How to call Sling Model Method with input parameter AEM

Question

I am having a scenario in which i want to call a sling model with input parameter. For this i have a code like this

Answer 1

From AEM 6.3 there is a new HTL feature that allows to do this.

In the data-sly-include and data-sly-resource you can now pass requestAttributes in order to use them in the receiving HTL-script. This allows you to properly pass-in parameters into scripts or components.

Java-code of the Settings class, the Map is used to pass in the requestAttributes:

public class Settings extends WCMUsePojo {

  // used to pass is requestAttributes to data-sly-resource
  public Map settings = new HashMap();

  @Override
  public void activate() throws Exception {
    settings.put("layout", "flex");
  }
}

For example, via a Sling-Model, you can consume the value of the specified requestAttributes. In this example, layout is injected via the Map from the Use-class:

@Model(adaptables=SlingHttpServletRequest.class)
public class ProductSettings {

  @Inject @Optional @Default(values="empty")
  public String layout;
}
