    ScriptStyleBaseRenderer and fingerprinting

    Elijah Baley Newbie

      Hi,

      We have scripts and css resources currently versioned with ?ver=XYZ123 by extending ScriptStyleBaseRenderer. (RF 4.2.2 Final) We would like instead to finger-print the resources. On the build side we'd like to use wro4j. it produces a mapping file similar to how RF does it: alias=fingerprinted-file.

       

      I was thinking at first that I would check wromapping.properties if the file has been remapped. And if so, write out the wro'ed url, otherwise do the default RF lookup:

      Resource resource = context.getApplication().getResourceHandler().createResource(name, library);

       

      But this would skip some steps of default RF resource handler, the dup checking, dependency checking, caching? What should the flow be? Is there a way to customize the resource loader/factory? Do I need to do that?

       

      Has anyone already attempted this?

          I checked into this further, it is possible to re-implement ResourceFactoryImpl with this:

          <application>   

                   <resource-handler>com.my.ExtendedResourceHandlerImpl</resource-handler>

          </application>

           

          and then in ExtendedResourceHandlerImpl constructor do:

          this.resourceFactory = new ExtendedResourceFactoryImpl(defaultHandler);

           

          This would allow me to change which mapping files are being loaded. It's a copy/paste of those two classes in their entirely because of how they are written in 4.2.2.Final. (I see that they were refactored in 4.3.3).  But instead, I think i will just copy over everything from /META-INF/richfaces/staticResourceMapping/Packed.properties into my user configured mapping file defined in web.xml

           

          @ConfigurationItem(names = "org.richfaces.resourceMapping.mappingFile")

          resourceMappingFile,

           

          web.xml 

          <context-param>

                  <param-name>org.richfaces.resourceMapping.location</param-name>

                  <param-value>http://localhost:8080/myapp/#{resourceLocation}</param-value>

          </context-param>

           

          Do you see any problems with that?

            Sounds reasonable, let us know how it works out, and if ther are any further extension points that need to be provided.
