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;

    @inject
    @Via("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 {

    @inject
    private String contactName;

    @inject
    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.

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

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.
