#adaptto

First you will have to create a Java project that later will be deployed into OSGI as a bundle. This bundle will have the Sling Model packages.

The POM of this project needs to have the maven-bundle-plugin declaration like in the following screenshot.

The <Sling-Model-Packages>section is very important. This will let OSGI know that the package path described there contains Sling Models classes/interfaces, and it will scan through it looking for the annotations. PLEASE don’t skip these plugin lines otherwise your models might not be mapped correctly.

SLING Model Interface or Class

Now you are ready to create models either using classes or interfaces. There are several annotations that will help you on this setup. The most common annotations are:

@Model Used to specify that the class represents a Sling Model.

@Inject Used to specify that a property represents a resource property.

Note: There are several others annotations and variations for Sling Models that might suite for different needs.

On my test case I've declared a UserInfo interface with two properties. The properties will be injected using the getter declarations.

import org.apache.sling.models.annotations.Model; import org.apache.sling.api.resource.Resource; import javax.inject.Inject; @Model(adaptables=Resource.class) public interface IUserInfo { @Inject String getFirstName(); @Inject String getLastName(); }

Testing Servlet

Now that we have our Sling Model ready, we just need to test it, for this I've created a simple servlet that pulls the resource and adapts it to our Sling Model.

The test Servlet will pull the resource by using the resource resolver:

Resource resource = resourceResolver.getResource("/content/myrpoject/en/test-sling/jcr:content/par/slingmodel");

Then you just need to adaptTo the resource to the specific Sling Model.

IUserInfo userInfo = resource.adaptTo(IUserInfo.class);

Then you can just print the different properties using the userInfo object.

Same thing you can do in an AEM component JSP, you just need to adapt the resource to the Sling Model.
