Simple example application descrived in the post at: tomassetti.me
The article is available here: http://tomassetti.me/getting-started-with-spark-it-is-possible-to-create-lightweight-restful-application-also-in-java/
You need a PostgreSQL database. Run on it the code listed in the directory db. Done? Cool.
Now run the application. You can specify where to find your database, for example:
mvn exec:java -Dexec.args="--db-host myDBServer --db-port 5432"
See class BlogService for more details.
In the project there is also a Docker container for the DB, you can use it if you know what you are doing.
