How to get session inside slingmodel

[#1]

Dear All,

I have one requirement like below. When Author will put the SKU Id in dialog , as shown in below,

After author will put the SKU Id (for example 12345) , then this ID will search in content/dam/site/skuid folder and the document where this sku id is attached will come as link .

I am trying to do this logic inside

@PostConstruct
private void initModel() throws Exception {

But , I am not getting any session "or" resource inside  initModel().

Can anybody tell me how can I achieve the above scenario ?

Hi @dipu2 

In order to get session,

• you can first get ResourceResolver object with 
  @SlingObject
  private ResourceResolver resourceResolver;
  
  
• Then in initModel() method, you can adapt it to session like
  Session session =resourceResolver.adaptTo(Session.class);
  
  

In order to get resource, you can use
@SlingObject
private Resource resource;

Hope it helps!

Thanks!

@dipu2,

It might be possible to get the session from the current session of the current request, but the session obtained may not have the correct permissions to the path: content/damsite/skuid. If the session have no permission to the content path, then you can get a content not found an exception. Also, Sling Models should be lightweight and should have minimal logic. Your requirement seems like there might be mid-weight logic that can be re-usable. This would be a great time to create an OSGIService & Service Users.

Implementation Idea:

• Create a new OSGIService called SkuIdService.
• The OSGIService will utilise a system user, http://www.aemcq5tutorials.com/tutorials/create-system-user-in-aem/
• The SkuIdService will be an interface.
• The SkuIdServiceImpl will be the implementation of SkuIdService, which will contain the logic.
• Your Sling Model will inject the OSGIService with @OSGIService with field injection or constructor injection.
• This OSGIService can be re-usable by other Sling Models or Services.

I hope this helps,

Brian.
