afterPropertiesSet

@PostConstruct
public void afterPropertiesSet()

processTransformation

public TransformedImageResponse processTransformation(String undecodedPathInfo)

Process the provided image transformation path information and return a transformed image.

This method requires the URL characters (including request parameters) that follow the servlet path in a URL. It needs the exact characters requested by the browser, i.e. none of them should be decoded.

So if the browser requested the following URL (where the context is "app" and the servlet path is "t")

"http://tr.com/app/t/scale/200x200/localhost:9090/img/%25D1%258B%2521%25E2%2584%2596%253B%2525%253D.png?a=1&b=2"

Then this method would expect

"/scale/200x200/localhost:9090/img/%25D1%258B%2521%25E2%2584%2596%253B%2525%253D.png?a=1"

Note: the Java request.getPathInfo() method is unsuitable as it only provides a decoded form of the URL and it doesn't include the servlet params. i.e. if you called request.getPathInfo() for the previous request you'd only get "/scale/200x200/localhost:9090/img/%D1%8B%21%E2%84%96%3B%25%3D.png".

Specified by:

processTransformation in interface UriTransformationManager<TransformedImageResponse>

Parameters:

undecodedPathInfo - the undecoded path plus the request parameters

Returns:

a processed transformation response
