SlingPostProcessor Example

[dherges]

Hi dudes,

i a veeeery fascinating project, stranger things have happened because some people didn't know about SlingPostProcessor ... https://sling.apache.org/apidocs/sling7/org/apache/sling/servlets/post/SlingPostProcessor.html

Maybe we should get a very veeerrrrrry nice example into ACS samples :-)

I'll try to open up a PR asap...

+2!

There is a PropertyMergePostProcessor in ACS Commons that could provide the framework for a POST processor.

In typical ACS Samples fashion, we should ad guidance in the the class comments on when to use them and when not to, and what the potential downsides are (they are called on all invocations of the Sling POST Servlet)

(they are called on all invocations of the Sling POST Servlet)

yeah, we used it by writing a simple accepts(SlingHttpServletRequest) that checks whether the PostProcessor should/must be triggered ... usually like if("my/resource-type".equals(request.getResource().getResourceType()) ...

Perfect for the sample!!
