ResourceFinders - order of looking into folders for resource

Hi,

We work with an extra ResourceFinder a lot, so that we can modify html
when webapplication is already running.
Now I want to change the html from a library, but the html is still in the
library. I can not remove it from there.. Is there some way I can override
this existing html, without removing it from the library? Something like
defining a ResourceFinder as the first to look from?
Thanks for any help ! Kind Regards, Marieke Vandamme

I.e.

package temp;

import org.apache.wicket.util.file.IResourceFinder;
import org.apache.wicket.util.resource.IResourceStream;

import java.util.List;

/**
 * CustomDelegatingResourceFinder
 */
public class CustomDelegatingResourceFinder implements IResourceFinder {

    private final IResourceFinder defaultFinder;

    private final List<IResourceFinder> others;

    public CustomDelegatingResourceFinder(IResourceFinder defaultFinder,
List<IResourceFinder> others) {
        this.defaultFinder = defaultFinder;
        this.others = others;
    }

    @Override
    public IResourceStream find(Class<?> clazz, String pathname) {
        IResourceStream resourceStream = defaultFinder.find(clazz,
pathname);
        if(resourceStream != null) {
            return resourceStream;
        }
        for(IResourceFinder finder : others) {
            IResourceStream stream = finder.find(clazz, pathname);
            if(stream != null) {
                return stream;
            }
        }
        return null;
    }
}

1- val customFinder = new CustomDelegatingResourceFinder(yourCurrentFinder,
app.getFinders())
2- app.setFinders(Collections.singletonList(customFinder)

Disclaimer: I haven't tried code above.

Hi,

Or simply create a finder that:

1- Do your default logic
2- Contains the finders on getResourceFinders()
3- You use setResourceFinders to set this unique resource finder (that
simply delegates n standard finder if your custom logic fails)

Hi Marieke,

I see that ResourceSettings exposes method getResourceFinders() which returns a List.
Assuming that’s where you register your custom finder, isn’t the easy solution to simply add it to the top of the list?

E.g. add(0, yourFinder) instead of add(yourFinder)?


Met vriendelijke groet,
Kind regards,

Bas
