Hi @sateeshkreddy 

 

To get the logged-in user's name or ID in an AEM service impl .you can use the ResourceResolver and Request objects available in the service context.

 

Here's a code snippet demonstrating how to retrieve the logged-in user's information in an AEM service impl.

 

 

import org.apache.sling.api.resource.ResourceResolver; import org.apache.sling.api.resource.ResourceResolverFactory; import org.apache.sling.api.resource.LoginException; import javax.jcr.Session; @Component(immediate = true, service = YourService.class) public class YourServiceImpl implements YourService { @Reference private ResourceResolverFactory resourceResolverFactory; public void yourServiceMethod() { ResourceResolver resolver = null; try { // Get the ResourceResolver resolver = resourceResolverFactory.getServiceResourceResolver(null); // Access the current user's session Session session = resolver.adaptTo(Session.class); if (session != null && session.isLive()) { // Get the User object representing the logged-in user org.apache.jackrabbit.api.security.user.User user = (org.apache.jackrabbit.api.security.user.User) session.getUserPrincipal(); // Retrieve user ID and name String userId = user.getID(); String userName = user.getPrincipal().getName(); // Now you can use userId and userName as needed // ... } } catch (LoginException e) { // Handle login exception } finally { // Close the ResourceResolver when done to release resources if (resolver != null && resolver.isLive()) { resolver.close(); } } } }

You can get userId by adapt resourceResolver to Session.

Session session = resourceResolver.adaptTo(Session.class); session.getUserID();

 

To get User Name, Email, Groups, You need adapt resourceResolver to UserManager

Session session = resourceResolver.adaptTo(Session.class); UserManager userManager = resourceResolver.adaptTo(UserManager.class); /* to get the current user */ Authorizable auth = userManager.getAuthorizable(session.getUserID()); /* to get the property of the authorizable. Use relative path */ Value[] names = auth.getProperty("./profile/familyName"); Value[] emails = authorizable.getProperty("profile/email"); /* to get the groups it is member of */ Iterator<Group> groups = auth.memberOf();

    you can obtain the logged-in user's name or ID in a service implementation by using the ResourceResolver and UserManager classes. Here's a sample code on how to achieve this:

     

     

    import org.apache.sling.api.resource.ResourceResolver; import org.apache.sling.api.resource.LoginException; import org.apache.jackrabbit.api.security.user.UserManager; import javax.jcr.Session; import javax.jcr.RepositoryException; import org.apache.sling.api.resource.ResourceResolverFactory; @Component(service = ExampleService.class) public class ExampleService { @Reference private ResourceResolverFactory resourceResolverFactory; // ... public void exampleMethod() { try (ResourceResolver resourceResolver = resourceResolverFactory.getServiceResourceResolver(null)) { // Get the User ID and Name Session session = resourceResolver.adaptTo(Session.class); UserManager userManager = resourceResolver.adaptTo(UserManager.class); String userId = session.getUserID(); String userName = userManager.getAuthorizable(session.getUserID()).getPrincipal().getName(); // Use the userId and userName as needed // ... } catch (LoginException e) { // Handle the LoginException if there's an issue getting the ResourceResolver } catch (RepositoryException e) { // Handle the RepositoryException if there's an issue getting the UserManager } } // ... }

        Uhm, I want to use this way and my IDE blames the line "session.getUserPrincipal()". Reason: no method found. What does I miss?
