if you just want to try application you can use H2 file DB. Enable h2-file profile for that:
mvn clean package -Ph2-file
or just build
mvn clean package
Run using command line like (H2 file DB) from target directory
java -jar evotor-test-1.0-SNAPSHOT.jar ../src/main/resources/application.properties
Or configure application.properties choosing appropriate jdbc settings and don't forget to add jdbc driver to classpath and apply schema script like h2-schema. Implement SqlDialect and register in Application
