Query on ResourceChangeListener

Hi All,

I was trying to capture resource change events using ResourceChangeListener but, nothing is getting captured in log file.

Here, resource is - cq:page and it has one property called: 'interval' at /content/poll/jcr:content.

Here is my code -

import java.util.List;

import org.apache.felix.scr.annotations.Properties;

import org.apache.felix.scr.annotations.Property;

import org.apache.felix.scr.annotations.Service;

import org.apache.sling.api.resource.LoginException;

import org.apache.sling.api.resource.Resource;

import org.apache.sling.api.resource.ResourceResolver;

import org.apache.sling.api.resource.observation.ResourceChange;

import org.apache.sling.api.resource.observation.ResourceChangeListener;

import org.osgi.service.component.annotations.Component;

import org.osgi.service.component.annotations.Reference;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import com.aemtraining.service.SessionHandlerService;

@Component(immediate = true)

@Service(value = {ResourceChangeListener.class})

@Properties(value = {

@Property(name = ResourceChangeListener.PATHS, value = { "/content/poll/jcr:content" }),

@Property(name = ResourceChangeListener.CHANGES, value = { "CHANGED"}, propertyPrivate=true),

@Property(name = ResourceChangeListener.PROPERTY_NAMES_HINT, value={"interval"})

})

public class PropertyChangeListener implements ResourceChangeListener {

private final Logger logger = LoggerFactory.getLogger(getClass());

@Reference

private SessionHandlerService sessionHandlerService;

@Override

public void onChange(List<ResourceChange> resourceChangeList) {

ResourceResolver resourceResolver = null;

try {

resourceResolver = sessionHandlerService.getResourceResolver();

for (ResourceChange resourceChange : resourceChangeList) {

String resourcepath = resourceChange.getPath();

logger.info("******* RESOURCE PATH *******"+ resourcepath);

Resource resource = resourceResolver.getResource(resourcepath);

logger.info("******* RESOURCE NAME *******"+ resource.getName());

}

} catch (LoginException e) {

e.printStackTrace();

}

}

}

I am using AEM 6.3 and I have used archetype 11.

Please have a look and let me know if I have missed anything.

Thanks ,

Debal
