Hi @manasabojja7 ,
To achieve the desired behavior of maintaining the hierarchical order of tags when translated to keywords in the <meta> tag, you would typically need to customize the logic that generates the <meta> tag content. This customization can be done in the backend Java code of your AEM project.
Here's a high-level approach to implement this customization:
Retrieve Tags with Order: Modify the logic that retrieves the tags associated with the page to ensure that they are retrieved in the desired hierarchical order. You might need to query the tags with a specific order or sort them programmatically based on their hierarchy.
Generate Meta Keywords: Generate the <meta> tag content by concatenating the tags in the desired order, separating them with commas.
Inject Meta Keywords: Set the generated <meta> tag content as a property of your page's resource or as part of the response output. This can be done in your Java code where you handle the rendering of the page.
Here's a simplified example of how you might implement this logic in Java code (assuming you're using AEM's Sightly scripting language for rendering):
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ValueMap;
import com.adobe.cq.wcm.api.Page;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.ServletResolverConstants;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import java.io.IOException;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
@Component(
service = { Servlet.class },
property = {
ServletResolverConstants.SLING_SERVLET_PATHS + "=/bin/my/custom/servlet",
ServletResolverConstants.SLING_SERVLET_METHODS + "=GET"
}
)
public class MyCustomServlet extends SlingAllMethodsServlet {
@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// Retrieve the current page
Page currentPage = request.getResource().adaptTo(Page.class);
// Retrieve tags associated with the page
List<String> tags = Arrays.asList(currentPage.getProperties().get("cq:tags", new String[]{}));
// Sort the tags based on hierarchical order
List<String> sortedTags = sortTags(tags);
// Generate meta keywords content
String metaKeywords = sortedTags.stream().collect(Collectors.joining(", "));
// Set meta keywords as a property of the current page's resource
Resource pageResource = currentPage.getContentResource();
pageResource.adaptTo(ValueMap.class).put("metaKeywords", metaKeywords);
}
// Custom method to sort tags based on hierarchical order
private List<String> sortTags(List<String> tags) {
// Implement logic to sort tags based on hierarchy
// You might need to traverse the tag hierarchy and sort them accordingly
// For simplicity, I'll just sort them alphabetically
return tags.stream().sorted().collect(Collectors.toList());
}
}
In this example:
- MyCustomServlet is a servlet that retrieves the tags associated with the current page and generates the <meta> tag content.
- sortTags() is a custom method to sort tags based on the desired hierarchical order. You would need to implement the logic to sort tags according to your specific requirements.
- The generated meta keywords content is set as a property of the current page's resource (metaKeywords).
You would need to register this servlet in your AEM project and map it to an appropriate URL. Additionally, you might need to adapt this code to fit your specific project structure and requirements.
