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

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

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

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 diferent 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.
