How To Get Current Jackrabbit User In Felix Request Filter?

Question

I need to get current jackrabbit/session user when a request filter does filter. I've implemented filter class as my past question

Answer 1

From your previous question I assume you are using Apache Sling - if you follow my advice there and use a Sling-aware Filter, you can cast the request to SlingHttpServletRequest in the filter's doFilter(...) method.

The SlingHttpServletRequest's getResource() method then provides the current Resource, which you can adapt to a JCR Session which then provides the Jackrabbit user.

Something like (without any checks for the example)

((SlingHttpServletRequest)request).getResource().getResourceResolver().adaptTo(Session.class)...
