Configure taglib with spring about wro4j-runtime-taglib HOT 10 CLOSED

Maybe an instance of OptimizedResourcesRootProvider could be configured through spring?

from wro4j-runtime-taglib.

If wro4j is configured through spring, then the filter is often an instance of the dynamic proxy class org.springframework.web.filter.DelegatingFilterProxy. Additionally, there's no instance of WroServletContextListener.

from wro4j-runtime-taglib.

WroManagerFactory should be initialized before TaglibContext because TaglibContextFactory decorates WroManagerFactory. i.e. WroServletContextListener might still be required to create WroManagerFactory unless there would be a singleton bean for WroManagerFactory that would be injected/autowired.

Unfortunately, DelegatingFilterProxy doesn't provide a way to get a bean class name(s) and so we couldn't be sure that it actually delegates to WroFilter. findWebApplicationContext is protected i.e. it would require some spring-specific code and I believe that there might be a better solution:

I'm going to support something like this:

optimizedResourcesRootStrategy=predefined
optimizedResourcesRoot=/wro/

this class should probably also have a setter to allow setter injection.

Would it be an option to configure the TaglibContextFactory through spring as well?

from wro4j-runtime-taglib.

Actually, It might be already possible to initialize TaglibContext through spring because TaglibContext.initialize accepts ServletContext.
There is a prerequisite, though: WroManagerFactory should already be stored as an attribute. That's the reason why I suggested to use WroServletContextListener
Also, WroContextFilter is required to provide Context at runtime.

Do you have an example setting up a TaglibContext in spring? The crucial constructors in TaglibContext and TaglibContextFactory are package protected, making it a bit hard to initialize outside.

from wro4j-runtime-taglib.

Unfortunately, I don't have such an example. I may create one though.
Constructors in TaglibContext and TaglibContextFactory are package protected because TaglibContext should be initialized through TaglibContext.initialize so that it would be possible to retrieve TaglibContext using TaglibContext.get
I'm not entirely sure how do you want to configure taglib with spring. I believe that one way to do it is to create ServletContextAware bean and initialize TaglibContext there. As I mentioned before, WroManagerFactory should be initialized before TaglibContext and "persisted" in ServletContext as well.

Ok, got it set up now, but unfortunately, in DefaultOptimizedResourcesRootProvider.getFilterRegistrations(), servletContext.getServletRegistrations() is called, and this method cannot be called from outside of a servlet listener (throws an UnsupportedOperationException).

So I guess using a different resources root provider that just takes the config from properties as you suggested above is probably the best way forward. I had success with a dummy setup;

package com.github.lifus.wro4j_runtime_taglib.model.resource.uri.root;

import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;
import ro.isdc.wro.http.WroFilter;

public final class SpringOptimizedResourcesRootProvider extends AbstractOptimizedResourcesRootProvider {

public SpringOptimizedResourcesRootProvider(final ServletContext servletContext) { }

@OverRide
protected String findOutRoot() {
return "/resources/wro/";
}
}

Works well with 0.1.3-SNAPSHOT, thx!

from wro4j-runtime-taglib.

Closing this one for now as I'm going to include current implementation as is in 0.2.0 release. Feel free to reopen this issue or create a more specific one
