Investigation of how to use Axon, Kotlin and Spring together

RabbitMQ quick quickstart

Install rabbitmq by using a package manager for your system:

$ sudo apt install rabbitmq-server

Configure rabbitmq - add web admin gui + user to connect:

# add web admin gui plugin
$ sudo rabbitmq-plugins enable rabbitmq-management

# configure the administrator so you can connect to web console
$ sudo rabbitmqctl add_user user user
$ sudo rabbitmqctl set_permissions -p user ".*" ".*" ".*"
$ sudo rabbitmqctl set_permissions -p / user ".*" ".*" ".*"
$ sudo rabbitmqctl set_user_tags user administrator

then you can connect to http://localhost:15672

Demo TODO

The usual Spring run works:

$ ./gradlew clean build -x test
$ java -jar build/libs/eventsourcing-0.0.1-SNAPSHOT.jar
...
spring console logging snip-snap
...
event received: TenantCreated(id=602224704, name=some tenant)
event received: TenantSuspended(id=602224704)
event received: TenantActivated(id=602224704)

DONE Make tests work. Currently they fail with org.axonframework.commandhandling.NoHandlerForCommandException. Tests use AggregateTestFixture.
Implement at least one tenant projection
DONE Implement API controller for tenants
Implement another aggregate root (UserProfile)
Implement KYC saga:
1. a new user starts sign-on process
2. user enters MSISDN
3. confirmation code is generated
4. SMS with confirmation code is sent
5. user presents confirmation code
6. a new user profile is created
Implement custom aggregate root repository for another aggregate (no event sourcing)
Connect everything
1. postgres
2. DONE ActiveMQ
