Hello.
Here’s the solution: Spring Boot integration with a differnet database - #2 by fiki574
EDIT:
My bad, you don’t have a standalone Spring Boot application, you would rather override the properties for the default database connection of the Flowable instance.
I use Docker, and here’s how I did it there:
SPRING_DATASOURCE_DRIVER-CLASS-NAME: org.postgresql.Driver
SPRING_DATASOURCE_URL: jdbc:postgresql://flowable-postgres:5432/flowable
SPRING_DATASOURCE_USERNAME: flowable
SPRING_DATASOURCE_PASSWORD: flowable
So the properties you’re overriding are correct, however it might be at a “wrong location” in the file system.
