import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.context.annotation.Import

@SpringBootApplication
@Import(DynamoEventSourcingConfig::class)
class OrderApplication

fun main(args: Array<String>) {
    runApplication<OrderApplication>(*args)
}

application.yml

event-sourcing:
  dynamo:
    access-key-id: ${DYNAMO_ACCESS_KEY_ID}
    secret-access-key: ${DYNAMO_SECRET_ACCESS_KEY}

build.gradle.kts

dependencies {
    ...
    
    // Infrastructure:event sourcing
    implementation("com.example.ec:eventsourcing-core:1.0.0")
    implementation("com.example.ec:eventsourcing-dynamo:1.0.0")
}

class OrderApplication

fun main(args: Array<String>) {
    runApplication<OrderApplication>(*args)
}

application.yml

azure:
  cosmos:
    uri: ${YOUR_AZURE_COSMOS_URI}
    key: ${YOUR_AZURE_COSMOS_KEY}
    database: ${YOUR_AZURE_COSMOS_DATABASE}
event-sourcing:
  cosmos:
    database-name: ${YOUR_COSMOS_DATABASE_NAME}
