    Not sure what your use case is or what exactly you need to achieve at the end.

     

    - If you simply need to map some Sling model over some CF, then you need to look at this as like you would map a Sling model on any other Sling resource. Is the same approach. You write a Sling model, you add your Java properties mapping your CF properties, and you give it a path to read from /content/dam/path/to/your/cf/jcr:content/data/... And the example provided by @arunpatidar are more then enough.

     

    - If your use case is more about having a way to get CF data in JSON format to consume it in other place, not directly in a Sling model, maybe you can consider exploring other 2 options (JSON Exporter and GraphQL) explained in this thread https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/how-to-get-data-from-content-fragment-and-export-in-json-format/m-p/564867

      Hi @jitesh07 , Its pretty much a resource mapper, doesn't make any difference is a content fragment. Here's an example:

      • Create a Sling Model to represent the Content Fragment structure.
      • Inject the Content Fragment path using @ResourcePath.
      • Adapt the resource to Content Fragment and retrieve the data.
      • Access the data in HTL, displaying the Content Fragment values.

       

       

      // The content fragment path, injected from a property or passed dynamically @ResourcePath(name = "contentFragmentPath") private Resource contentFragmentResource; private Map<String, String> fragmentData = new HashMap<>(); @PostConstruct protected void init() { if (contentFragmentResource != null) { ContentFragment contentFragment = contentFragmentResource.adaptTo(ContentFragment.class); if (contentFragment != null) { for (String elementName : contentFragment.getElements()) { FragmentData fragmentDataElement = contentFragment.getElement(elementName).getValue(); fragmentData.put(elementName, fragmentDataElement.toString()); } } } }
