ACS AEM commons in JAVA

Avatar

Level 2

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,

Bhavani Bharanidharan

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.
