Demo of the hexagonal architecture in the spring application.
The project simulates an online store. For the sake of simplicity, I mocked some data and provide only a few endpoints. Take a look at http://localhost:8080/swagger-ui.html to see all of them with a description.
The main idea was to demonstrate how to organize modules and packages, and cover them with tests, so the implementations don't really matter.
The presentation is available by this link
- Run a Postgres database from the container:
docker run --name hexagonal_postgres -d -p 5434:5432 -e POSTGRES_USER=sa -e POSTGRES_PASSWORD=password -e POSTGRES_DB=hexagonal postgres - Build it with maven to generate classes.
mvn compilewill do the job. (in Intellij you may need to reload maven project to find generated classes from thesoap.hexagonal.demo..package) - Run the main class
DemoApplicationas any other Spring Boot application.
To generate Liquibase diff file the next command from ./adapter/ folder: mvn liquibase:diff "-Dliquibase.url=jdbc:postgresql://localhost:5434/hexagonal" "-Dliquibase.driver=org.postgresql.Driver" "-Dliquibase.username=sa" "-Dliquibase.password=password" "-Dhibernate.dialect=org.hibernate.dialect.PostgreSQLDialect"
Pay attention that it won't work if you run it from the root folder!
