App

This is a simple Spring Boot application example. Its most key features:

• two REST endpoints
  • GET actions
  • POST action
• DB usage
• dockerized deployment
• even some tests

Non-dockerized run

1. Set up DB & connection details in application.properties
   • in case of DB from docker compose - spring.datasource.url=jdbc:mysql://localhost:3307/db?autoReconnect=true
2. Run Application

Dockerized run

1. Assemble project
   1. In terminal perform ./gradlew assemble (you may need to specify org.gradle.java.home in gradle.properties; see this)
   2. or use Gradle tool window from IntelliJ (app/Tasks/build/assemble)
2. Run the following:

docker build -t app
docker-compose up -d

Note that the application container may fail a few times before a successful start. This is because it tries to connect the DB before the DB is able to accept a connection.

Usage

The app in both cases (non-dockerized and dockerized runs) can be accessed at http://localhost:8080. There are three REST endpoints: 0. GET /api/health

1. POST /api/action allowing the addition of action objects
2. GET /api/actions that gives all the actions from DB
