SubmodelRepository using MongoDB instead of basyx.backend = InMemory

[kzoltner]

I tried running a SubmodelRepository using InMemory configuration.
I used this for application.properties:

server.port=8081

spring.application.name=Submodel Repository
basyx.smrepo.name = sm-repo
basyx.backend = InMemory

management.endpoints.web.base-path=/

and ran this command:

docker run --name=sm-repo -p 8081:8081 -v ./application.properties:/application/application.properties:ro eclipsebasyx/submodel-repository:2.0.0-SNAPSHOT

After startup, a GET request to localhost:8081/health takes very long and return DOWN.

I get this log output:

Seems like MongoDB is used and fails.

Thanks for pointing this out. We missed excluding some auto-configuration from the Submodel Repository. It is fixed now and the SNAPSHOT image is updated.
