Export a component to JSON with multifield elements and display contact list in JSON

Question

Hello, I want to know how I can export a component to json when it has multifield elements

I have these classes but I don't really know how to display the contact list elements in the json

package com.program.core.models;

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Exporter;
import org.apache.sling.models.annotations.ExporterOption;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.Via;
import org.apache.sling.models.annotations.injectorspecific.SlingObject;

import javax.inject.Inject;
import java.util.List;


@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
@Exporter(name = "jackson", extensions = "json", options = {
    @ExporterOption(name = "MapperFeature.SORT_PROPERTIES_ALPHABETICALLY", value = "true"),
    @ExporterOption(name = "SerializationFeature.WRITE_DATES_AS_TIMESTAMPS", value = "false")
})
public class ContactCardsModel {
    
    @SlingObject
    SlingHttpServletRequest slingRequest;

    @586265
    @2434638("resource")
    public List<Contact> contact;

    public List<Contact> getContact() {
        return contact;
    }
}

package com.program.core.models;

import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;
import javax.inject.Inject;

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class Contact {

    @586265
    private String contactName;

    @586265
    private String contactEmail;

    public String getContactName() {
        return contactName;
    }

    public void setContactName(String contactName) {
        this.contactName = contactName;
    }

    public String getContactEmail() {
        return contactEmail;
    }

    public void setContactEmail(String contactEmail) {
        this.contactEmail = contactEmail;
    }
}

I would really appreciate if someone could give me an idea how to do it.

Hi,

You can find an example here of how to do it: https://gist.github.com/Surajkamdi/6d51779d62278b56a747e04532f39036

Pay attention to this code:

  //Multifield Child Resource for social links
  @ChildResource(name = "socialLinks")
  Collection<SocialLinksModel> socialLinks;

You can check how this work here: https://medium.com/@toimrank/aem-sling-model-exporter-90dc872835b9

Hope this helps.

Can you share what response are you expecting Vs what you are getting when calling AEM Content Services:
http://localhost:4502/content/practice/us/en/test.model.tidy.json

here test is a page, where you might have authored your component ContactCard
