Grails 3 + Springboot dependencies - grails

Question

I have a Grails 3 application that depends on dependencies that are managed by springboot. How to bootstrap those springboot dependend dependencies from Grails so i can use the services and beans from the dependensies.
Extending the Application.groovy packageNames funktion by the packages used in the dependencies seem to bootstrap most of it but not all....

Answer 1

this should do the trick:
class Application extends GrailsAutoConfiguration {
#Override
boolean limitScanningToApplication() {
false
}
}

Answer 2

The dependency that manages the MongoDB Connection is working fine if started standalone, but is not generating the MongoRepositories if used inside a grails application. It seems grails enables jpareporitories, but not MongoReporitories. I simply hat do add #EnableMongoRepositories to my MongoDB configuration and now both types of repositories are generated.
Summed up I had to use
class Application extends GrailsAutoConfiguration {
#Override
boolean limitScanningToApplication() {
false
}
}
to enable scanning as mentioned above and
#EnableMongoRepositories
to enable MongoRepositoryGeneration inside of a grails app
