using h2 as standalone embedded code example

Example: H2 enabling remote database creation first

//Try this in your application.properties. It worked for me:

  spring.datasource.url=jdbc:h2:~/test
  spring.datasource.driverClassName=org.h2.Driver
  spring.datasource.username=sa
  spring.datasource.password=
  spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
