written in Hexagonal (Ports & Adapters) Architecture

This is a small application that provides basic REST endpoints for managing library (add new book, reserve, borrow it, etc.).

The technology behind it:

• Java 11
• Postgres
• Spring Boot

In the terminal run the following command:

$ docker-compose up

First compile an application:

$ mvn clean package

Then, you have two options either run it with H2 database or with local Postgres database. For first approach just run:

$ mvn spring-boot:run 

For a second option, check in the configuration file - src/main/resources/application.yml for profile local-postgres if connection details are correct and if so, run the command:

$ mvn spring-boot:run -P local-postgres

First configure how you run the LibraryHexagonalApplication.java by adding --spring.profiles.active=h2 (for H2 database) or --spring.profiles.active=postgres (for Postgres database) as a Program argument.

Then just run the LibraryHexagonalApplication.java class so it will use H2 database (you don't need to have postgres database up and running).
