FHIR Authorization and Transaction Example - Spring Boot

Introduction

This is an example application of the camel-fhir component. We’ll be using camel-spring-boot as well for an easy setup.

The Camel route is located in the MyCamelRouter class.

This example will read patients stored in csv files from a directory and convert them to FHIR dtsu3 patients and upload them to a configured FHIR server. Each file is uploaded in a new transaction.

The example assumes you have a running FHIR server at your disposal, which is configured for basic authentication. You may use hapi-fhir-jpa-server-example. You can start it up by running mvn jetty:run.

By default, the example uses http://localhost:8080/hapi-fhir-jpaserver-example/baseDstu3 as the FHIR server URL, DSTU3 as the FHIR version, BASIC authentication (admin as username and Admin123 as password) and target/work/fhir/input as the directory to look for csv patients.

However, you can edit the application.properties file to change the defaults and provide your own configuration.

There is an example of a test in the MyCamelApplicationTest class, which mocks out the FHIR server, thus can be run without the FHIR server.

Build

You can build this example using:

$ mvn package

Run

You can run this example using:

$ mvn spring-boot:run

When the Camel application runs, you should see a folder created under target/work/fhir/input. Copy the file hl7v2.patient located in the src/main/data folder into it. You should see the following output:

2018-07-24 11:52:51.615  INFO 30666 --- [work/fhir/input] fhir-example: Converting hl7v2.patient
2018-07-24 11:52:52.700  INFO 30666 --- [work/fhir/input] fhir-example: Inserting Patient: {"resourceType":"Patient","id":"100005056","name":[{"family":"Freeman","given":["Vincent"]}]}
2018-07-24 11:52:56.995  INFO 30666 --- [ #2 - CamelFhir] fhir-example: Patient created successfully: ca.uhn.fhir.rest.api.MethodOutcome@270f03f1

The Camel application can be stopped pressing Ctrl+c in the shell.
