Multiple Selector in custom Sling Model

Hi Team,

Is it possible to register a custom sling model with 2 or more selectors ? If yes, can please share how this can be achieved.

Can we use OSGI config to handle selector or resourceType to register a SlingModel ?

UseCase :

We have to export page content via custom Sling Model where in we can export complete page as JSON or specific component on that page as JSON as per selector used in the api endpoint.

Eg : <API ENDPOINT>.<SELECTOR1>.<COMPONENTID>.<EXTENSION>

Thank you in advance

Hi @dprakashraj

Thank you!

Yes you are right but our use is different. I am trying to achieve something similar to this question https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/best-way-to-expose-existing-pages-as-json/td-p/285282

All our component rendered using Sling Model.

This requirement is to expose existing/new pages as json via an endpoint similar to http://localhost:4502/content/we-retail/language-masters/en.customselector.abcd.json

where "abcd" is the componentID which is unique for every component . When requested via endpoint should only return JSON of respective component.

Main point is whether multiple selector possible in sling Model. If yes, can it be customisable instead of fixed in the sling model.

Thank you for responding to my query

I believe you want same sling model to return different json output based on the selector in the url. If that’s the case then on your sling model you can read the selector and based on that value to in can return the json of corresponding component.

final String selectorString = request.getRequestPathInfo().getSelectorString();

switch (selectorString) {
    case "fullreport":
        printFullReport();
        break;
    case "shortreport":
        printShortReport();
        break;
    case "printablereport":
        printPrintableReport();
        break;
}

Thank you @dprakashraj

This helps in handling multiple selectors.

Custom selector is not working with http://localhost:4502/content/we-retail/language-masters/en.customselector.abcd.json without adding jcr:content in the url ?

Thank you once again

Sling model can be registered with resourceType of your aem component.

I don’t think you need to register anything here. In your sling model you can read the sling selector from the url and send the response accordingly based on selector value. But in this case you need to adapt your sling model using sling servlet https://stackoverflow.com/questions/54457384/how-to-access-to-an-url-selector-at-a-component-level
