Convert a Component into Experience Fragment with custom sling:resourceType

Avatar

Level 2

Hello Team,

 

When I convert a component into Experience fragment using 'convert to experience fragment variation', the experience fragment is getting created with 'sling:resourceType: cq/experience-fragments/editor/components/experiencefragment'.

But I want to replace the sling:resourceType with our custom Experience Fragment component path.

As checked, a servlet call has been posted to 'http://localhost:4502/libs/cq/experience-fragments/content/v2/conversion/converter'.

It calls a servlet 'ConvertToExperienceFragmentVariation' from 'com.adobe.cq.cq-experience-fragments' bundle.

But I could not extend the servlet as it is not part of the uber jar file. 

 

Can anyone guide me how to proceed with the requirement? Thanks in advance.

		if (request instanceof SlingHttpServletRequest && response instanceof SlingHttpServletResponse) {

			// Do work before sending the request down the Filter AND Sling processing chain
			final SlingHttpServletRequest slingRequest = (SlingHttpServletRequest) request;
			String componentPath = slingRequest.getParameter("componentPaths");
			log.info("Component path in filter is  ---->"+componentPath);
			Resource componentRes = slingRequest.getResourceResolver().resolve(componentPath);
			if(componentRes!=null)
			{
				ModifiableValueMap map = componentRes.adaptTo(ModifiableValueMap.class);
				log.info("current resource type --->"+map.get("sling:resourceType"));
				map.put("sling:resourceType", "<custom_component_path>");
				componentRes.getResourceResolver().commit();
				log.info("Successfully updated component path");
			}
			// The Request/Response have now been fully processed by Sling/AEM

		} else {
			// Else process the chain as usual.
			chain.doFilter(request, response);
			return;
		}

	}

}

 This can be achieved by implementing custom sling filter and updating sling:resourceType value. Above code does that, just update <custom_component_path> with your component path and this should work. I have tested this code on 6.5.10 version
