ACS AEM commons in JAVA

Hello,

I have requirement on archiving the assets, where i need to send a mail to the folder owners before one month of actual expiry date. So we are planning to take the folder owners mail id from the ACS AEM commons generic list.

I am looking for the help how we can access the generic list directly on backend without adding the ACS AEM commons on the component dialog as a datasource. If anyone knows the way to fetch the list value in the backend, kindly let me know here. Thanks much in advance.

 

 

Regards,

    Hi @bhavanibharani,

    import com.adobe.acs.commons.genericlists.GenericList; import com.adobe.acs.commons.genericlists.GenericListManager; import org.apache.sling.api.SlingHttpServletRequest; import org.apache.sling.api.resource.ResourceResolver; import org.apache.sling.api.resource.ValueMap; import org.osgi.framework.Constants; import org.osgi.service.component.annotations.Component; import org.osgi.service.component.annotations.Reference; import java.util.List; @Component( immediate = true, service = { MyService.class }, property = { Constants.SERVICE_DESCRIPTION + "=My Service", "sling.servlet.methods=GET", "sling.servlet.paths=/bin/my-service" } ) public class MyService { @Reference private GenericListManager genericListManager; public void myMethod(SlingHttpServletRequest request) { ResourceResolver resolver = request.getResourceResolver(); // Specify the path to your Generic List String listPath = "/etc/acs-commons/lists/my-generic-list"; GenericList genericList = genericListManager.getGenericList(resolver, listPath); if (genericList != null) { List<ValueMap> entries = genericList.getEntries(); // Now, you can iterate through the entries and retrieve the required information for (ValueMap entry : entries) { String value = entry.get("value", String.class); // Process the value as needed } } } }

    This example assumes that you have the ACS AEM Commons Generic List located at "/etc/acs-commons/lists/my-generic-list". Adjust the listPath accordingly based on your configuration. 

    Also, Generic Lists are not accessible to everyone by default on AEM as a Cloud Service Publish service. To make generic lists available on AEM Publish, set the appropriate jcr:read ACLs on either the /etc/acs-commons/list node, on specific list pages under /etc/acs-commons/lists. You can find the reference here

    Note: Make sure that the appropriate version of ACS AEM Commons is installed and the necessary dependencies are available in your project.

    Thanks

        Hi @bhavanibharani 
        Sling API to query the repository. Below is a sample Java code

        import org.apache.sling.api.resource.Resource; import org.apache.sling.api.resource.ResourceResolver; import org.apache.sling.api.resource.ResourceResolverFactory; import org.osgi.service.component.annotations.Reference; import com.adobe.granite.security.user.UserManager; import com.adobe.granite.security.user.User; import java.util.Iterator; import java.util.List; import java.util.Map; public class ACSCommonsUtil { @Reference private ResourceResolverFactory resolverFactory; // Method to get the email addresses of folder owners from ACS Commons Generic List public List<String> getFolderOwnersEmails(String folderPath) { List<String> emails = new ArrayList<>(); try (ResourceResolver resolver = resolverFactory.getServiceResourceResolver(null)) { // Path to ACS Commons Generic List String genericListPath = "/etc/acs-commons/lists/your-generic-list-name"; // Construct the path to the Generic List entry for the given folderPath String genericListEntryPath = genericListPath + "/" + folderPath.replace("/", "_"); // Get the Resource for the Generic List entry Resource genericListEntryResource = resolver.getResource(genericListEntryPath); if (genericListEntryResource != null) { // Assuming the property storing email addresses is named "emails" emails = genericListEntryResource.getValueMap().get("emails", new ArrayList<String>().getClass()); } } catch (Exception e) { // Handle exceptions } return emails; } // Method to get the folder owner's email from the user manager public String getFolderOwnerEmail(String folderPath) { try (ResourceResolver resolver = resolverFactory.getServiceResourceResolver(null)) { UserManager userManager = resolver.adaptTo(UserManager.class); // Assuming the folder owner's user ID is stored in the folder's "owner" property String ownerId = resolver.getResource(folderPath).getValueMap().get("owner", String.class); if (ownerId != null) { User user = (User) userManager.getAuthorizable(ownerId); return user.getProperty("profile/email", String.class); } } catch (Exception e) { // Handle exceptions } return null; } }

         This example assumes that you have ACS AEM Commons installed, and there is a Generic List containing email addresses for each folder. It also assumes that the user ID of the folder owner is stored in the "owner" property of the folder.
