Hi @ashwinikhaple
If there is a sling model available and you want to fetch the same properties as a JSON response,so there is no need to create a Sling Servlet. You just need to export your sling model using jackson exporter and that’s all. Sling Model Exporter can be used as a web service or as a rest API.

Sling Model Exporter was introduced in Sling Models v1.3.0 which allows new annotations to be added to Sling Models that define how the Model an can be exported as a different Java object, or more commonly, serialized into a different format such as JSON.

@Model(adaptables = Resource.class, resourceType = { "wknd/components/content/image" }, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
@Exporter(name = "jackson", extensions = "json", options = { @ExporterOption(name = "SerializationFeature.WRITE_DATES_AS_TIMESTAMPS", value = "true") })
public class ModelComponent {

   @Inject
   String title;

   @Inject
   String description;

   @Inject
   String date;

   @Inject
   String URL;

   @Inject
   @Named("sling:resourceType")
   String slingResourceType;

   public String getDescription() {
      return description;
   }

   public String getDate() {
      return date;
   }

   public String getURL() {
      return URL;
   }

   public String getSlingResourceType() {
      return slingResourceType;
   }

   public String getTitle() {
      return title;
   }
}
