Microprofile Showcase Application
General information
The application consists of several Microservices and a Web-Application managing a conference :
Microservice Name | Powered By | Description | Technologies |
---|---|---|---|
Schedule of the conference |
JAX-RS, CDI |
||
Sessions of the conference |
JAX-RS, CDI, JSON-P |
||
Speakers of the conference |
JAX-RS, CDI, JSON |
||
Votes for each session |
JAX-RS, CDI, JSON-P, MP Config, MP Fault Tolerance, MP Metrics, MP Health |
||
Frontend UI |
Angular2, Bootstrap4 |
The WebApp is a direct subscriber to the individual Microservices. This means that there is no aggregator / middle-man application. The WebApp itself provides a known relative EndPoint microservice that enables the lookup of URLs to the other services.
Quickstart - Run all services and UI in separate runtimes
This will run each service in the runtime container that its setup for and the UI in a Node.js server to interact with them.
Build, package and run all microservices and the UI:
mvn clean package -P start,ui
Run just the microservices:
mvn package -Pstart -pl :microservice-start
Run just the UI:
mvn package -Pui -pl :microservice-start
Running on Liberty
To run all the services on individual WebSphere Liberty servers add the 'liberty' profile to the command:
mvn clean package -P start,ui,liberty
mvn package -P start,liberty -pl :microservice-start
Development Build
mvn clean install -DskipTests
-
Build the projects using Maven (
mvn clean install
) or (mvn -fn clean install
) to skip over failed tests. -
To get the technical documentation, just
mvn clean generate-resources
under thedocs
directory. You will find a PDF and HTML version of the documentation underdocs/target/generated-docs
Development Tests
mvn clean test
Run Individual Services
Each service can run on any container (this is the Microprofile guarantee), but the service projects have been written by vendors to use their container. See the README.adoc of each microservice for details on how to run each microservice individually.

Common problems/bugs
NPM issues
The web-application project uses the com.github.eirslett:frontend-maven-plugin to download and install all node and npm requirements. Sometimes this may fail if console permissions are not permissive enough.
In such cases you will have to manually install some reqiurements:
-
Download and install node: https://nodejs.org/en/download/current/
-
Install npm manually:
cd web-application/src/main/static npm install npm npm install typings --global typings install --global
