Fhir Subscription logic implemented in hapi or needs to be implemented?

[Thormgrim]

Hello there,

I'd like to use the Subscription Resource to notify my process of created questionnaire responses that have certain subjects and questionnaire refs.

I have read through the Javadoc and Github of Hapi Fhir but couldnt ascertain if the logic behind the subscription is already implemented ( especially the "checking created resources for critera" part ). 

So that is my question, is that logic already implemented inside hapifhir ?

The next question would be how would I define a criteria such as the questionnaireResponse having a specific patient ref, specific questionnaire and/or a specific identifier ?

Thanks for any help or insights in advance.

Hi,

Subscriptions are implemented, although not for every single delivery type. Have a look at SubscriptionRestHookInterceptor for an example. If you register this interceptor, your JPA server will begin processing REST HOOK subscriptions.

The unit tests for that class would be an ok starting point if you wanted to see how it works.

Cheers,

James

Okay thanks for the quick info. 

Will this work for the normal Hapi fhir Server aswell or is there a seperate interceptor for that one?

Thanks.

For the regular server, there is no equivalent. Subscriptions are pretty low-level stuff, I don't know that it would be possible to do it in a generic way and have it be useful. Unfortunately you'd have to implement from the ground up. The JPA code might be a useful guide though.

Hi All,

 

Iam working on Subscription with Resthook channel type of hapi-fhir V3.2.0, where iam getting error log as "Failure to handle Subscription payload" and
at the subscriber side Iam receiving that " No mapping found for HTTP request with URI [/hapi-fhir-jpaserver-example/Patient/102] in DispatcherServlet with name 'spring'".
Can anyone help me out with the issue.

Thank You.

This probably means your endpoint in the Subscription definition is wrong.

Thank you james,but i have given the correct end point url,

and my doubt is whether we  need to configure any other things explicitly to create a channel to receive endpoints.

Hi james,

My subscription resource is

{
  "resourceType": "Subscription",
  
  "status": "requested",
  "contact": [
    {
      "system": "phone",
      "value": "ext 4123"
    }
  ],
  "end": "2021-01-01T00:00:00Z",
  "reason": "Monitor new neonatal function",
  "criteria": "Observation?category=social-history",
  "channel": {
    "type": "rest-hook",
    "endpoint": "http://ipaddress:port/hapi-fhir-jpaserver-example",
    "payload": "application/fhir+json"
  }
}

[James Agnew]

Again, this looks like your endpoint is wrong.
