从 ResourceResolverFactory 获取 ResourceResolver，但 ResourceResolver 无法通过给定路径获取 Resource

Question

Given siutation like this, author click publish (activate) a page Then I have following listener to handleEvent

public class ArticleContentActivationEventHandler implements EventHandler {


private static final Logger LOGGER = LoggerFactory.getLogger(ArticleContentActivationEventHandler.class);

private static final String ARTICLE_PAGE_TEMPLATE = "/conf/myproject/settings/wcm/templates/article-template";

@Reference
private ResourceResolverService resourceResolverService;

@Override
public void handleEvent(Event event) {

    ResourceResolver resourceResolver = null;
    try {
        resourceResolver = resourceResolverService.getServiceResourceResolver();
        String resourcePath = getResourcePath(event);
        Resource resource = resourceResolver.getResource(resourcePath);

        //the resource is null, the resource path is /content/myproject/us/en, 
        //resourceResolver is not able to resolve it somehow
        for (Iterator<Resource> it = resourceResolver.getResource("/content/myproject/us/en").getChildren().iterator(); it.hasNext(); ) {
            Resource r = it.next();
            String s = r.getPath();
            String t = r.getResourceType();
        }


        if (resource.isResourceType("cq:Page")) {
            Resource jcr_content = resource.getChild("jcr:content");
            ValueMap vm = jcr_content.getValueMap();
            String template = null;
            if (vm.containsKey("cq:template")) {
                template = PropertiesUtil.toString(vm.get("cq:template"), "");
            }

and below is the interface:

public interface ResourceResolverService {

ResourceResolver getServiceResourceResolver() throws LoginException;

void closeResourceResolver(ResourceResolver resourceResolver);
}

and the impl class:

@Component(service = ResourceResolverService.class, immediate = true)
public class ResourceResolverServiceImpl implements ResourceResolverService {

    @Reference
    private ResourceResolverFactory resourceResolverFactory;

    Logger logger = LoggerFactory.getLogger(ResourceResolverServiceImpl.class);

    @Activate
    protected void activate() {
        logger.info("*** Activating Service ResourceResolverServiceImpl");
    }

    @Override
    public ResourceResolver getServiceResourceResolver() throws LoginException {
        final Map<String, Object> param = Collections.singletonMap(ResourceResolverFactory.SUBSERVICE, (Object) "getResourceResolver");
        //the ResourceResolver returned here may got some issue?
        return resourceResolverFactory.getServiceResourceResolver(param);
    }

    @Override
    public void closeResourceResolver(ResourceResolver resourceResolver) {
        resourceResolver.close();
    }

}

I do have the osgi config setup by following tutorial http://www.aemcq5tutorials.com/tutorials/resourceresolver-from-resourceresolverfactory/

But in my actually even handler class, it never successfully resolved resource resourceResolver is not able to resolve /content/myproject/us/en, resourceResolver keep give me null value

Could anyone experienced this suggest me some code sample to resolve my issue? thanks

Check the User mapping configuration, the bundle id used in the configuration should match to your project core artifact id. For example: in the configuration bundleId = com.day.cq.wcm.cq-msm-core

Alternatively you can try below code instead

Map<String, Object> param = new HashMap<String, Object>(); param.put(ResourceResolverFactory.SUBSERVICE, "service-user"); ResourceResolver resolver = resourceResolverFactory.getServiceResourceResolver(param);
