Sling Exporter with custom selector

[veds89382868]

Hi,

I'm trying to use sling exporter framework (Adobe Experience Manager Help | Developing Sling Model Exporters in AEM  , Apache Sling :: Sling Models to export sling model data. This is for Content As A Service.

My requirement is that, in CaaS REST api url, I should be able to pass query parameter so that we can return/export data accordingly based on the parameter value.

For that i added custom sling selector option in  Sling Model exporter to expose JSON accordingly.

Here is a snapshot of the class. If you look at it, i'm setting the "selector" attribute with "mobile"

The url i'm hitting:

http://localhost:6502/content/wcms/api/v1/as/devicedata.mobile.json

This give me error "

Invalid recursion selector value 'mobile'

It seems that the request is getting resolved by DefaultGetServlet instead of the dynamically generated Sling Models Exporter Servlets.

I can see the exporter servlets class here :http://localhost:6502/system/console/status-slingmodels

Any guidance is greatly appreciated.

Thanks

Ved

Hi,

Try below if helps:

@Model(adaptables = Resource.class, resourceType="/apps/myApps/components/myComponent", defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

@Exporter(name = "jackson", selector="mobile", extensions = "json", options = { @ExporterOption(name = "SerializationFeature.WRITE_DATES_AS_TIMESTAMPS", value = "true") })

Please check AEM Developer Learning : Sling Model Exporter in AEM 6.3 for more info

Hi Arun,

I already tried that. No success. I get the same error.

Invalid recursion selector value 'mobile'

Cannot serve request to /content/wcms/api/v1/as/devicedata.mobile.json in org.apache.sling.servlets.get.DefaultGetServlet

Not sure if i need to install any feature pack. I have these installed.

Hi,

I tried in AEM 6.3 works for me.

Except below dependancy, I didn't do anything.

I am accessing resource like http://localhost:4502/content/AEM63App/language-masters/en/jcr:content/mainContent/hero_banner.mobil...

where hero_banner is my component node which I specified at in model annotation resourceType="/apps/myApps/components/myComponent
