opbeans/opbeans-java repository overview

⁠opbeans-java

This is an implementation of the Opbeans Demo app⁠ in Java as an Spring Boot⁠ application . It uses the same database schema as the Node⁠ version.

By default it will use a pre-populated in memory H2 database.

To run the application run the following command from the opbeans folder:

./mvnw  spring-boot:run

⁠Run locally

To run locally, including Server, Kibana and Elasticsearch, use the provided docker compose file by running the command

docker-compose up

⁠Run with Elastic Cloud

1. Start Elastic Cloud trial⁠ (if you don't have it yet)
2. Add environmental variables ELASTIC_CLOUD_ID and ELASTIC_CLOUD_CREDENTIALS (in format login:password)
3. Run

docker-compose -f docker-compose-elastic-cloud.yml up

⁠Testing locally

The simplest way to test this demo is by running:

make test

Tests are written using bats⁠ under the tests dir

⁠Publishing to dockerhub locally

Publish the docker image with

VERSION=1.2.3 make publish

NOTE: VERSION refers to the tag for the docker image which will be published in the registry

⁠Customize Database

Database can be overridden by using system properties and overriding values from the application property files:

./mvnw  spring-boot:run -Dspring.jpa.database=POSTGRESQL -Dspring.datasource.driverClassName=org.postgresql.Driver -Dspring.datasource.url=jdbc:postgresql://localhost/opbeans?user=postgres&password=verysecure

Another possible way is to create a different property file like application-customdb.properties and enabling it with a profile:

./mvnw  spring-boot:run -Dspring.profiles.active=customdb

⁠Demo notes

The application has a built-in bug that you can trigger by navigating to the path /is-it-coffee-time.
