> FileUploadInterceptor depends on implementation of MultiPartRequestWrapper
> --------------------------------------------------------------------------
>
> Key: WW-2544
> URL: https://issues.apache.org/struts/browse/WW-2544
> Project: Struts 2
> Issue Type: Improvement
> Components: Core Interceptors
> Affects Versions: 2.0.11.1
> Reporter: David Waite
> Fix For: Future
>
>
> The FileUploadInterceptor depends on the class/implementation of
> MultiPartRequestWrapper. This has become an issue with my efforts to wrap the
> HttpServletRequest as part of an authentication interceptor (made an
> interceptor to access annotations on the action class/method).
> The wrapper is not an interface, which makes it difficult to capture and
> delegate to the framework-created instance. In addition, the wrapper does not
> retain the properties of the HttpServletRequestWrapper, i.e. I cannot simply
> subclass and pass an existing MultiPartRequestWrapper-ish type in to add or
> override functionality. As far as I can tell, either I subclass it to make a
> true wrapper (delegating all methods to the input request) or I have to
> change the logic that creates the MultiPartRequestWrapper to instead create a
> subtype that gives me a setUserPrincipal method.
