How to create (POST) multiple resources with one request?

[Gatoke]

Hello. Before I start I would like to admit I've checked that thread and the solution doesn't work to me: https://groups.google.com/forum/#!searchin/hapi-fhir/bundle%7Csort:date/hapi-fhir/7XLqp42yRfs/Tt6YAcFyBwAJ 

When I POST to the base URL of my jpa-server I receive an ERROR message:

10:10:20.043 [http-nio-8090-exec-6] WARN  c.u.f.r.s.i.ExceptionHandlingInterceptor - Failure during REST processing: ca.uhn.fhir.rest.server.exceptions.InvalidRequestException: This is the base URL of FHIR server. Unable to handle this request, as it does not contain a resource type or operation name.

When I use hapi-fhir-client the result is the same.

client.transaction()
        .withResources(of(bloodPressureObservation, meanBloodPressureObservation, heartRateObservation))
        .execute();

When I make a Bundle of my Observations and POST it - it is saved in jpa-server not as 3 Observations but as 1 Bundle. So when I GET /Observation I don't see them on the list.

My question is:
Is it possible to create multiple resources at once - instead of POSTing them one by one?

> UPDATE
1. I have an example of a Bundle. I send it to http://hapi.fhir.org/baseDstu2/?_format=json&_pretty=true which responses with success and 3 created Observations with IDs.

{"resourceType":"Bundle","type":"transaction","entry":[{"resource":{"resourceType":"Observation","meta":{"profile":["http://fhir.org/guides/argonaut/StructureDefinition/argo-vitalsigns"]},"status":"final","category":{"coding":[{"system":"http://hl7.org/fhir/observation-category","code":"vital-signs"}]},"code":{"coding":[{"system":"http://loinc.org","code":"55284-4"}]},"effectiveDateTime":"2019-09-15T12:22:48+02:00","component":[{"code":{"coding":[{"system":"http://loinc.org","code":"8462-4"}]},"valueQuantity":{"value":77.0,"unit":"mmHg","system":"http://unitsofmeasure.org","code":"mm[Hg]"}},{"code":{"coding":[{"system":"http://loinc.org","code":"8480-6"}]},"valueQuantity":{"value":127.0,"unit":"mmHg","system":"http://unitsofmeasure.org","code":"mm[Hg]"}}]},"request":{"method":"POST","url":"Observation"}},{"resource":{"resourceType":"Observation","meta":{"profile":["http://fhir.org/guides/argonaut/StructureDefinition/argo-vitalsigns"]},"status":"final","category":{"coding":[{"system":"http://hl7.org/fhir/observation-category","code":"vital-signs"}]},"code":{"coding":[{"system":"http://loinc.org","code":"8478-0"}]},"effectiveDateTime":"2019-09-15T12:22:48+02:00","valueQuantity":{"value":0.0,"unit":"mmHg","system":"http://unitsofmeasure.org","code":"mm[Hg]"}},"request":{"method":"POST","url":"Observation"}},{"resource":{"resourceType":"Observation","meta":{"profile":["http://fhir.org/guides/argonaut/StructureDefinition/argo-vitalsigns"]},"status":"final","category":{"coding":[{"system":"http://hl7.org/fhir/observation-category","code":"vital-signs"}]},"code":{"coding":[{"system":"http://loinc.org","code":"8867-4"}]},"effectiveDateTime":"2019-09-15T12:22:48+02:00","valueQuantity":{"value":89,"unit":"{beats}/min","system":"http://unitsofmeasure.org","code":"{beats}/min"}},"request":{"method":"POST","url":"Observation"}}]}

2. I do the same request to my local jpa-server: http://localhost:8090/fhir/?_format=json&_pretty=true I use the same body and headers and my server responses with:

{

    "resourceType": "OperationOutcome",

    "issue": [

        {

            "severity": "error",

            "code": "processing",

            "diagnostics": "This is the base URL of FHIR server. Unable to handle this request, as it does not contain a resource type or operation name."

        }

    ]

}

Any suggestions? :-)

Is this JPA server built with the starter project at: https://github.com/hapifhir/hapi-fhir-jpaserver-starter ?

If not, that is the first thing to try.

Cheers,

James

Thank you for your answer. I have a project based on https://github.com/jamesagnew/hapi-fhir/tree/master/hapi-fhir-spring-boot/hapi-fhir-spring-boot-samples/hapi-fhir-spring-boot-sample-server-jpa
And I looked at what you posted: https://github.com/hapifhir/hapi-fhir-jpaserver-starter and I discovered what is wrong.

Solution: I had to add JpaSystemProviderDstu2 to my RestfulServer configuration.

@Configuration
@RequiredArgsConstructor
class RestfulServerConfig implements FhirRestfulServerCustomizer {

    private final JpaSystemProviderDstu2 mySystemProviderDstu2;

    @Override
    public void customize(final RestfulServer restfulServer) {
        restfulServer.registerProvider(mySystemProviderDstu2);
    }
}

The bean of JpaSystemProviderDstu2 is automatically created on startup but it is not registered. I am curious why isn't it registered by default when using hapi-fhir-spring-boot-starter? 
Anyway - problem solved. :-) Thank you!

Glad to hear it!

If you're willing to submit a pull request to correct this, I'm sure others would appreciate it.

Same problem for me but I was not able to solve in this way, I've added the following lines (took from the jpaserver-starter) in the initialize() method of the class FhirAutoConfiguration:

     /*
      * Create a FhirContext object that uses the version of FHIR
      * specified in the properties file.
      */
     ApplicationContext appCtx = (ApplicationContext) getServletContext()
         .getAttribute("org.springframework.web.context.WebApplicationContext.ROOT");
     /*
      * ResourceProviders are fetched from the Spring context
      */
     FhirVersionEnum fhirVersion = properties.getVersion();
     ResourceProviderFactory resourceProviders;
     Object systemProvider;
     if (fhirVersion == FhirVersionEnum.DSTU2) {
       resourceProviders = appCtx.getBean("myResourceProvidersDstu2", ResourceProviderFactory.class);
       systemProvider = appCtx.getBean("mySystemProviderDstu2", JpaSystemProviderDstu2.class);
     } else if (fhirVersion == FhirVersionEnum.DSTU3) {
       resourceProviders = appCtx.getBean("myResourceProvidersDstu3", ResourceProviderFactory.class);
       systemProvider = appCtx.getBean("mySystemProviderDstu3", JpaSystemProviderDstu3.class);
     } else if (fhirVersion == FhirVersionEnum.R4) {
       resourceProviders = appCtx.getBean("myResourceProvidersR4", ResourceProviderFactory.class);
       systemProvider = appCtx.getBean("mySystemProviderR4", JpaSystemProviderR4.class);
     } else if (fhirVersion == FhirVersionEnum.R5) {
       resourceProviders = appCtx.getBean("myResourceProvidersR5", ResourceProviderFactory.class);
       systemProvider = appCtx.getBean("mySystemProviderR5", JpaSystemProviderR5.class);
     } else {
       throw new IllegalStateException();
     }
     setFhirContext(appCtx.getBean(FhirContext.class));
     registerProviders(resourceProviders.createProviders());
     registerProvider(systemProvider);

hope this helps.

Ciao

Ivano

Can you please give me full working example of above?
