it is relatively
> common to want to inject a Page object, but in fact there are two
> different page objects which come into play (currentPage and
> resourcePage) and getting the wrong one could be highly problematic.
> You are correct that things like the request and response could
> presumably be injected by class rather than by name, but the question
> then becomes how do we judge these cases? In my opinion, the bindings
> names are sensible. I personally don't find myself wanting to write
> this very often:
> {code:java}
> @Inject
> private SlingHttpServletRequest somenameOtherThanRequest;
> {code}
> \[...\]
> Regards,
