fhir-audit-prototype

This is a prototype project that illustrates how to generate AuditEvents that will be sent to a messaging service.

Implementation

Add a dependency to the following project in common-libraries:

<dependency>
  <groupId>gov.samhsa.c2s</groupId>
  <artifactId>fhir-audit</artifactId>
  <version>${c2s.common-libraries.version}</version>
</dependency>

Also add a dependency to spring-cloud-starter-stream-rabbit:

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>

To enable as a Sring Cloud Stream project, add a simple @EnableBinding annonation. This is used in TestServiceImpl. Next org.springframework.cloud.stream.messaging.Source is autowired into the class. Once the object to be sent to the queue is constructed, it is sent as shown below:

mySource.output().send(MessageBuilder.withPayload(auditEvent).build()); //auditEvent is the object to be sent to the queue.

The properties for RabbitMQ are specified in application.yml. It tells Spring Cloud Stream how to connect to the broker. We do not need to tell Spring Cloud explicitly to use RabbitMQ; it happens automatically by having that dependency in the classpath.

Prerequisites

  • Oracle Java JDK 8
  • Apache Maven
  • RabbitMQ. This service can be run in docker using docker run -d -p 15672:15672 -p 5672:5672 rabbitmq:latest.

Build

This project requires Apache Maven to build it. To build the project, navigate to the folder that contains pom.xml file using the terminal/command line.

  • To build a JAR:
    • Run mvn clean package
