The IExHub XDS.b (iexhub-xdsb) Spring Boot project provides RESTful endpoints to allow applications to interoperate with standards-based Health Information Exchange (HIE) organizations. In particular, two endpoints are provided for sharing clinical records facilitating Cross-Enterprise Document Sharing (XDS.b) operations: (1) to get a patient's health data from the HIE, which in turn uses ITI-18 Registry Stored Query and ITI-43 Retrieve Document Set transactions and (2) to publish a patient's clinical record using ITI-41 Provide and Register Document transactions.

• Oracle Java JDK 8 with Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy
• Docker Engine (for building a Docker image from the project)

This is a Maven project and requires Apache Maven 3.3.3 or greater to build it. It is recommended to use the Maven Wrapper scripts provided with this project. Maven Wrapper requires an internet connection to download Maven and project dependencies for the very first build.

To build the project, navigate to the folder that contains pom.xml file using the terminal/command line.

• To build a JAR:
  • For Windows, run mvnw.cmd clean install
  • For *nix systems, run mvnw clean install
• To build a Docker Image (this will create an image with bhitsdev/iexhub-xdsb:latest tag):
  • For Windows, run mvnw.cmd clean package docker:build
  • For *nix systems, run mvnw clean package docker:build

This is a Spring Boot project and serves the API via an embedded Tomcat instance. Therefore, there is no need for a separate application server to run this service.

• Run as a JAR file: java -jar iexhub-xdsb-x.x.x-SNAPSHOT.jar <additional program arguments>
• Run as a Docker Container: docker run -d bhitsdev/iexhub-xdsb:latest <additional program arguments>

NOTE: In order for this project to fully function as a microservice in the Consent2Share application, it is required to setup the dependency microservices and the support level infrastructure. Please refer to the Consent2Share Deployment Guide in the corresponding Consent2Share release (see Consent2Share Releases Page) for instructions to setup the Consent2Share infrastructure.

This API utilizes Configuration Server which is based on Spring Cloud Config to manage externalized configuration, which is stored in a Configuration Data Git Repository. We provide a Default Configuration Data Git Repository.

This API can run with the default configuration, which is targeted for a local development environment. Default configuration data is from three places: bootstrap.yml, application.yml, and the data which Configuration Server reads from Configuration Data Git Repository. Both bootstrap.yml and application.yml files are located in the resources folder of this source code.

We recommend overriding the configuration as needed in the Configuration Data Git Repository, which is used by the Configuration Server.

Also, please refer to Spring Cloud Config Documentation to see how the config server works, Spring Boot Externalized Configuration documentation to see how Spring Boot applies the order to load the properties, and Spring Boot Common Properties documentation to see the common properties used by Spring Boot.

• java -jar iexhub-xdsb-x.x.x-SNAPSHOT.jar --server.port=80

• docker run -d bhitsdev/iexhub-xdsb:latest --server.port=80

• In a docker-compose.yml, this can be provided as:

version: '2'
services:
...
  iexhub-xdsb.c2s.com:
    image: "bhitsdev/iexhub-xdsb:latest"
    command: ["--server.port=80"]
...

NOTE: Please note that these additional arguments will be appended to the default ENTRYPOINT specified in the Dockerfile unless the ENTRYPOINT is overridden.

For simplicity in development and testing environments, SSL is NOT enabled by default configuration. SSL can be easily enabled by following the examples below:

• java -jar iexhub-xdsb-x.x.x-SNAPSHOT.jar --spring.profiles.active=ssl --server.ssl.key-store=/path/to/ssl_keystore.keystore --server.ssl.key-store-password=strongkeystorepassword

• docker run -d -v "/path/on/dockerhost/ssl_keystore.keystore:/path/to/ssl_keystore.keystore" bhitsdev/iexhub-xdsb:latest --spring.profiles.active=ssl --server.ssl.key-store=/path/to/ssl_keystore.keystore --server.ssl.key-store-password=strongkeystorepassword
• In a docker-compose.yml, this can be provided as:

version: '2'
services:
...
  iexhub-xdsb.c2s.com:
    image: "bhitsdev/iexhub-xdsb:latest"
    command: ["--spring.profiles.active=ssl","--server.ssl.key-store=/path/to/ssl_keystore.keystore", "--server.ssl.key-store-password=strongkeystorepassword"]
    volumes:
      - /path/on/dockerhost/ssl_keystore.keystore:/path/to/ssl_keystore.keystore
...

NOTE: As seen in the examples above, /path/to/ssl_keystore.keystore is made available to the container via a volume mounted from the Docker host running this container.

Java has a default CA Certificates Store that allows it to trust well-known certificate authorities. For development and testing purposes, one might want to trust additional self-signed certificates. In order to override the default Java CA Certificates Store in a Docker container, one can mount a custom cacerts file over the default one in the Docker image as follows docker run -d -v "/path/on/dockerhost/to/custom/cacerts:/etc/ssl/certs/java/cacerts" bhitsdev/iexhub-xdsb:latest

NOTE: The cacerts references given in the volume mapping above are files, not directories.
