In AEM SPA com.adobe.aem.spa.project.core.models not found

[Ronnie09]

I have to override and modify getExportedPath() present inside spa page core model. I cannot find that in my import. I can find core component page but not the aem.spa.project.core but I can find the dependency are available even in system/console/bundle it is available and active 

For dispatcher I need to over ride and shorten the URL how can I do that if it is not available

Hi @Ronnie09,

This is expected, because implementation of models is part of internal package, which is not exported. You can find implementation under:

• https://github.com/adobe/aem-spa-project-core/tree/master/core/src/main/java/com/adobe/aem/spa/proje...

You should use delegate pattern in case you want to made some modification. This is standard approach for models from Core Components, and SPA models are not exception here.

• https://github.com/adobe/aem-core-wcm-components/wiki/Delegation-Pattern-for-Sling-Models

Sample code, that should give you an idea which direction to go.

package com.example.page;

import com.adobe.aem.spa.project.core.models.Page;
import com.adobe.cq.export.json.ContainerExporter;
import com.adobe.cq.export.json.ExporterConstants;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.models.annotations.Exporter;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.Via;
import org.apache.sling.models.annotations.injectorspecific.Self;
import org.apache.sling.models.annotations.via.ResourceSuperType;
import org.jetbrains.annotations.Nullable;

import java.util.Calendar;

@Model(
        adaptables = SlingHttpServletRequest.class,
        adapters = { Page.class, ContainerExporter.class },
        resourceType = CustomPageImpl.RESOURCE_TYPE
)
@Exporter(
        name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
        extensions = ExporterConstants.SLING_MODEL_EXTENSION
)
public class CustomPageImpl implements Page {

    static final String RESOURCE_TYPE = "custom/page/resource";

    @Self
    @Via(type = ResourceSuperType.class)
    private Page delegate;

    @Override
    public String getExportedPath() {
        // place for your implementation
    }

    // other methods from Page, use methods from delegate if you do not want change them y
    @Override
    public @Nullable Page getHierarchyRootModel() {
        return delegate.getHierarchyRootModel();
    }

    @Override
    public String getLanguage() {
        return delegate.getLanguage();
    }

    @Override
    public Calendar getLastModifiedDate() {
        return delegate.getLastModifiedDate();
    }

    @Override
    public String[] getKeywords() {
        return delegate.getKeywords();
    }

    // repeat for all other methods from Page
}

Hi @lukasz-m 

com.adobe.aem.spa.project.core.models.Page

this page is not coming up while overriding the Page

[lukasz-m]

Make sure you have included below dependency in your project pom. As it provides SPA project api.

<dependency>
   <groupId>com.adobe.aem</groupId>
   <artifactId>spa.project.core.core</artifactId>
   <version>1.3.12</version>
</dependency>

@lukasz-m 
Oh I forgot this thanks I can see it now.

I have overridden all the methods but all methods are returning null 

    private Page delegate;

this delegate via debugger I found that it is not null still methods are returning null.
